Can You Carry Covid After Getting The Vaccine

Good Question: Can You Give Covid

5 things NOT TO DO after getting the COVID-19 vaccine

CHARLOTTE, N.C. – Weve been getting a lot of Good Questions about the vaccine from you.

So weve been taking some time each night to answer them.

Tonights Good Question comes from Scott.

Can you give COVID to someone in your household just because you got the vaccination?

Its important to know the COVID vaccine does not give you COVID.

So you wont spread the virus to someone in your household just because you got the shot.

However, you could spread the virus to someone in your household after you get vaccinated because you could be exposed to COVID somewhere else.

The vaccines protect you from getting severely ill, but experts say you could still carry the virus and spread it to someone else.

Its a little unclear even if youve been vaccinated that maybe you could transmit it to someone else, so just because youre vaccinated doesnt mean that you dont have to abide by the other standards, said Dr. Marc Moss, director of critical care at UC Health in Denver. If we abide by the other standards and get vaccinated this will all be behind us.

Health leaders say, even after you get vaccinated, wear a mask, socially distance yourself from others and wash your hands often. Its going to take some time to get to that herd immunity.

If you have a Good Question, send it to us. Well try to get you an answer.

When Youve Been Fully Vaccinated

How to Protect Yourself and Others

NOTICE: FDA has granted full approval for Pfizer-BioNTech COVID-19 Vaccine. CDCs Advisory Committee on Immunization Practices is meeting on Monday, August 30, 2021, to discuss its updated recommendation for this vaccine.

  • If you are not fully vaccinated and aged 2 or older, you should wear a mask in indoor public places.
  • In general, you do not need to wear a mask in outdoor settings.
  • In areas with high numbers of COVID-19 cases, consider wearing a mask in crowded outdoor settings and for activities with close contact with others who are not fully vaccinated.
  • People who have a condition or are taking medications that weaken their immune system may not be fully protected even if they are fully vaccinated. They should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.
  • If you are fully vaccinated, to maximize protection from the Delta variant and prevent possibly spreading it to others, wear a mask indoors in public if you are in an area of substantial or high transmission.
  • If you are fully vaccinated, see When Youve Been Fully Vaccinated.
  • band aid light icon If you havent been vaccinated yet, find a vaccine.

    COVID-19 vaccines are effective at protecting you from getting sick. Based on what we know about COVID-19 vaccines, people who have been fully vaccinated can do things that they had stopped doing because of the pandemic.

    What Efficacy Rates Really Mean

    You’ve probably heard about each vaccine’s efficacy rate. In their clinical trials, Pfizer-BioNTech’s and Moderna’s two-shot vaccines had an efficacy rate of about 95 percent, while the Johnson & Johnson single-dose vaccine had a 72 percent efficacy rate in the U.S.

    If a vaccine’s efficacy rate is 95 percent, you might assume that 5 out of every 100 people vaccinated people will get sick. But that’s not how the math works, says Anna Wald, an infectious disease physician and epidemiologist at the University of Washington School of Medicine.

    The actual percentage of vaccinated people who got COVID-19 in both the Pfizer and Moderna clinical trials was far smaller just around 0.4 percent.

    Efficacy is actually calculated by comparing people in a trial who got the vaccine to people who got the placebo, Wald says. So if you received the Pfizer-BioNTech or Moderna vaccine, whatever your chance was before, it’s now 95 percent less, Wald explains.

    There are two more things to know about those efficacy rates. First, none of the trial participants who received any of the authorized vaccines died of COVID-19. In other words, when it comes to what’s most important preventing death the vaccines were 100 percent effective in the trials.

    Can A Vaccinated Person Spread Coronavirus

    Immunologists expect vaccines that protect against viral illnesses to also reduce transmission of the virus after vaccination. But its actually tricky to figure out for sure if vaccinated people are not spreading the germ.

    COVID-19 poses a particular challenge because people with asymptomatic and pre-symptomatic infections can spread the disease and insufficient contact tracing and testing mean those without symptoms are rarely detected. Some scientists estimate that the number of asymptomatic COVID-19 infections in the overall population could be 3 to 20 times higher than the number of confirmed cases. Research suggests that undocumented cases of COVID-19 in people who either were asymptomatic or experienced very mild disease could be responsible for up to 86% of all infections, though other studies contradict the high estimates.

    In one study, the CDC tested volunteer health care personnel and other front-line workers at eight U.S. locations for SARS-CoV-2 infections weekly for three months, regardless of symptoms or vaccination status. The researchers found that fully immunized participants were 25 times less likely to test positive for COVID-19 than were those who were unvaccinated. Findings like this imply that if vaccinated people are so well protected from getting infected at all, they are also unlikely to spread the virus. But without contact tracing to track transmission in a larger population, its impossible to know if the assumption is true.

    You Shouldn’t Be Surprised

    Can You Get COVID

    Tori Gleason, 41, got her shots in December and January. As a healthcare provider herself , she knew from the get-go that she still had a chance of becoming infected.

