    5:56

    How it works. mRNA vaccine (Pfizer, Moderna), DNA & Viral vector vaccines (Johnson & Johnson (J&J, JNJ), Oxford-AstraZeneca, Inovio, Sputnik V); protein/peptide vaccine (Novavax, EpiVacCorona), conventional inactivated (CoronaVac of Sinovac, Covaxin, Sinopharm). Mechanism of each type of coronavirus vaccines explained. Vaccine-induced immune response as compared to natural immunity.

    During a natural viral infection, infected cells alert the immune system by displaying pieces of viral proteins on their surface. They are said to present the viral antigen to immune cells - cytotoxic T-cells, and activate them.
    Debris of dead cells and viral particles are picked up by professional antigen-presenting cells, (dendritic cells...). Dendritic cells patrol body tissues, sampling their environment for intruders. After capturing the antigen, dendritic cells leave the tissue for the nearest lymph node, where they present the antigen to another group of immune cells - helper T-cells. Viral particles also activate B-cells.
    These cells mount 2 types of immunity specific to the viral antigen: cell-mediated immunity and antibody-mediated immunity.
    Vaccines deliver viral antigens to trigger immune responses without causing the disease. The events of a vaccine-induced immune response are similar to that induced by a natural infection, although some types of vaccines may induce only antibody-mediated immunity (B cell immunity, not T cell (cellular) immunity).
    Many existing vaccines contain a weakened or an inactivated virus. Because the whole virus is used, these vaccines require extensive safety testing. Live attenuated vaccines may still cause disease in people with compromised immune systems. Inactivated vaccines (Sinovac/China, Covaxin/India) only induce humoral (B cell) immunity.
    Subunit vaccines contain only part of the virus, usually a spike protein (peptide - EpiVacCorona/Russia). These vaccines may not be seen as a threat to the immune system, and therefore may not elicit the desired immune response. For this reason, certain substances, called adjuvants, are usually added to stimulate the antigen-presenting cells to pick up the vaccine.
    Nucleic acid vaccines contain genetic information for making the viral antigen, instead of the antigen itself. Naked DNA vaccines (Inovio, phase 2/3 clinical trials) require a special delivery method to reach the cell’s nucleus (electroporation). Alternatively, a harmless, unrelated virus may be used as a vehicle to deliver the DNA. In this case, the vaccine is also known as viral-vector vaccine (Sputnik V/Russia, Oxford-AstraZeneca, Johnson & Johnson's). For example, the Oxford-AstraZeneca Covid-19 vaccine uses a chimpanzee adenovirus as a vector. The adenoviral genome is modified to remove viral genes, and the coronavirus spike gene is added. This way, the viral vector cannot replicate or cause disease, but it acts as a vehicle to deliver the DNA. Why a non-human adenovirus is used?
    Do DNA vaccines change human DNA?
    mRNA vaccines (Pfizer, Moderna) are delivered within a lipid covering that will fuse with the cell membrane. The mRNA is translated into viral antigen, which is then displayed on the cell surface. mRNA vaccines are extremely unlikely to integrate into human genome.

  • COVID-19 Vaccines: MODERNA | PFIZER/BIONTECH | ASTRAZENECA

    43:41

    Official Ninja Nerd Website:
    Ninja Nerds!

    During this lecture Professor Zach Murphy will be discussing COVID-19 vaccines including Moderna, Pfizer/BioNTech, and Astrazeneca/Oxford.

    We are NOT sponsored and/or endorsed by Moderna, Pfizer/BioNTech, or Astrazeneca. We are presenting on RESEARCH and in no way is any of the information provided our own view or opinions.

    This will be a lecture packed with the process vaccine developers must go through; which includes a preclinical phase and phases I-III. Including information about OPERATION WARP SPEED and how this has expedited the normally lengthy vaccine process.

    We will then discuss how Moderna, Pfizer/BioNTech, and Astrazeneca vaccines work in the human body, preventing the SARS-CoV-2 virus and hopefully, ending this global pandemic.

    Finally-- Zach presents on all of the most current data that each of the vaccine companies have released outlining the vaccine procedure and how it will be administered, the vaccine efficacy (as a percentage), optimal storage temperature of the vaccine in order to remain viable, and the number of vaccine units these companies are capable of producing. We hope you enjoy this lecture and be sure to support us below!

