Covid vaccination is the best way to help avoid serious illness, hospitalization and possibly even death from Covid.
Covid vaccines are generally well-tolerated and can give you peace of mind that you're helping to protect yourself and your loved ones.
What vaccines are available for adults?
A protein-based vaccine — made by Novavax
mRNA vaccines — made by Pfizer-BioNTech and Moderna
Current CDC guidelines state that people ages 5 and older should get 1 updated vaccine at least 2 months after their last dose of any previous Covid vaccine.
An updated vaccine is a 2023–2024 Covid vaccine that was approved or authorized for use during or after September 2023.
Can I mix and match vaccines?
Yes! Your next Covid vaccine doesn’t have to be the same type as your last one. So if you’ve already had an mRNA vaccine, you can get boosted with a protein-based vaccine. And vice versa.
| If you choose this vaccine … | and are previously vaccinated, get: | and are not previously vaccinated, get: |
|---|---|---|
| Pfizer | 1 updated dose | 1 updated dose |
| Moderna | 1 updated dose | 1 updated dose |
| Novavax | 1 updated dose | 1 updated dose and a 2nd dose 8 weeks later |
If you are moderately or severely immunocompromised, talk to your healthcare provider about additional vaccine doses you may need.
