COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and dying. As with other vaccine-preventable diseases, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations, including recommended boosters.
COVID-19 Boosters are classified in two categories: updated and original.
The updated boosters are called “updated” because they protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer and Moderna, have developed updated COVID-19 boosters.
Updated COVID-19 boosters became available on:
September 2, 2022, for people aged 12 years and older
October 12, 2022, for people aged 5–11 years
December 9, 2022, for children aged 6 months–4 years who completed the Moderna COVID-19 vaccine primary series.
Previous boosters are called “original” because they were designed to protect against the original virus that causes COVID-19. They also provide some protection against Omicron, but not as much as the updated boosters.
Types of Vaccines we offer and dosing:
Primary series for
12 years of age & older
The vaccine is administered as a primary series of 2 doses that are given
3 weeks apart.

3rd Dose FOR IMMUNOCOMPROMISED
For individuals with certain kinds of immunocompromise, a third primary series dose may be administered at least 28 days after the second dose.
Pfizer-BioNTech COVID-19 Vaccine, Bivalent (Original and Omicron BA.4/BA.5)* was designed as a response to increasing rates of infection caused by certain COVID-19 variants—in particular the Omicron variant BA.4/BA.5.
*Pfizer-BioNTech COVID-19 Vaccine, Bivalent (Original and Omicron BA.4/BA.5) is referred to as
Pfizer-BioNTech COVID-19 Vaccine, Bivalent.

When Are You Up to Date?
You are up to date with your COVID-19 vaccines when you have completed a COVID-19 vaccine primary series and got the most recent booster dose recommended for you by CDC.
If you have completed your primary series—but are not yet eligible for a booster—you are also considered up to date.
If you become ill with COVID-19 after you received all COVID-19 vaccine doses recommended for you, you are also considered up to date. You do not need to be revaccinated or receive an additional booster.
COVID-19 vaccine recommendations are based on three things:
The vaccine you first received, and
The length of time since your last dose
Getting Vaccines If You Had or Currently Have COVID-19
If you recently had COVID-19, you still need to stay up to date with your vaccines, but you may consider delaying your next vaccine dose (whether a primary dose or booster) by 3 months from:
when your symptoms started.
Or, if you had no symptoms, when you first received a positive test.
Reinfection is less likely in the weeks to months after infection. However, certain factors could be reasons to get a vaccine sooner rather than later, such as:
personal risk of severe disease,
or risk of disease in a loved one or close contact,
local COVID-19 Community Level,
and the most common COVID-19 variant currently causing illness.