    IMPORTANT INFO (MUST READ):
    One thing to emphasize that wasn’t harped on enough from this lecture is when these vaccines lead to an immunogenic reaction as we described above, which leads to formation of Memory B cells and Memory T cells. This is important because if we are exposed to the virus those memory cells are now primed and able to recognize and mount a powerful immune response against the virus.

    LASTLY, one additional point and clarification is when those cytotoxic T cells produce destructive molecules that damage host cells it’s important to realize that those are memory cytotoxic T cells primed by the Vaccine that damage host cells that ARE INFECTED with the SARS-COV-2 virus, NOT CELLS processing the vaccine.

    Big Takeaway:
    1. Vaccine stimulates antibody production to protect against virus IF INFECTED.
    2. Vaccine stimulates development of memory T and B cells to protect against virus IF INFECTED.

  • Covid-19 vaccines: Moderna vs. Pfizer vs. Johnson & Johnson comparison

    8:24

    We asked Dr. Stephen Thomas, chief of Infectious Diseases at SUNY Upstate Medical University, what we need to know about the vaccines right now and what we could learn in the coming months.

    Watch the video for a deeper explanation about the three vaccines currently available in the U.S. — Moderna, Pfizer/BioNTech and Johnson & Johnson. Moderna and Pfizer are messenger RNA, or mRNA vaccines and Johnson & Johnson is a viral vector vaccine. All three are designed to protect against Covid-19.

    According to the CDC, rather than inject the body with a weakened version of the coronavirus, these vaccines teach the body to make a protein which triggers an immune response. It’s those antibodies that our bodies produce that help keep us safe when confronted with the actual virus.

    Side Effects
    The mRNA vaccines have been administered to over 80 million people in the United States and they are safe and effective, Thomas said. Thomas was the lead principal investigator for the worldwide Pfizer/BioNTech vaccine trial.

    In data from the trials, Thomas noted, “The safety profile of these vaccines are all pretty similar, most people will experience some kind of pain at the site the vaccine was injected and most people say the pain is mild to moderate.

    Dr. Thomas also mentioned these other common side effects:
    • Mild to moderate headache
    • Mild to moderate fatigue
    • 30 to 40 percent of people might have muscle aches or joint pain
    • About ten to fifteen percent of people might develop a fever

    “The good news is if it’s going to happen to you, because it doesn’t happen to everyone, it happens pretty soon after you get vaccinated and once it starts it goes away within a couple of days,” Thomas said.

    “With Pfizer and Moderna rolling out over 80 million doses of vaccine the side effects continue to be the same as the data from the trials and we aren’t seeing any new side effects or more severe side effects,” he added.

    What about the variants?
    Work is being done in laboratories with the Moderna and Pfizer vaccines, testing people’s antibodies to see if the antibodies will neutralize the variants.

    Thomas said, “They are not as good at neutralizing those variants as they are against the predominant strain in the United States which is from China. But experiments are continuing and there is some concerning data there, which is why it’s important that we vaccinate as many people as possible, because it’s a race against the variants.”

    Thomas noted that the vaccines are still working at fifty to sixty-percent efficacy against the new variants.

    “Just to put it in context, the annual flu vaccine is about forty-five percent efficacious,” he said.

    How important is the two-dose vaccine time schedule?
    Thomas said it’s important to get these vaccines as close to the schedule as possible as they were tested in the trials. If a change is unavoidable, Thomas recommends delaying the second dose rather than getting it ahead of schedule.

    What is herd immunity and when will we have it?
    Herd immunity is achieved when enough of the population has become immune to a disease (generally through vaccinations) that it makes it difficult for that disease to spread.

    That would mean even those who are not immune would be protected.

    “Right now, about fifteen percent of the country has received at least one dose of vaccine, but that’s a far cry from the 70 to 80-percent that we are going to need to achieve herd immunity,” Thomas said.

    Thomas doesn’t think it’s going to be a vaccine supply issue, but more of a willingness for people to be vaccinated. “We’re vaccinating 2 million people a day, if that were to go to 3 million, and we have 320 million people in the country, we could achieve herd immunity by late summer.”

