COVID-19 Vaccination | COVID-19 Booster Shots

Am I eligible for a booster shot?

If you meet the following criteria, you are eligible for a booster shot.

  • If you are 18+ and received your Moderna vaccination series (both shots) at least five months ago.
  • If you are 12+ and received your Pfizer vaccination series (both shots) at least five months ago.
  • If you are 18+ and received your Johnson & Johnson vaccine two or more months ago. If this is the case for you, getting a Pfizer or Moderna booster will give you added protection.

If you meet any of the following criteria, you are not yet eligible for a booster shot.

  • If you are currently COVID positive, please wait for symptoms to resolve before getting boosted.
  • If you received your Pfizer or Moderna vaccination series fewer than five months ago, you are not yet eligible for your booster dose.
  • If you had COVID and received monoclonal antibody treatment, you are not eligible for a booster until 90 days after that treatment. 

The CDC has expanded eligibility for an additional booster dose for certain individuals who may be at higher risk of severe outcomes from COVID-19:

  • People over the age of 50 can now get an additional booster 4 months after their prior dose. This is especially important for those 65 and older and those 50 and older with underlying medical conditions that increase their risk for severe disease from COVID-19. 
  • Individuals 12 years of age and older who are immunocompromised are eligible for a second booster dose of the Pfizer-BioNTech COVID-19 vaccine at least 4 months after the first booster dose.
  • Individuals 18 years of age and older who are immunocompromised are eligible for a second booster dose of the Moderna COVID-19 vaccine at least 4 months after the first booster dose. 

Read the latest guidance from the CDC.

Which booster shot should I get?

Eligible individuals may choose between the Pfizer and Moderna vaccines for their booster dose. The CDC recommendations do allow for mixing and matching, so if you got Pfizer previously, you can get a Moderna booster or vice versa. Due to concerns around possible cardiovascular side effects, the CDC is not recommending Johnson & Johnson boosters at this time. Consult with your medical provider if you have any questions about the best option for you.

Where can I get my booster shot?

Please visit our COVID-19 vaccine page to find a site nearest you. 

How do I notify Loyola when I have gotten my booster?

Once you have gotten your booster shot, you should report your status on Loyola’s Public Health Portal

What if I lost my CDC white card?

We will give you a new card with your booster dose.

When am I considered fully vaccinated vs. up to date on vaccines?

A person is fully vaccinated two weeks after receiving all recommended doses in their primary series of COVID-19 vaccine. Up to date means a person has received all recommended doses in their primary series of COVID-19 vaccine, and one booster dose when eligible. Getting a second booster dose is not necessary to be considered up to date at this time. If you received your booster shot less than 7 days prior to being exposed, then you will be considered "not up-to-date on COVID-19 vaccinations" and will need to follow the CDC's guidelines for quarantine. Please reach out to covid@loyno.edu immediately regarding potential exposure.
