New COVID-19 booster vaccines expected to be available in Fairfax County this week

Most booster shots against COVID-19 were put on hold over Labor Day weekend, as Fairfax County prepares for newly authorized vaccines designed to target omicron variants of the coronavirus.

Appointments for the updated boosters are expected to be available through the county’s Vaccine Administration Management System (VAMS) by tomorrow (Wednesday), the Fairfax County Health Department confirmed to FFXnow.

Known as bivalent vaccines, the new shots from Pfizer and Moderna contain the original strain of COVID-19 as well as a component that can be found in the two most dominant omicron subvariants, BA.4 and BA.5, according to the Food and Drug Administration, which authorized the vaccines on Aug. 31.

As a result, the updated boosters will “provide better protection against COVID-19 caused by the omicron variant,” the FDA said.

However, as part of the new authorization, the emergency use authorizations for the existing Pfizer and Moderna boosters were suspended on Friday (Sept. 2). Both vaccines can still be used for the primary two-dose regimen, and the Pfizer vaccine can be used as a booster for kids aged 5 through 11.

For people 12 and older, though, the county health department ceased administering booster doses at its offices and clinic sites on Friday.

“We had a handful of booster appointments set for the past weekend and our Call Center team contacted these individuals to let them know that they could re-schedule appointments when the bivalent boosters arrived,” FCHD spokesperson Lucy Caldwell said.

The health department has ordered 12,900 Pfizer bivalent vaccines and 8,100 Moderna shots and “plans to begin vaccinating this week,” according to Caldwell.

Pfizer’s vaccine has been authorized for people aged 12 and older, and Moderna’s is for adults 18 and up. Eligibility for the doses begins at least two months after getting the primary vaccinations or the most recent booster.

Appointments for the updated boosters won’t be required, but they are recommended, given the limited initial supply. Shots will eventually become available at private medical offices, pharmacies and other locations in the community.

“We thank everyone for their patience,” Caldwell said.

The FDA also issued an emergency use authorization last week allowing adolescents aged 12 to 17 to get the Novavax Covid vaccine, which became available to adults last month. Regardless of age, everyone is still required to make an appointment to get that vaccine, since supplies are limited.
