COVID-19 Vaccination Questions and Answers

With more and more people are getting their COVID-19 vaccine, we are also getting more and more questions about those COVID-19 vaccinations.

What to Know About COVID-19 Vaccination

In general, folks should know that:

  • the Pfizer COVID-19 vaccine is given on a two dose schedule, with the second dose being given 21 days after the first dose
  • the Moderna COVID-19 vaccine is given on a two dose schedule, with the second dose being given 28 days after the first dose
  • the Janssen COVID-19 vaccine is given as one dose only – there is no second dose!
  • yes, you can and should get vaccinated even if you have already had a natural COVID-19 infection

What other questions are coming up?

Over 247 million doses of COVID vaccines have been administered in the United States.
As we are meeting out goals for vaccinating and protecting folks, vaccination rates are slowing down.


Probably because rates of COVID are also going down, so people don’t see an urgent need to get vaccinated and protected. They don’t realize that the pandemic isn’t over yet and as we are seeing in other countries, cases could surge again if more people don’t get vaccinated.

COVID-19 Vaccination Questions and Answers

In addition to myths and misinformation about the COVID-19 vaccines, other things to know about COVID-19 vaccinations include that:

  • Can you mix and match the COVID-19 vaccines? No. The second dose should be of the same type as the first dose of COVID-19 vaccine. That being said, if you unintentionally get a mismatched schedule of doses, then you would not need another dose.
  • Do you have to restart the series if you are late for your second dose? No. In fact, the second dose of Pfizer-BioNTech and Moderna COVID-19 vaccines may be administered up to 6 weeks (42 days) after the first dose. And while you should try and get your second dose as close as possible to stay on schedule, you do not have to restart the series if you are late getting your second dose.
  • Can you get your second COVID-19 vaccine dose early? While you should stay on schedule, as with most other vaccines, there is a 4 day grace period for the COVID-19 vaccination schedule, so if you received your second dose 1 to 4 days early, then it won’t need to be repeated.
  • How long do you have to wait after actually having COVID-19 before getting vaccinated? Technically, you only have to wait until you are out of your isolation period and are no longer contagious. However, since you could be immune for at least three months (and probably much longer), you might wait and allow others to get vaccinated and protected before you get your vaccine if you have already had COVID-19. And even if you have had your first dose and then test positive, you can still get your second dose.
  • How long do you have to wait after getting your COVID-19 vaccine before getting other vaccines? While the original advice was 14 days, you no longer have to wait to get other vaccines coadminstered with your COVID vaccine.
  • You should avoid taking acetaminophen and ibuprofen before you get your COVID-19 vaccine.
  • Will getting a COVID-19 vaccine affect the results of SARS-CoV-2 viral tests (PCR or antigen tests)? No.
  • Will getting a COVID-19 vaccine affect the results of SARS-CoV-2 antibody tests? Yes, but only if the antibody titer test is assessing IgM and/or IgG to spike proteins. Antibody tests to the nucleocapsid protein will only detect past infection, but not vaccination.
  • Can you get COVID-19 from a COVID-19 vaccine? No. These are not live virus vaccines, so it is not possible to actually become infected from the vaccine.
  • Do the COVID-19 vaccines cause shedding? No. The currently approved COVID-19 vaccines do not actually contain any viral particles, so can’t cause you to shed. So yes, it is safe to be around someone who has recently had their COVID-19 vaccine.
  • Which COVID-19 vaccine should you get? The first one that is made available to you! There is no real evidence that any one of these vaccines is better than the others, so get the first COVID-19 vaccine that is available to you and don’t wait for a specific vaccine.
  • Do the currently approved COVID-19 vaccines work against mutated strains. Yes. So far, our vaccine seem to work against COVID-19 variants.
  • When will COVID-19 vaccines be available for younger children? The current estimate is that younger children might start getting vaccinated this fall, as clinical trials start to ramp up in this age group. Teens can get vaccinated now with the Pfizer COVID vaccine.
  • What do I do if I have a mild or moderate adverse event from the COVID-19 vaccine? Most adverse events are mild or moderate (headache, pain, fever, etc.), go away in a few days, and can be treated with rest, pain relievers, and cold compresses, etc.
  • What do I do if I have a severe adverse event from the COVID-19 vaccine? If you have a severe adverse event, especially a severe allergic reaction or blood clotting, then you should seek immediate medical attention.
  • How do you report adverse events to the COVID-19 vaccine? In addition to entering your side effects during your daily v-safe surveys, you can and should report any adverse event to the COVID-19 vaccine to VAERS.
  • COVID arm is a delayed local reaction.
  • COVID-19 vaccines can cause some recipients to develop inflammatory unilateral axillary adenopathy, which can show up on a mammogram.
  • You can likely get a COVID-19 vaccine if you are immunocompromised.
  • When can I get my shot? COVID-19 vaccines are being distributed everywhere and are no longer based on prioritization within risk groups. So you should be able to get a vaccine as long as you are at least 12 years old and don’t have a contraindication.
  • Why will I still need to wear a mask after I get my COVID-19 vaccines? It’s mostly because the vaccine is not 100% effective, so you should continue to wear a mask and practice social distancing in high risk situations until the pandemic is over.

Still thinking about whether or not to get vaccinated and protected?

I was thankful and excited when I was able to get my COVID-19 vaccine!
