  • How vaccines work against COVID-19: Science, Simplified


    After we have been exposed to an infection, our immune system remembers the threat, in particular by producing antibodies. These are proteins that circulate in the blood and throughout the body; they quickly recognize and disable the invader upon contact, thereby preventing or minimizing illness. This is why we usually do not get sick with the same bug twice; we are immune. Vaccines mimic this process, encouraging the immune system to make antibodies without us having to go through the illness.

    Some of the leading SARS-CoV-2 vaccine candidates are “mRNA vaccines,” based on incorporating the genetic blueprint for the key spike protein on the virus surface into a formula that when injected into humans instructs our own cells to make the spike protein. In turn, the body then makes antibodies against the spike protein and they protect us against viral infection.
    This strategy is faster than more traditional approaches, which often involve generating weakened or inactivated forms of a live virus or making large amounts of the spike protein to determine whether they can prompt an antibody response.

    Once a potential vaccine is discovered, a number of checkpoints exist before it can be administered to people. First are preclinical tests, which involve experiments in a laboratory and with animals. Scientists must ensure the vaccine candidate is not only effective, but also safe. For example, an antibody response to an imperfect vaccine could, under extremely rare circumstances, end up increasing the danger of becoming infected.
    When the potential vaccine achieves the necessary preclinical results, clinical trials can begin in a small group of people. As the vaccine candidate advances, it is tested on increasing numbers of people, with scientists and doctors closely monitoring safety, efficacy and dosing. Upon successful completion of clinical trials, the vaccine candidate must be reviewed and approved by regulatory agencies such as the FDA before large-scale manufacturing and distribution gets underway and the licensed vaccine is administered widely.

    mRNA Vaccines for COVID-19. Vaccines are substances that protect you from harmful diseases. Most vaccines contain parts of weakened or dead germs that trigger your immune system to fight the disease. But mRNA vaccines for COVID-19 are different. They contain a substance, called mRNA, that teaches your cells how to make a protein that triggers an immune response. In order to understand how these vaccines work, it’s important to know what mRNA is and how it normally makes proteins your body needs. Most cells in your body have a “command center” inside them, called the nucleus. It contains genetic material, called DNA, that consists of instructions for building and maintaining your body. Proteins are one of the building blocks of your body. When a new body protein needs to be built, instructions for building it are copied from your cell’s DNA and converted into a “message,” called messenger RNA, or mRNA. Then, the mRNA travels out of the nucleus to a protein-building machine in your cell, called a ribosome. As the ribosome “reads” the “message” from the mRNA, it builds the protein your body needs. mRNA vaccines take advantage of this process to help give you immunity to COVID-19. Each vaccine contains special mRNA that provides instructions for your cells to build a harmless piece of the virus, called the spike protein. The spike protein is found on the surface of the SARS-CoV-2 coronavirus that causes COVID-19. Each piece of the mRNA from the vaccine is wrapped in a protective coating. The vaccine is given as a shot in the upper arm. In the body, the mRNA particles enter your cells. Once inside the cell, the mRNA travels to a ribosome. Using the mRNA from the vaccine, the ribosome makes only a piece of the spike protein from the virus. After making the piece of the spike protein, your cell destroys the mRNA from the vaccine. It’s important to know that the mRNA from the vaccine never enters the cell’s nucleus or changes its DNA in any way. Next, your cell presents the piece of the spike protein on its surface. This allows your immune cells to detect the protein and recognize that it doesn’t belong there. As a result, your immune cells begin making antibodies as part of an immune response to the virus. In the future, if you catch the virus, the antibodies recognize and attach to the spike protein pieces on infected cells and the spike proteins on the virus. This marks them for immediate destruction by other immune cells. Like all vaccines, the benefit of these mRNA vaccines is that they give vaccinated people protection from the virus without having to get sick with COVID-19. Most mRNA vaccines for COVID-19 require you to get a second shot within a few weeks. Sometime after getting the vaccine, you may have symptoms, such as a fever. This is normal. It means the vaccine is working to make you immune to the virus. Vaccines protect you, your family, and your community from diseases that can be dangerous, or even deadly.

  • POTENTIAL SIDE EFFECTS COVID VACCINE - COVID-19 Vaccine Adverse effects & Allergy


    COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19, without us having to get the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes, B-lymphocytes and antibodies that will remember how to fight that virus in the future.
    It typically takes a few weeks for the body to produce T-lymphocytes and B-lymphocytes after vaccination.
    Sometimes after vaccination, the process of building immunity can cause symptoms, such as fever, muscle pain, fatigue etc. These symptoms are normal and are a sign that the body is building immunity.
    So, it’s very important that you understand the minor side-effects of Covid vaccine and also we will discuss some of the rare but serious complications that can occur.

    Vaccines work by introducing a small number of bacteria, virus or toxin into the body. Because the bacteria, virus or toxin have been killed or weakened, there's no risk of contracting the disease in question. However, your body responds as if it were under attack, and mounts an immune response. If, in the future, you do encounter that disease, you'll have an army of cells and antibodies ready to fight it.

    Most common side effects include :
    Injection site pain • tiredness • headache • muscle pain • chills, swollen lymph nodes • joint pain • fever • injection site swelling • injection site redness & nausea

    Vaccines prepare the immune system, getting it ready to fight disease-causing organisms, called pathogens. A vaccine is introduced to the body to mimic infection, triggering the body to produce antibodies against the pathogen, but without causing the illness. Conventional vaccines usually contain a weakened or inactivated pathogen; or a piece of a protein produced by the pathogen, called an antigen.
    RNA vaccines are a new generation of vaccines. Instead of the antigen itself, RNA vaccines contain a messenger RNA – mRNA - that encodes for the antigen. Once inside the body’s cells, the mRNA is translated into protein, the antigen, by the same process the cells use to make their own proteins. The antigen is then displayed on the cell surface where it is recognized by the immune system. From here, the sequence of events is similar to that of a conventional vaccine.
    Some RNA vaccines also contain additional mRNA coding for an enzyme, which, after being translated in host cells, can generate multiple copies of the antigen-encoding mRNA. This essentially amplifies the production of antigen from a small amount of vaccine, making the vaccine more effective. These are called self-amplifying RNA vaccines.
    RNA vaccines are easier and safer to produce than conventional vaccines. This is because mRNA molecules can be synthesized in a cell-free system using a DNA template with a sequence of the pathogen; while conventional vaccines usually require a more complicated and risk-prone process of growing large amounts of infectious pathogens in chicken eggs or other mammalian cells. Without the risks of being contaminated by infectious elements or allergens from egg cultures, RNA vaccines are also safer for patients.
    Because protein synthesis occurs in the cytoplasm, RNA molecules do not need to enter the nucleus, so the possibility of them integrating into the host cell genome is low. RNA strands are usually degraded by cellular enzymes once the protein is made.
    The relative simplicity of the production process makes it easier to standardize and scale, enabling rapid responses to emerging pandemics. Other advantages include lower production costs, and the ease of tweaking RNA sequences to adapt to rapidly-mutating pathogens.
    On the minus side, it can be challenging to deliver mRNA effectively to the cells, since RNA sequences and secondary structures may be recognized and destroyed by the innate immune system as soon as they are administered intravenously. These limitations can be overcome by optimizing codons, using modified nucleosides to avoid recognition, and packaging RNA into protective nanoparticles.
    Another disadvantage is that most RNA vaccines require uninterrupted refrigeration for transportation and storage, which can be a hurdle for vaccine distribution. Research is ongoing to engineer thermostable vaccines.

  • COVID-19 vaccine side effects


    Vaccines are designed to give you immunity without the dangers of getting the disease. It’s common to experience some mild to moderate side effects when receiving vaccinations. This is because your immune system instructs your body to increase blood flow so more immune cells can circulate, and it raises your body temperature to kill the virus. Vaccines help protect us against disease and feeling mild or moderate side effects after receiving one is a sign that the vaccine and our immune system is working.

    Coronaviruses (CoV) are a family of viruses that cause sicknesses like the common cold, as well as more severe diseases, such as Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome. A novel coronavirus (nCoV) is a new strain – one that hasn’t previously been recognized in humans.
    Coronaviruses cause diseases in mammals and birds. A zoonotic virus is one that is transmitted between animals and people. When a virus circulating in animal populations infects people, this is termed a “spillover event”.
    How does CoVID-19 affect the body? The virus is fitted with protein spikes sticking out of the envelope that forms the surface and houses a core of genetic material. Any virus that enters your body looks for cells with compatible receptors – ones that allow it to invade the cell. Once they find the right cell, they enter and use the cell’s replication machinery to create copies of themselves. It is likely that COVID-19 uses the same receptor as SARS – found in both lungs and small intestines.
    It is thought that CoVID-19 shares many similarities with SARS, which has three phases of attack: viral replication, hyper-reactivity of the immune system, and finally pulmonary destruction. Early on in infection, the coronavirus invades two types of cells in the lungs – mucus and cilia cells. Mucus keeps your lungs from drying out and protects them from pathogens. Cilia beat the mucus towards the exterior of your body, clearing debris – including viruses! – out of your lungs. Cilia cells were the preferred hosts of SARS-CoV, and are likely the preferred hosts of the new coronavirus. When these cells die, they slough off into your airways, filling them with debris and fluid. Symptoms include a fever, cough, and breathing difficulties. Many of those infected get pneumonia in both their lungs.
    Enter the immune system. Immune cells recognize the virus and flood into the lungs. The lung tissue becomes inflamed. During normal immune function, the inflammatory process is highly regulated and is confined to infected areas. However, sometimes the immune system overreacts, and this results in damage to healthy tissue. More cells die and slough off into the lungs, further clogging them and worsening the pneumonia.
    As damage to the lungs increases, stage three begins, potentially resulting in respiratory failure. Patients that reach this stage of infection can incur permanent lung damage or even die. We see the same lesions in the lungs of those infected by the novel coronavirus as those with SARS. SARS creates holes in the lungs, so they look honeycomb-like. This is probably due to the aforementioned over-reactive immune response, which affects tissue both infected and healthy and creates scars that stiffen the lungs. As such, some patients may require ventilators to aid breathing.
    The inflammation also results in more permeable alveoli. This is the location of the thin interface of gas exchange, where your lungs replace carbon dioxide in your blood with fresh oxygen you just inhaled. Increased permeability causes fluid to leak into the lungs. This decreases the lungs’ ability to oxygenate blood, and in severe cases, floods them so that you become unable to breathe. Sometimes, this can be fatal.
    The immune system’s over-reaction can also cause another kind of damage. Proteins called cytokines are the immune system’s alarm system, recruiting immune cells to the infection site. Over-production of cytokines can result in a cytokine storm, where there is large-scale inflammation in the body. Blood vessels become more permeable and fluid seeps out. This makes it difficult for blood and oxygen to reach the rest of the body and can result in multi-organ failure. This has happened in the most severe cases of CoVid-19. Although there are no specific treatments for coronaviruses, symptoms can be treated through supportive care. Also, vaccines are currently in development.
    What can you do to protect yourself from CoVid-19? Basic protocol comes down to regular hand washing, avoiding close contact with anyone coughing or sneezing, avoiding unnecessary contact with animals, washing hands after contact with animals, thoroughly cooking meat and eggs prior to consumption, and covering your mouth and nose while coughing or sneezing. Respiratory viruses are typically transmitted via droplets in sneezes or coughs of those infected, so preventing their travel stops the spread of disease.

  • Covid Natural Immunity vs Vaccine Immunity


    There’s a lot of talk about “natural immunity” to Covid-19, and some people are refusing vaccination on the grounds that they’ve got this natural immunity thanks to a previous Covid-19 infection. In this episode we take a look at how infection and vaccination compare in terms of immunity, reinfection, and overall health risks and benefits.

  • Revolution in medicine - BioNTech, mRNA and the Covid-19 vaccine | DW Documentary


    With the help of mRNA technology, BioNTech has developed a vaccine for COVID-19. These assist the body to produce its own antigens to fight the virus - a medical milestone.

    Since the beginning of the 21st century, scientists Uğur Şahin und Özlem Türeci have pursued the goal of creating cancer treatments that are specific to individuals. The firm they established, BioNTech, focuses heavily on revolutionary mRNA technology.

    The M” in mRNA means messenger and RNA stands for ribonucleic acid. MRNA delivers information for antigen production directly to the cell which produces proteins. Afterwards, these cells present self-produced antigens on their outer shells and trigger a specifically desired immune response.

    Şahin and Türeci came up with the idea of using mRNA technology for vaccines in January 2020 after reading about a virus recently identified in Wuhan, China. Within hours, BioNTech decided to launch its search for a viable vaccine. The initial steps required lots of money and nerves of steel. The founders of pharmaceutical giant Hexal, brothers Andreas and Thomas Strünmann, were among the first financial backers.

    BioNTech received hundreds of millions in funding and the search for a vaccine began. But many questions remained unresolved. In the end, persistence paid off. A Partnership with Pharma Giant Pfizer sped up the testing phase and the Comirnaty Concentrate was approved. Its efficacy proven, millions around the world have been vaccinated with it.

    But what does the future look like for cancer research? And can mRNA technology aid in the fight against Malaria? The documentary shows what a wide-ranging affect this startup company in Mainz, Germany is having on global health. Film maker Michael Schindhelm has gained the opportunity to take a closer look at this revolutionary company.

  • Covid-19 vaccine side effects, explained


    Vaccinations for Covid-19 are now underway in the U.S. Two vaccines – one from Pfizer and BioNTech, one from Moderna — have received emergency use authorizations by the Food and Drug Administration. Both vaccines have been deemed safe, but they can cause some short-term side effects. Vaccines are designed to invoke an immune response that builds protection without causing a serious infection. Traditionally, vaccines are made with viral material which prompts the immune system to mount a defense. This process releases chemicals that cause physical symptoms — such as pyrogens, which are inflammatory chemicals that can cause fever.

  • Is Side Effect of Pfizer COVID-19 Vaccine Behind Rising Cases of Myocarditis in Israel?


    Israel has reported a small number of heart inflammation cases, mainly in young men who received Pfizer’s vaccine shots. Consequently, there is speculation in Israel of a probable link between Pfizer vaccine and myocarditis cases. However, Pfizer has ruled out any causal link between myocarditis and its vaccine.

    At least 275 cases of myocarditis have been reported in Israel between December 2020 and May 2021. Nearly 5 million people or 53.5% of the population have received the second jab in Israel so far.

    #Coronavirus #COVID-19 #Virus

    COVID-19 is the short name for the disease known as novel coronavirus disease 2019. Coronaviruses are a large group of similar viruses. Some are known to infect humans, such as SARS-CoV and MERS-CoV. The one that causes COVID-19 is called SARS-CoV-2. All coronaviruses are named for the crown-like “spikes” that cover their surface, called spike, or “S,” proteins. Inside the virus, genetic material, called RNA, is made up of genes. Genes carry the information to make more copies of the virus. The virus can infect you if it enters your mouth, nose, or lungs. Inside your body, the S protein of the virus locks to a receptor on the surface of one of your cells. This can trigger the virus to enter the cell in a couple of ways. It may cause the virus to fuse with the cell surface, then release its genes into the cell. Or, the cell may pull the virus inside by enclosing it in a sac. Once inside, the virus can fuse to the sac and release its genes. Next, the genes use a structure in your cell, called a ribosome, to make new copies of the virus. The new viruses travel to the surface of the cell. There, they can leave to infect more cells. In the meantime, viral S proteins left on the surface of the infected cell can cause it to fuse with nearby healthy cells, forming a giant cell. This may be another way for the virus to spread between cells. People may be infected with COVID-19 for two to fourteen days before symptoms appear. The three main symptoms of COVID-19 are: a fever, cough, and shortness of breath. Other symptoms may include: tiredness, body aches, stuffy nose, sore throat, diarrhea and vomiting, loss of appetite, and loss of smell. Most people have a mild illness and can recover at home. Some people who have the virus may not get sick at all or may show no symptoms. But, if you have trouble breathing, or any other symptoms that are severe, call your doctor or the emergency room. They will tell you what to do. For most people who have the virus, the risk for serious illness is thought to be low. People sixty-five years and older may have a higher risk for serious illness. And, people of any age may be at high-risk if they have underlying conditions, such as: chronic lung disease or asthma; serious heart conditions; diabetes; severe obesity; chronic kidney disease, and liver disease. High-risk groups also include people with a weakened immune system, including: those on certain medications, such as corticosteroids; people in cancer treatment; and those with HIV or AIDS. Even if you aren’t in a high-risk group, it’s important to practice social distancing, which means keeping at least two meters, or six feet, between you and other people. This helps prevent infections and serious illness in others as well as yourself. For up-to-date information about COVID-19 and other ways to prevent its spread, visit the CDC website.

  • What you need to know about COVID-19 booster shots


    Health officials are developing a plan to begin offering COVID-19 booster shots to all people in the U.S. as soon as this fall to maximize vaccine protection.

    But before booster shots can be offered, two things will need to happen:

    The Food and Drug Administration (FDA) will need to conduct an independent evaluation to determine the safety and effectiveness of a third dose of the Moderna or Pfizer messenger RNA vaccines.
    The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices will need to issue booster dose recommendations.
    As for those who received the Johnson & Johnson (J&J) COVID-19 vaccine, it's too soon to tell whether booster shots will be recommended.

    The Mayo Clinic News Network team sat down with Dr. Melanie Swift, co-chair of the Mayo Clinic COVID-19 Vaccine Allocation and Distribution Work Group. In this Q&A, Dr. Swift answers questions about COVID-19 booster shots:

    For the safety of its patients, staff and visitors, Mayo Clinic has strict masking policies in place. Anyone shown without a mask was recorded prior to COVID-19 or recorded in an area not designated for patient care, where social distancing and other safety protocols were followed.

    Information in this post was accurate at the time of its posting. Due to the fluid nature of the COVID-19 pandemic, scientific understanding, along with guidelines and recommendations, may have changed since the original publication date.

    The amount of time that the MRNA is actually in your body is probably 48 hours. And then after that, the only thing that remains is the memory of that vaccine. The kind of memory of what the spike protein looks like, so that if the body ever encounters the spike protein in an infection, it knows how to fight it. So, because of that, we feel very confident that there isn't any risk of long-term effects because the vaccine is not actually a part of your body for a very long time.