    Gleason felt “like crud” for five days and says her case was probably moderate rather than mild. She was happy she’d been vaccinated.

    “I really believe had I not been vaccinated, they would be planning my funeral,” says Gleason. “It really underscores for me the necessary nature of getting vaccinated.”

    In clinical trials, the Moderna and Pfizer mRNA vaccines were a whopping 95 percent effective at preventing illness, especially severe illness. They’re “spectacularly effective,” confirms Dr. Schaffner.

    But they’re still not 100 percent. Compare that to the annual flu shot, which hovers around 50 percent and, like all vaccines, also has breakthrough infections.

    Clinical trials look at generally healthy people who are not necessarily representative of the “real” world.

    “They exclude people who don’t have normal immune systems or who are on immunosuppressant drugs,” says S. Wesley Long, MD, PhD, medical director of diagnostic microbiology at Houston Methodist. “You’re trying to determine the best conditions under which the vaccine will work.”

    Once the vaccines get to the general population, the equation can change.

    You May Or May Not Have The Delta Variant

    Neither Gleason nor Frederking knows if they had the Delta variant, which now causes most Covid-19 cases in the United States.

    The existing Covid vaccines are effective against Delta, but the variant spreads so easily that it likely is resulting in more breakthrough infections.

    “Delta is that it’s so incredibly contagious it’s running through unvaccinated people, and there will be spillover into people who are vaccinated,” says Dr. Schaffner.

    Breakthrough Cases And Delta: Background

    Until recently, scientists were unsure whether fully vaccinated people who became infected with COVID-19 could transmit it to others. But the CDC report released in late July made it clear that some vaccinated people can get Delta in a breakthrough infectionand may be contagious.

    The CDC added that breakthrough infections occur in only a small proportion of vaccinated people and of the breakthrough infections, transmission by the vaccinated appears to only be a small part of overall spread of the virus. But the CDC says it does not yet have data on the likelihood of asymptomatic spread among vaccinated people.

    So, where does that leave us?

    What we do know, says Dr. Meyer, is that there is less circulating virus in the community as a result of vaccination. When we look at vaccinations compared to cases on a population levelwe see that as the number of people vaccinated rises, the number of cases decreases, she says. This is likely due to the fact that people who are vaccinated are not becoming infected as often, but also that they are not forward-transmitting the virus as often.

    But more research is needed. The CDC says that “studies are underway to understand the level and duration of transmissibility from Delta vaccine breakthrough infections.”

    Are These New Mrna Vaccines Safe

    Yes. Both the Pfizer and Moderna vaccines were approved for emergency use by the Federal Drug Administration . As part of the approval process, independent experts reviewed the data from approximately 33,000 individuals who received either vaccine and concluded that side effects were relatively mild and short-lived and the known and potential benefits of avoiding serious disease from coronavirus outweighed the risk. Since these vaccines have been approved, roughly 63 million doses have been administered and the vaccines continue to be monitored for safety.

    Merck Says Its Antiviral Pill Reduces Covid

    How soon after COVID-19 infection can you get the vaccine?

    It’s likely that people who have been vaccinated clear the infectious virus from the body faster. A previous study from Singapore had found that although levels of the virus were initially the same in those infected with the delta variant regardless of vaccine status, by day seven, levels of the virus dropped quickly in those who were vaccinated, which may reduce the ability to spread illness.

    There is emerging evidence that even though cycle threshold values may be the same regardless of vaccination status, people who are vaccinated may have less infectious virus in their bodies, potentially reducing transmission. Richterman pointed to a recent pre-print from China that found a large reduction in transmission in those who had received two doses of vaccine, compared to the unvaccinated.

    Vaccines have the ability to prevent transmission of the virus in two ways, he said. The first is by preventing infection altogether. The other is by reducing the amount of infectious virus should somebody get sick.

    People who have been vaccinated will have immune systems at the ready that can coat the virus in antibodies much more quickly than unvaccinated people who have to build up an immune response, Richterman said.

    Vaccinated People Are Much Less Likely To Pass On Sars

    Early evidence from testing in animals, where researchers can directly study transmission, suggested immunisation with COVID-19 vaccines could prevent animals passing on the virus.

    But animals are not people, and the scientific community has been waiting for more conclusive studies in humans.

    In April, Public Health England reported the results of a large study of COVID-19 transmission involving more than 365 000 households with a mix of vaccinated and unvaccinated members.

    It found immunisation with either the Pfizer or AstraZeneca vaccine reduced the chance of onward virus transmission by 40-60%. This means that if someone became infected after being vaccinated, they were only around half as likely to pass their infection on to others compared to infected people who werent vaccinated.

    One study from Israel, which leads the world in coronavirus vaccinations, gives some clues about whats behind this reduced transmission. Researchers identified nearly 5 000 cases of breakthrough infection in previously vaccinated people, and determined how much virus was present in their nose swabs. Compared to unvaccinated people, the amount of virus detected was significantly lower in those who got vaccinated.

