What Is Shedding From Covid Vaccine

So Theres No Chance Then

Is Covid âVaccine Sheddingâ? Real? Does the COVID Vaccine Affect Fertility or the Placenta?

Zero, zip, nada. Theres no chance of viral shedding as a result of your COVID vaccine. If you do need to go to the shops in an outbreak area, follow the health advice to wear a mask and socially distance.

If youre vaccinated, youre likely to pose less risk to others than if youre unvaccinated. So businesses should be wooing you rather than turning you away.

What Happens To The Spike Protein

In both of these vaccine technologies, the spike protein thats produced is transported to the surface of the cell. This allows it to be detected by the immune system.

Once your immune system recognizes the spike protein as foreign, it will work to generate an immune response against it. This immune response is targeted specifically at the spike protein.

As such, vaccine-generated spike proteins are eventually destroyed by your immune system. They cant accumulate or circulate significantly in your body, nor can you shed them into the environment.

Some research has shown that very sensitive tests can detect minute levels of a piece of the spike protein in the blood in the days after vaccination. But these pieces of spike protein rapidly decline as the immune response kicks in.

Experts Have Moved Quickly To Rebuff Claims Covid

As the US struggles to turn a tide of vaccine hesitancy in favor of getting covid-19 doses into as many arms as possible to bring an end to the pandemic within its own borders and to do its bit toward reopening international travel and the global economy, epidemiologists and health experts are facing a new threat to vaccine confidence: so-called vaccine shedding.

Vaccine shedding is a term used to describe the release of a virus from a live-virus vaccine: essentially the possibility of a person who has received a vaccine passing on potential secondary effects to other people. However, as the CDC points out, none of the vaccines currently in use or in development in the United States contain the live virus that causes covid-19, making vaccine shedding an impossibility.

Shedding After Vaccine No Asyptomatic And Contagious

Dr. Keith Roach

DEAR DR. ROACH: In a recent column, you wrote that there is no risk to family from shedding after receiving the COVID-19 vaccine. You failed to mention that according to the Centers for Disease Control and Prevention, the grandparents could catch COVID and spread it even after being fully vaccinated.

Also, according to the CDC, they might be contagious and have a viral load, even before they start showing any symptoms. Isnt the only way to ensure they are not contagious to be tested? D.I.

ANSWER: The topic of that column was shedding after a vaccine, and it is true there is no risk of shedding COVID-19 from the vaccination. However, you are correct that it is possible for a vaccinated person to have active, asymptomatic infection.

New data from the age of the delta variant shows that asymptomatic, vaccinated people may indeed by infectious. For this reason, wearing a mask remains important, especially around people at high risk for complications for COVID-19. That includes vaccinated individuals.

Its very important to note that the risk of asymptomatic infection spreading from a vaccinated person is much lower than from an unvaccinated person, simply because someone who is vaccinated is a lot less likely to get COVID-19.

Live Virus Vs Protein

Moderna boss says COVID shot not proven to stop virus ...

The distinction between a vaccine using a live virus and a vaccine that uses a harmless part of a virus, such as a protein, to trigger an immune response is important, Offit said.

Vaccines using a part of a virus to start a response, such as the spike protein produced by both the Pfizer/BioNTech and Moderna mRNA vaccines, cannot lead to the virus reproducing and shedding. The Johnson & Johnson vaccine is a viral vector vaccine. It uses a harmless adenovirus, modified so that it cant replicate, to deliver instructions to cells to produce the spike protein, so the vaccine cant lead to shedding either. But vaccines using a live virus can replicate and shed.

Offit said an example of a vaccine that sheds or creates whats called contact immunity is the oral polio vaccine, which is no longer in use in the U.S. In that case, Offit said, people are given virus strains through the mouth the virus then reproduces in the intestine and is shedded in the feces. Unvaccinated people pick up the virus from the vaccine mostly by touching things a vaccinated person had touched, especially if that person didnt adequately wash their hands.

Micaela Martinez, an infectious disease ecologist at Columbia University who has studied the history of polio, said indirect vaccination is usually a good thing. It has been a really great thing for eradication initiatives, she said, and its usually not harmful because it uses an attenuated virus, with very little or no capability to cause disease.

Vaccine Shedding Conspiracies Dangerous

You might have seen claims about ‘vaccine shedding’ making unvaccinated people sick – we’ve debunked this claim

TheJournal.ie May 1, 2021

This is a conspiracy that has been created to weaken trust in a series of vaccines that have been demonstrated in clinical trials to be safe and effective, Dr Christopher Zahn, Vice President for Practice Activities at the American College of Obstetricians and Gynecologists, the leading US organization for medical professionals in womens healthcare, said in a statement. In response to a fact-checking request from Reuters, Dr Zahn added that such conspiracies and false narratives are dangerous and have nothing to do with science.