  • Infectious Disease Doctor Calls J&J COVID-19 Vaccine “A Game Changer”

    2:50

    #uvahealth #covidvaccine
    UVA Critical Care and Infectious Disease physician, Taison Bell, says he was excited about the availability of the one-dose COVID-19 vaccine from J&J. He explains how the vaccine works and addresses concerns that people may have about the vaccine’s efficacy numbers.

    Find out more about the vaccine at:

    Transcript

    TAISON BELL, MD: My name is Taison Bell. I'm a critical care and infectious disease physician at the University of Virginia.

    I was personally excited to see the Johnson & Johnson vaccine news, and then trial that came out and I expected it to be authorized by the FDA. It has a couple of advantages. So the first one is that it uses a slightly different platform. So instead of the messenger RNA that Moderna and Pfizer uses, this one uses a viral vector and adenovirus. And that's just a virus that causes the common cold, but it's modified so that it doesn't actually cause you to get sick. What it does do is allows a piece of DNA, so in opposed to RNA. It's a different vehicle, but the destination is the same.

    It’s teaching your body how to make the spike protein so that your body can make antibodies to it. And then later, if you get exposed to the coronavirus, you can rally the troops, get it out of there and prevent you from getting sick. So it works. The end game is the exact same.

    Now what I've gotten a lot of questions about is, well, what do I make of these different efficacy numbers? So, the 66% efficacy versus the 94-95%. Now you could sit back, and say, if I got the Johnson & Johnson, why would I want to take that? If I've got the Pfizer, Moderna, that I could just wait a little bit longer for? Now, this is what I want to talk about. You know, what does efficacy mean?

    If we dig down deeper into that data for Johnson & Johnson, and we think, you know, what are the things that we care about. People going to the hospital for COVID-19 with severe disease, people dying from COVID-19 from severe disease. They actually stack up pretty well against each other. So the Johnson & Johnson vaccine, for the 28 day period, before it takes for the vaccine to take full effect, from that point on, there were no people who went to the hospital with COVID-19. Absolutely zero. People who died from COVID-19, absolutely zero.

    So that 66% efficacy number is a little misleading because what this also is, is a life-saving vaccine. Now to put this in context, our flu vaccine is between 40 to 60% of efficacy. I take the flu shot every year, and it's something that we use as something to protect us from another deadly pandemic that happens on a global scale every single year. The Johnson & Johnson vaccine actually has higher efficacy than the influenza vaccine. And then when you combine that with the fact that if you look at people who've had the most severe illness and see that, you know, it really protects you against that with a one-dose regimen, that's easy to distribute, much easier to distribute. I think it's a game changer and personally for myself or my family members, if I had access to either one of them, that's the one that's going in my arm as quickly as possible, because I want the thing that's going to protect me from having a severe disease, from dying of COVID-19. And all three of these vaccines will do that.

  • Johnson & Johnson: Covid vaccine booster increases protection to 94%

    5:14

    CNBC's Meg Tirrell reports on Johnson & Johnson's coronavirus vaccine and the study results behind a second dose of its Covid vaccine. For access to live and exclusive video from CNBC subscribe to CNBC PRO:

    Johnson & Johnson said Tuesday its Covid-19 booster shot is 94% effective when administered two months after the first dose in the United States. It also said the booster increases antibody levels by four to six times compared with one shot alone.

    A J&J booster dose given six months out from the first shot appears to be potentially even more protective against Covid, the company said, generating antibodies twelvefold higher four weeks after the boost, regardless of age.

    When given as a booster, the vaccine remained well tolerated, with side effects generally consistent with those seen after the initial dose, according to J&J.

    “We now have generated evidence that a booster shot further increases protection against COVID-19 and is expected to extend the duration of protection significantly,” J&J chief scientific officer Dr. Paul Stoffels said in a statement.

    The new data, provided in a press release, helps J&J make a case to the Food and Drug Administration to authorize a booster shot to some 14.8 million Americans who have received the company’s single-dose vaccine.

    The Biden administration announced plans last month to roll out booster shots for people who received the Moderna and Pfizer vaccines. An FDA advisory committee on Friday unanimously recommended Pfizer booster shots to people age 65 and older and other vulnerable Americans. A final decision from the agency is expected any day now.

