What if I get COVID-19 during vaccination?

There is Three COVID-19 vaccines Currently used in the United States:

The mRNA vaccine is given as follows 2 times A single dose was found to lead to a fairly weak immune response. Adding a second dose enhances the immune response to the vaccine and helps protect it from COVID-19 infection.

For this reason, the mRNA vaccine provides some protection after a single dose, but nevertheless. COVID-19 (new coronavirus infection) Between doses.

The Clinical trials Both of these vaccines were evaluated for efficacy after a single dose. Let’s see what the data says.

Pfizer-BioNTech

In a clinical trial of the Pfizer-BioNTech vaccine, 39 vaccinated individuals were infected with COVID-19 between doses, compared with 82 in the placebo group.

Researchers have found that the vaccine that prevents COVID-19 is effective between the first and second doses of the vaccine. 52 percent..

This means that participants receiving the Pfizer-BioNTech vaccine are about half as likely to receive COVID-19 after a single dose as compared to participants receiving placebo injections.

modern

In a document submitted to the Food and Drug Administration (FDA), researchers analyzed a small group of volunteers who received only one Moderna vaccine or placebo. Within the first 14 days, 50.8% It was reported.

But over time, things change. In the larger clinical trial group, only 11 vaccinated individuals were infected with COVID-19 more than 2 weeks after the first dose, compared with 225 in the placebo group.

This corresponds to the vaccine efficacy of 95.2% It begins 2 weeks after the first dose.

If you are infected with COVID-19 during vaccination Centers for Disease Control and Prevention (CDC) It is advisable to delay the next dose until recovery from the illness.

There is no specific time to wait after recovering from COVID-19, but most doctors recommend waiting at least 2 weeks.

When you meet the CDC, you can get the following vaccines: Guidelines for stopping quarantine.. At the time of writing, these guidelines are as follows:

• stay at home. stay at home at least 5 days After symptoms begin or become positive COVID-19 test.. Wear a mask when you need to be around your family.
• Finish the separation. When you can end the separation depends on your particular situation.
  • If you have symptoms and have not had a fever for more than 24 hours, you can end the quarantine after a full 5 days or more. When Your other symptoms are starting to get better.
  • In the absence of symptoms, quarantine can be terminated at least 5 days after a positive COVID-19 test.
  • If the disease is severe or the immune system is weakened, it should be quarantined for at least 10 days. Always consult your doctor before leaving quarantine.
• Mask up. After 5 days of quarantine, continue to wear masks at home and in public for another 5 days. During this time, do not go to public places where you cannot wear a mask, such as restaurants and gyms.

These guidelines apply to everyone, regardless of vaccination status. Therefore, if you become infected with COVID-19 during vaccination, you can schedule a second dose after the end of the quarantine period.

If you miss the 3 or 4 week interval of vaccination depending on the quarantine period, there is no problem. In this situation, CDC recommendation Receive a second dose as close as possible to this window period. There is no need to restart the vaccine series.

It is still important to receive a second dose of the COVID-19 vaccine, even if you have to delay it because you were infected with COVID-19 between doses. This is because it is still unclear exactly how long the innate immunity to COVID-19 will last.

In fact, there is some new evidence that some individuals are infected with COVID-19. When If you have been vaccinated with COVID-19, your immunity may have improved. This is called hyperimmunity.

A January 2022 study I explored this concept. People infected with COVID-19 before or after vaccination compared to those who were just vaccinated antibody Widely neutralizes the virus.

The protection provided by the COVID-19 vaccine diminishes over time. Vaccines are still very effective in protecting you from serious illness, hospitalization, or death from COVID-19, but as your immune system weakens, you may become more susceptible to mild or moderate illness. there is.

For this reason, CDC recommendation Booster shots for everyone over 12 years old.

You can choose a different COVID-19 vaccine as a booster, but the timing of the booster depends on the vaccine you originally received.

• If you get the Pfizer-BioNTech or Moderna vaccine: Boosters can be obtained at least 5 months after the first two-dose vaccine series. Either of the two mRNA vaccines can be used as a booster.
• If you have been vaccinated with the J & J vaccine: Boosters can be obtained at least 2 months after the first single dose vaccine.