The CDC also released a similar statement in response to a Reuters request: “Covid-19 vaccines do not use the live virus that causes covid-19 and cannot cause covid-19. Therefore, people who receive a covid-19 vaccine cannot shed the virus or the vaccine.

Live Vs Inactivated Vaccines

Live vaccines contain a weakened form of a virus or bacteria that, when introduced into the body, will stimulate an immune response in the form of antibodies. This is in contrast to inactivated vaccines in which the virus or bacteria is dead yet is still recognized by the immune system as harmful, triggering the same antibody response.

Live vaccines are thought to better simulate natural infections and usually providelifelong protection with one or two doses. Most inactivated vaccines, by contrast, require multiple primary doses and booster shots years later to get the same level of immune protection.

Live attenuated vaccines have a long history of safety and efficacy but also have their limitations. People who are immunocompromised, for example, typically avoid live vaccines because their lack of immunity can make them ill if one is given.

Live attenuated vaccines currently licensed in the United States include:

  • Adenovirus vaccine
  • Chickenpox vaccine
  • Yellow fever vaccine

Two live attenuated vaccines commonly used in the pastthe smallpox vaccine and the oral polio vaccine are no longer used in the United States.

Of vaccines listed above, only two are used to prevent a bacterial infection. All others are used to prevent viral infections. The Bacille Calmette-Guérin vaccine is also sometimes used as a treatment for bladder cancer.

/5is ‘vaccine Shedding’ Possible In Covid

Will COVID-19 Vaccines Shed Their Components Into My Body?

Myths and misconceptions around coronavirus vaccines have been circulating in and around the world, leading to vaccine hesitancy and an increase in the number of COVID-19 cases. As is known and understood, vaccines are a mimicry of the original virus, which when injected into a person, activates the body’s immune system to recognize the pathogen and respond to it. This in turn causes some side-effects and in some cases even triggers adverse reactions.

After receiving a certain type of vaccine, you may have heard of something called ‘vaccine shedding’, where vaccinated individuals shed vaccine components.

While possible, it does not occur in anyone who has received any of the COVID vaccines manufactured so far. Not all vaccines are produced in a similar fashion and there are many things that need to be understood before believing any sort of information. That said, here is everything you need to know about vaccine shedding and whether or not COVID vaccines pose any risk at all.

Vaccinated People Are Likely Safer

Rather than banning vaccinated people from businesses for fear of viral shedding, owners should be welcoming them with open arms.

Thats because evidence is mounting vaccinated people are less likely to transmit SARS-CoV-2 to others.

In England, people who became infected despite being vaccinated with either the Pfizer or AstraZeneca vaccines , were only half as likely to pass their infection on to household contacts compared to infected people who were not vaccinated.

In Israel, people who had a breakthrough infection after the Pfizer vaccine had less virus cultured from their nose than people who had not been vaccinated.

Covid Vaccines Don’t Contain Live Virus To Shed

However, none of the COVID vaccines approved for use anywhere around the world so far use live viruses. Instead, they use other technologies to train our bodies to recognize SARS-CoV-2 and to mount a protective immune response should we ever be exposed to it. For instance, the AstraZeneca vaccine is a viral vector vaccine. This uses a modified chimpanzee virus to carry into the body the genetic instructions to produce the SARS-CoV-2 spike protein. Your body then uses these instructions to make the spike protein and to raise a protective immune response.

The Pfizer vaccine is an mRNA vaccine, which contains the genetic material to code for the spike protein. Once inside your cells, your body uses those instructions to make spike protein, again raising a protective immune response. COVID vaccines don’t give you the disease or give you a positive COVID test. Again, they don’t contain live viruses. They contain fragments of spike protein or instructions on how to make it.

Even if you could shed spike protein after vaccination, that wouldn’t be enough to cause an infection. For that, you need the entire virus, which the vaccines don’t contain. And the mRNA in the Pfizer and Moderna vaccines is very short-lived and is quickly degraded in our cells. Again, the mRNA wouldn’t be enough to cause an infection. It would need to be packaged inside a live virus, which our vaccines don’t contain.

Being Near To People Vaccinated Against Covid

What was claimed

You can get side effects of Covid-19 vaccines simply by being in close proximity to someone who has had the vaccine.