    U.S. health officials said they needed more data on the J&J vaccine before they can recommend boosters of those shots.

    The 94% efficacy rate for the J&J booster shot is for the U.S., the company said. Globally, a booster shot given about two months after the first dose is 75% effective against symptomatic infection, according to the company. It also demonstrated 100% effectiveness against severe and critical disease, it said.

    The company also released data from a real-world study that found a single dose of its vaccine provided strong and long-lasting protection against Covid-related hospitalizations, demonstrating 81% effectiveness after several months.

    The new data on a single dose will help the “critical” need “to prioritize protecting as many people as possible against hospitalization and death given the continued spread of COVID-19 and rapidly emerging variants,” the company said.

    “A single-shot COVID-19 vaccine that is easy to use, distribute and administer that provides strong and long-lasting protection is crucial to vaccinating the global population,” Stoffels said.

    In the US, the first two available Covid-19 vaccines were the ones from Pfizer/BioNTech and Moderna. Both vaccines have very high efficacy rates, of around 95%. But the third vaccine introduced in the US, from Johnson & Johnson, has a considerably lower efficacy rate: just 66%.

    Look at those numbers next to each other, and it's natural to conclude that one of them is considerably worse. Why settle for 66% when you can have 95%? But that isn't the right way to understand a vaccine's efficacy rate, or even to understand what a vaccine does. And public health experts say that if you really want to know which vaccine is the best one, efficacy isn't actually the most important number at all.

    Dr. Dana Mazo discusses the Johnson & Johnson COVID-19 vaccine.

  • AstraZeneca COVID-19 Vaccine EXPLAINED vs Pfizer vs Moderna vs Johnson & Johnson Coronavirus Vaccine

    4:49

    AstraZeneca COVID-19 Vaccine EXPLAINED vs Pfizer vs Moderna vs Johnson & Johnson Coronavirus Vaccine. Doctor Wagner, a real life emergency physician is back to discuss the latest on COVID-19, vaccine progress, Oxford/AstraZeneca covid 19 vaccine, how it works, the safety, effectiveness, side effects, reactions, trial, cases, and other covid news you need to know.

    Renewed concerns that the trajectory of COVID-19 cases in the U.S. is moving in the wrong direction. However, covid vaccine distribution is going strong. In the US, the first two available Covid-19 vaccines were mRNA vaccines from Pfizer/BioNTech and Moderna. Both vaccines have very high efficacy rates, of around 95%, even with the emergence of new COVID strains and the South African variants. But the third vaccine introduced in the US, from Johnson & Johnson, using virus-based technology, has a considerably lower efficacy rate: just 66%. Now a fourth coronavirus vaccine from Oxford/AstraZeneca has come forward. The AZD1222 vaccine against COVID-19 has an efficacy of 63.09% against symptomatic SARS-CoV-2 infection. However, some countries in the European Union have temporarily suspended use of the AstraZeneca COVID-19 vaccine as a precautionary measure based on reports of rare blood coagulation disorders (blood clots) in persons who had received the vaccine. Other countries in the EU – having considered the same information - have decided to continue using the vaccine in their immunization programmes. Now, Is AstraZeneca vaccine approved in US? Is there a safe vaccine for covid-19? Doctor ER Jordan Wagner will explain all of that in this covid 19 vaccine update news video. Have you received a COVID-19 vaccination yet? Let real doctor Jordan Wagner know in the comments!

  • Which Covid vaccine is the best? | Vaccine Effectiveness and Variants Explained

    14:00

    Which Covid vaccine is the best? Which Covid vaccine is the most effective? How do we measure vaccine effectiveness? Do Covid vaccines work against new variants? Is it possible that Covid vaccines may make things worse in the future?

    I answer all of these questions in this video. First, we compare the seven vaccines that have published phase 3 trial data as of June 2021. Those include Pfizer, Moderna, Sputnik, Johnson & Johnson, Sinopharm, and AstraZeneca. I look at the phase 3 trial data published in peer-reviewed journals.

    I compare the vaccine effectiveness between each vaccine. I also look at the differences in the phase III studies and see that the SARS-CoV-2 variants probably explain the differences in the vaccines. Each vaccine becomes less effective against variants that have more mutations, especially mutations on the spike protein, such as the E484K mutation, which can cause immune escape. Important mutations discussed include the South African variant, B.1.351, the Brazil variant, P.1, the UK variant, B.1.1.7, and the Indian variant, B.1.167.

    Finally, I explain why this matters. Countries, such as Thailand, Vietnam, and Malaysia, that have not yet had widespread Covid outbreaks may not be able to effectively use vaccines to prevent future outbreaks, as the current vaccines have substantially reduced effectiveness against the variants in those countries. I also explore the possibility that vaccines may initiate antibody-dependent enhancement, or ADE, which may make future infections worse for some people.

    0:00 Introduction
    0:53 How do we measure the effectiveness of a vaccine?
    2:13 Which Covid vaccines have published phase 3 trial data?
    3:36 How effective were Covid vaccines in phase 3 trials?
    5:48 How much do virus variants reduce vaccine efficacy?
    9:46 Not all effectiveness results can be compared
    10:30 The most vaccinated country had a Covid outbreak
    12:11 Possibility of future antibody-dependent enhancement

  • How SAFE is the AstraZeneca Covid Vaccine | Is There a Risk of Blood Clots? | Doctor Explains UPDATE

    6:33

    Update on the AstraZeneca covid vaccine and whether it is still safe to have. Recently, concerns have been raised about the risk of a very rare type of blood clot called CVST (cerebral venous thrombosis). We'll look at the numbers and facts around this vaccine.

    ???? SUBSCRIBE to my Newsletter ????Twice monthly | ???? Healthy living???????? Well-being ???????? Happiness ???? ​

    I have also included the latest data released by the MHRA (medicine regulator for the UK) which has shown that out of the 18 million vaccinated with this covid vaccine only 22 have developed CVST and of which 7 died. I stress at the moment no evidence has been found to link these with the vaccine but researchers are looking into this possibility.

    The EMA have also had a meeting on 29/03/21 about these rare types of blood clots but have not found a direct link or any risk factors for the patients who have had these. However further monitoring will be needed to investigate the rarer blood clots in the brain over time.

    I have had patients ask me: Is there a risk of blood clots (CVST)? Should I take the vaccine? How safe is the AstraZeneca and other covid vaccines? We'll explore these in this video.

    The general advice is that your risk is much higher with covid-19 and you should get vaccinated. Although much misinformation remains, and fear-mongering among the media and on social media. Please feel free to share this to help people who want to look at the facts and the science behind it all.

    For comparison of different vaccines, as well as events of immune response, role of different immune cells (T-cells, B-cells, APC), see this video:
    Johnson & Johnson COVID-19 Vaccine is a viral vector vaccine. It can also be classified as DNA vaccine or recombinant vaccines. It uses a modified adenovirus as a vehicle to deliver the coronavirus DNA. The adenoviral genome is modified to remove adenoviral genes, so it can no longer replicate or cause disease. The gene coding for coronavirus (SARS-CoV2) spike gene is then added. After being injected, the adenovirus vector delivers the coronavirus DNA to the nucleus of antigen-presenting cells (APCs). The DNA is transcribed into mRNA, which exits to the cytoplasm, where it is translated into coronavirus spike protein. This protein is then cut into pieces and presented on the surface of APC as antigens for the immune system to detect. APCs move to the nearest lymph node, where they present the antigen to T-helper cells, which play central role in immune response. Helper T-cells activate cytotoxic T-cells, leading to cell-mediated immunity, and induce B-cells to produce antibodies, resulting in antibody-mediated immunity. Both of these branches produce long-lived memory cells that will respond immediately upon viral infection.

  • WATCH: How the Johnson & Johnson COVID-19 vaccine works

    1:37

    Johnson & Johnson's COVID-19 vaccine was the third to be authorized in the United States, but it was the first to deliver full protection with one shot. Also different from the mRNA-based vaccines developed by Pfizer and Moderna, this one uses a viral vector -- in this case, an adenovirus -- to inoculate recipients against the coronavirus.

