COVID-19 Information

Vaccines & Boosters

The COVID-19 vaccine is a safe and effective way to prevent serious illness and death from the COVID-19 virus. Every COVID-19 vaccine is offered free of charge regardless of insurance status. All individuals 6 months and older are eligible to receive a COVID-19 vaccine.

On Sept. 1, 2022, the Centers for Disease Control and Prevention (CDC) recommended the use of the Pfizer-BioNTech and Moderna updated bivalent COVID-19 vaccine boosters.

Both updated bivalent boosters are formulated to combat the BA.4 and BA.5 sub variants of the Omicron variant. The Pfizer-BioNTech bivalent booster is available for individuals 12 years and older at least 2 months after receiving their most recent monovalent booster dose or completing their primary series. The Moderna bivalent booster is available for adults ages 18 years and older at least 2 months after receiving their most recent booster dose or completing their primary series.

You are up to date with your COVID-19 vaccines if you have completed a COVID-19 vaccine primary series and received the most recent booster dose recommended for you.

All Health Department locations within the Lord Fairfax Health District have walk-in hours for individuals to receive COVID-19 vaccinations or boosters. COVID-19 vaccine walk-in hours: 9:00 AM - 11:00 AM and 1:00 PM - 3:00 PM Monday thru Friday. No appointment is needed.
