An updated booster shot of COVID-19 vaccine is just around the corner. Today the FDA authorized updated booster vaccines for emergency use, but there are still a few steps left in
the approval process. Expert panels will review the applications from Pfizer and Moderna for these new booster vaccines at the end of this week and if they decide to recommend
them, the updated Omicron-specific boosters could be available late next week.
Nothing is ever final until the experts weigh in and the CDC makes its recommendations and issues new guidance. But in anticipation of an updated booster, here is what we know so
far:
The new booster shot will target Omicron variants and the original strain of COVID-19.
The updated COVID booster works like the annual flu shot. In the same way that the flu shot targets the expected flu strains for each upcoming season, this new COVID booster shot
will specifically target the Omicron BA.4 and BA.5 variants that are spreading widely. It will also target the original strain of COVID-19 that is in the current COVID-19 vaccine. It’s
called a “bi-valent” vaccine, which means that it targets two strains of a virus.
The new booster vaccines have the same basic ingredients as the current vaccine, but with an updated spike protein.
The updated part of the vaccine will be a little change in the spike protein that’s used to tailor it to the new Omicron variants. Otherwise, the basic ingredients are the same as the
COVID-19 vaccine that many millions of people have already received.
The soonest we could expect to offer the new booster is the weekend of September 9.
The applications will be reviewed by the CDC’s independent expert panel on September 1, and if they recommend the vaccines, then the CDC will make the final determinations
regarding the use of these boosters. In addition, an independent panel from the Western states will do a review. It could take a few more days for CDC recommendations and
guidance to be ready. If the CDC recommends the vaccines, doses will start to ship to the states after Labor Day.
The very earliest we could expect to have the new booster doses available at our vaccination sites at the Auburn Outlet Collection Mall would be the weekend of September 9th.
However, delays in shipping are possible, so it could be later. Vaccination providers will also need time to update their processes according to new CDC guidance for the booster, so
vaccination sites may vary in when they are able to start offering the new booster.
The vaccines are for people 12 years and older (but we are waiting to confirm who will be eligible)
Both Pfizer and Moderna have produced updated booster vaccines. Pfizer’s updated booster vaccine is for people 12 years and older. Moderna’s is for people 18 years and older.
However, it’s possible that in the review process, the expert panels or the CDC could decide that the new boosters should be prioritized for a specific age group or using some other
criteria. We won’t know until these expert groups deliberate.
You need to have your first COVID-19 vaccination series before you can get the updated booster shot.
These vaccines are only for booster doses, not for the 2-dose primary series.
You can get the updated booster shot at many locations in King County.
Public Health vaccination site at the Auburn Outlet Collection Mall will have both the Pfizer and the Moderna updated boosters once they have finished the approval process. Other
healthcare providers have also ordered new boosters and will offer them to non-members (though some may only offer them to members in the first week or two), including Kaiser
Permanente, UWMedicine, HealthPoint, SeaMar, Snoqualmie Valley Hospital, and ICHS. Pharmacies may also have the updated booster but check before going about availability.