    On Thursday, Johnson & Johnson announced that new data from small studies suggest that its vaccine protects recipients against the more transmissible delta variant of the virus, and that overall protection lasts for at least eight months.

    Here’s a look at how it works.

  • What’s Different About the Johnson & Johnson COVID-19 Vaccine?

    5:59

    It’s official: The Johnson & Johnson vaccine has been granted emergency use authorization by the US FDA, joining the ranks of Moderna and Pfizer. Here's why this decision could be a game-changer for vaccine distribution.

    While not as high as Moderna’s and Pfizer’s 94 and 95% overall efficacy, this vaccine was found to be 85% effective against severe disease, regardless of the region or what variant it is exposed to. What’s more, it requires a single dose to work and doesn’t have specialized freezers — two attributes which could be a MASSIVE game changer for expanding access across the globe.

    Not only that, but the J&J vaccine is more durable than many of its counterparts, particularly those developed by Moderna and Pfizer.
    Also, unlike mRNA based vaccines, which are incredibly fragile and require cold storage to protect from damage, the J&J vaccine doesn’t require the same ultra-cold storage to stay intact. In fact, it can keep in a regular refrigerator for up to three months.

    So, how exactly did J&J bring this all together? Well, it all has to do with how its vaccine is formulated. Similar to the University of Oxford’s Astrazeneca vaccine and China’s CanSino vaccine, it uses a modified adenovirus as its vector: specifically, Ad26. That adenovirus is going to induce certain kinds of protective responses that will allow this little piece of COVID that we stuck into it to have a much greater effect. Once the little piece of COVID is inside the cell nucleus, its DNA code for creating a spike protein gets translated into RNA. The cell can then ‘read’ those instructions to make copies of the virus’s spike protein. These copies trigger the body’s immune response, helping it to become familiar with the virus and develop a plan of attack, should the two ever meet again.

    J&J’s single-dose COVID vaccine raises hopes for faster rollout

    US regulators have authorized Johnson & Johnson’s vaccine — which does not require a booster shot, and could simplify the logistics of mass vaccination.

    Why The Johnson & Johnson Vaccine Has Gotten A Bad Rap — And Why That's Not Fair

    First of all, I want to make the case that the J&J vaccine is not a lesser vaccine. And second is we absolutely should not be distributing these things based on socioeconomic status or any of those things.

    What are Adenovirus-Based Vaccines?

    Adenoviruses are considered excellent vectors for delivering target antigens to mammalian hosts because of their capability to induce both innate and adaptive immune responses.

  • Johnson & Johnson recommended - AstraZeneca questioned | DW News

    10:30

    One year after the WHO has declared COVID-19 a pandemic, the EU's drugs regulator has approved the use of the Johnson & Johnson single-shot Covid-19 vaccine.
    The US-American drug is the fourth to get the go-ahead from the European Medicines Agency. The EMA said the vaccine is 67% effective two weeks after innoculation. It's already being widely used in the United States and it's hoped this will help speed up the EU's slow vaccine rollout, which has drawn heavy criticism.
    This news comes as several announce that they have stopped using some batches of the AstraZeneca Covid 19 vaccine -- after reports of blood clots in some people. Denmark has suspended use of the vaccine until the matter is cleared up.

    The vaccine is being widely used in the United States and has the advantage of only requiring one dose, unlike the Pfizer, AstraZeneca and Moderna alternatives which all require two doses.
    The government announced it was ending negotiations with the company because it is the same type of vaccine as the AstraZeneca product which will be produced by the tens of millions in Australia.
    The federal opposition is demanding further explanation about why the government made this decision.

    Mixing Covid vaccines produces as much or more antibodies as using the same shot as a booster, according to preliminary results of a widely awaited U.S. government-sponsored trial. Today, FDA advisers begin meeting to debate whether people who got the Covid-19 vaccines made by Moderna Inc. and Johnson & Johnson should receive booster shots. Sam Fazelli of Bloomberg Intelligence discusses it all. (Source: Bloomberg)

    You will see in the video that these vaccines contain no human or animal proteins, but each company did use a cell line derived from HEK293 in order to amplify the amount of adenovirus needed for the vaccines.

    Additionally, there has currently been no evidence across the tens of thousands of people in clinical trials that the described ingredients in these amounts can cause harm. As always, happy to hear comments / questions!

  • How Oxford-AstraZenecas COVID-19 vaccine work - Adenovirus vector vaccine mechanism of action

    13:19

    In this video, Dr. Aizaz from MedicoVisual talks about mechanism of action of Adenovirus Vector Based DNA vaccine against Coronavirus (Sars-CoV-2) like Oxford-AstaraZeneca's (ChAdOx1 nCoV19 or AZD1222), Gamaleya's Sputnik 5, CanSino' Biologics's adenovirus type-5 (Ad5)-vectored COVID-19 vaccine, Johnson and Johnson's vaccine.
    These vaccines use Adenovirus vector to transport the double stranded DNA gene of Sars-CoV-2's spike protein into the cells thus train the immune system to fight against the actual virus.
    Adenoviruses are the etiological agents of common cold in human and are widely prevalent. Chimpanzee's Adenovirus or less common strains of human adenovirus are used in order to mitigate the problem of immunity against the vector itself. Furthermore, the adenovirus is modified in such a way so as to render it replication incompetent and non-infectious. E1 and E3 genes are deleted.

  • Expecting data on J&J vaccines effectiveness against the delta variant

    2:36

    CNBC's Meg Tirrell on the need for masks and booster shots to battle the new Covid delta variant. For access to live and exclusive video from CNBC subscribe to CNBC PRO:

    Moderna said Tuesday its Covid-19 vaccine showed promise in a lab setting against coronavirus variants, including the highly contagious delta variant first identified in India.

    The two-dose mRNA vaccine produced neutralizing antibodies against delta as well as beta and eta, variants first found in South Africa and Nigeria, respectively, according to Moderna.

    The company said the results were based on the blood serum of eight participants one week after they received the second dose of the vaccine. The data hasn’t yet been peer-reviewed. The results, while promising, may not reflect how the vaccines actually perform in real-world scenarios against the variants.

    Shares of Moderna jumped more than 6% in intraday trading after it announced the lab results.

    “We remain committed to studying emerging variants, generating data and sharing it as it becomes available,” Moderna CEO Stephane Bancel said in a press release. “These new data are encouraging and reinforce our belief that the Moderna COVID-19 Vaccine should remain protective against newly detected variants.”

    Moderna’s update comes days after World Health Organization officials urged fully vaccinated people to continue to wear masks, social distance and practice other pandemic safety measures as delta spreads rapidly across the globe.

    It also comes the same day Moderna said its vaccine was authorized for use in India, where the delta variant is thought to be behind the large outbreak there.

    Delta, now in at least 92 countries, including the United States, is expected to become the dominant variant of the disease worldwide. In the U.S., the prevalence of the strain is doubling about every two weeks.

    WHO officials said Friday they are asking fully vaccinated people to continue to “play it safe” because a large portion of the world remains unvaccinated and highly contagious variants, like delta, are spreading in many countries, spurring outbreaks.

    The comments were a departure from the Centers for Disease Control and Prevention, which has said fully vaccinated Americans can go maskless in most settings.

    “People cannot feel safe just because they had the two doses. They still need to protect themselves,” Dr. Mariangela Simao, WHO assistant director-general for access to medicines and health products, said during a news briefing.

    Authorized vaccines from Moderna, Pfizer-BioNTech and Johnson & Johnson have demonstrated to be highly effective in preventing Covid, especially against severe disease and death.

    Some variants, including delta, have shown to make the vaccines slightly less effective and WHO officials said they worry vaccinated individuals could become part of transmission chains.

    The Wall Street Journal reported Friday that about half of adults infected in an outbreak of the delta variant in Israel were fully vaccinated with the Pfizer vaccine, prompting the government there to reimpose an indoor mask requirement and other measures.

    In the U.S., President Joe Biden warned that unvaccinated people are especially at risk of becoming infected with delta.

    He said Covid deaths nationwide will continue to rise due to the spread of the “dangerous” variant, calling it a “serious concern.”

    “Six hundred thousand-plus Americans have died, and with this delta variant you know there’s going to be others as well. You know it’s going to happen. We’ve got to get young people vaccinated,” Biden said Thursday at a community center in Raleigh, North Carolina.