    More virus in the nose has been linked to greater infectiousness and increased risks of onward transmission.

    So How Effective Are Our Vaccines

    Preliminary data from the United Kingdom shows after your first dose of either Pfizer or AstraZeneca, youre 33% less likely than an unvaccinated person to contract the Delta variant.

    Two weeks after your second dose, this rises to 60% for AstraZeneca and 88% for Pfizer. This data is for any form of COVID-19, from mild to severe.

    But when you look at how much the vaccines reduce your risk of developing severe illness that requires hospitalisation, the coverage is high for both. Pfizer and Astrazeneca vaccines are 96% and 92% effective in preventing Delta variant hospitalisations.

    What Does Fully Vaccinated Mean

    According to CDC guidelines, you are fully vaccinated when it has been:

    • Two weeks after your second dose in a two-dose series, such as the Pfizer or Moderna vaccines.
    • Two weeks after a single dose of the Johnson & Johnson vaccine. However, data from clinical trials are clear that there is further improvement four weeks after the single-shot vaccine, especially for preventing severe COVID-19 or having asymptomatic infection. For this reason, Johns Hopkins Medicine recommends four weeks after the single-dose vaccine to be considered fully vaccinated.

    If you dont meet these requirements, you are not fully vaccinated.

    What We Know About Vaccine Breakthrough Infections

    Yes, you can still get infected with Covid
    • Breakthrough infections are expected. COVID-19 vaccines are effective at preventing most infections. However, like most vaccines, they are not 100% effective.
    • Fully vaccinated people with a breakthrough infection are less likely to develop serious illness than those who are unvaccinated and get COVID-19.
    • Even when fully vaccinated people develop symptoms, they tend to be less severe symptoms than in unvaccinated people. This means they are much less likely to be hospitalized or die than people who are not vaccinated.
    • People who get vaccine breakthrough infections can be contagious.

    CDC is collecting data on vaccine breakthrough infections and closely monitors the safety and effectiveness of all Food and Drug Administration -authorized COVID-19 vaccines. Because vaccines are not 100% effective, as the number of people who are fully vaccinated goes up, the number of breakthrough infections will also increase. However, the risk of infection remains much higher for unvaccinated than vaccinated people. Vaccines remain effective in protecting most people from COVID-19 infection and its complications.

    What Can You Do

    Youre considered fully vaccinated against COVID-19 two weeks after youve received either a single-dose vaccine, like Johnson & Johnson, or the second dose of a two-dose vaccine like Pfizer or Moderna.

    • Once youre fully vaccinated, you can feel safer doing the things you love. In outdoor settings and indoor settings in areas of low or moderate community transmission, if you are fully vaccinated, you can feel safer engaging in social situations without wearing a mask or practicing physical distancing.
    • You do not need to quarantine if you have close contact with someone with COVID-19.

    Covid Vaccines Dont Contain Live Virus To Shed

    However, none of the COVID vaccines approved for use anywhere around the world so far use live virus.

    Instead, they use other technologies to train our bodies to recognise 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 dont give you the disease or give you a positive COVID test. Again, they dont contain live virus. They contain fragments of spike protein or the instructions on how to make it.

    Even if you could shed spike protein after vaccination, that wouldnt be enough to cause an infection. For that you need the entire virus, which the vaccines dont contain.

    And the mRNA in the Pfizer and Moderna vaccines is very short-lived, and is quickly degraded in our cells. Again, the mRNA wouldnt be enough to cause an infection. It would need to be packaged inside a live virus, which our vaccines dont contain.

    Fully Vaccinated Less Likely To Pass Covid

    One question many people who are fully vaccinated for COVID-19 have is whether they can transmit the virus to someone who isnt vaccinated.

    For this to happen, it would mean the fully vaccinated person was asymptomatic. That term means being infected with the virus without ever knowing it.

    While the COVID-19 vaccines have provided an opportunity to slow the spread of the virus, scientists are trying to learn just how much the vaccines can prevent transmission from occurring.

    The good news is that data from the U.S. Centers for Disease Control and Prevention shows while COVID-19 infections do occur in fully vaccinated people, these instances appear to be exceptionally rare.

    We do not have conclusive proof. But more and more studies and real-world evidence points to fully vaccinated people, who are not immunocompromised, are less likely to transmit the virus if they become infected, said Brian Laird, PharmD, manager of Pharmacy Operations at OSF HealthCare Heart of Mary Medical Center in Urbana, Illinois.

    Once You Are Fully Vaccinated What Can And Cant You Do

    Can you take pain relievers after getting the COVID-19 vaccine?

    Once vaccinated, CU Boulder faculty, staff and students should continue to follow campus health and safety guidelines as they pertain to masks, physical distancing, etc.

    However, within groups of those who have been vaccinated , it is entirely reasonable to relax some of those pre-vaccine precautions. For example, a small indoor gathering without masks would be a low-risk activity when amongst a group of fully vaccinated individuals. Visiting family members who are also vaccinated would be another reasonable activityand one that we are all longing for.