Our verdict

This is false. There is nothing in the Covid-19 vaccines used in the UK that could cause vaccine shedding.

Somesocialmediaposts claim that unvaccinated people can experience Covid-19 vaccine side effects, particularly issues with fertility, simply by being in close proximity to people who have had a vaccine.

This is not true. The three types of vaccine developed to stop SARS-CoV-2, the virus which causes Covid-19, do not contain materials that could lead to vaccine shedding. There is also no evidence that vaccines affect fertility.

Fears about vaccine shedding, especially in live attenuated vaccines, are based on viral shedding, the process by which cells of the body release viral particles and could therefore, theoretically, increase the risk of infecting others.

Live attenuated vaccines, often referred to simply as live vaccines, contain whole bacteria or viruses which have been weakened so they can stimulate an immune response but do not actually cause the disease in healthy people.

There are three Covid-19 vaccines currently approved for use in the UKPfizer/BioNTech, AstraZeneca-Oxford and Moderna. None of them use a live version of SARS-CoV-2, the virus that causes Covid-19.

Its absolutely ridiculous to suggest that there could be any shedding of anything from someone who’s had one of those vaccines.

    Which Vaccines Do Shed

    No, COVID Vaccine Shedding Is Not A Thing

    Its technically possible for any live-attenuated vaccine to shed. But in most instances, documented cases of this are rare.

    The oral polio vaccine is responsible for the most harmful infections related to vaccine shedding. The live-attenuated virus used in this vaccine can be shed from the body in feces.

    In very rare cases, the virus used in the OPV can mutate and become harmful, potentially leading to paralysis. In countries that still use the OPV, this is estimated to occur in 2 to 4 out of every million live births each year.

    Since the year 2000, the OPV is no longer licensed or available in the United States. Now, all polio vaccines given in the United States are inactivated vaccines.

    Other live-attenuated vaccines for which shedding has been documented include the:

    • Flu nasal spray vaccine: Shedding of the virus used in this vaccine is common, particularly in younger individuals, according to the . While transmission of these viruses can occur, its rare and not typically associated with symptoms.
    • Chickenpox vaccine: According to the , there have been reports of only 11 healthy vaccinated individuals worldwide spreading the chickenpox vaccine virus to 13 unvaccinated people.
    • Rotavirus vaccine: Rotavirus vaccine virus can be shed in feces for days after vaccination. An older in twins found that the vaccine virus could be transmitted to unvaccinated individuals, but wasnt associated with symptoms.
    • MMR vaccine: The rubella part of the MMR vaccine

    What Is Viral Shedding Anyway

    People can shed virus after a viral infection, such as SARS-CoV-2, the virus that causes COVID-19.

    If people are infected, they can shed virus via their respiratory secretions when they cough and sneeze. During the pandemic, thats why we socially distance, wear masks and stay at home if were sick. We can only infect someone if the virus is live.

    Read more:We don’t know for sure if coronavirus can spread through poo, but it’s possible

    Some vaccines for other diseases contain live viruses that have been weakened . Examples are vaccines against measles, rubella, mumps and herpes zoster .

    These train your body to mount an immune response with a version of the virus that isnt so dangerous.

    For example, with the very effective vaccine against herpes zoster , there is a very small risk the weakened virus can cause infection. However, this happened in less than 1% out of more than 20,000 people vaccinated over a ten-year period. The majority of people infected this way had a weakened immune system.

    How Shedding After A Vaccine Really Works

    Regular readers will know that a favorite antivaccine trope is to claim that live attenuated virus vaccines shed the virus and that that this attenuated virus is dangerous to those around them. This is a trope that existed long before the COVID-19 pandemic, and is being repurposed by antivaxxers now. Steve Novella has discussed viral shedding in the vaccinated as antivaxxers use it to spread fear of vaccines, but Im going to go through it as well.

    Basically, its the antivax answer to the observation that they are potential sources of infection and outbreaks. Its projection in which they try to convince you that it is the recently vaccinated, not the unvaccinated, who are a danger to the unvaccinated and vaccinated alike. Its long been very clear to me that the claim that children shed virus and are thus potential vectors for infection is important to antivaxxers because it allows them to portray others as equally, if not more so, the cause of outbreaks than their children, but is there anything to it? Regular readers can probably guess the answer to that question. The answer, of course, is that theres far less to the issue of virus shedding than meets the eye. As I mentioned above, virus shedding can only occur with live virus vaccines, such as the rotovirus vaccine, oral polio virus vaccines , or intranasal flu vaccines.

    We learn from the former article that these are the commonly given live virus vaccines:
