– a month ahead of schedule, the Biden administration announced this week.
Moderna has signed a $1.74 billion federal contract to supply 66 million initial doses of the “bivalent” booster, which includes the original “ancestral” virus strain and elements of the Omicron BA.4 and BA.5 variants. Pfizer also announced a $3.2 billion U.S. agreement for another 105 million shots. Both vaccine suppliers have signed options to provide millions more boosters in the months ahead.
About 83.5% of Americans have received at least one COVID-19 shot, with 71.5% fully vaccinated with the initial series, 48% receiving one booster shot, and 31% two boosters, according to the CDC. With about 130,000 new COVID cases per day, and about 440 deaths, officials say the updated boosters may help rein in those figures by targeting the highly transmissible and widely circulating Omicron strains.
Federal health officials are still hammering out details of guidelines and recommendations of who should get the boosters, which are expected to come from the CDC and FDA. For now, authorities have decided not to expand eligibility for second boosters of the existing vaccines – now recommended only for adults over 50 and those 12 and older with immune deficiencies. Children 5 through 11 are advised to receive a single booster, 5 months after their initial vaccine series.
For a preview of what to expect from the CDC and FDA, this news organization spoke with Keri Althoff, PhD, an epidemiologist at Johns Hopkins University, Baltimore.
Q: Based on what we know now, who should be getting one of these new bivalent boosters?A: Of course, there is a process here regarding the specific recommendations, but it appears there will likely be a recommendation for all individuals to get this bivalent booster, similar to the first booster. And there will likely be a recommended time frame as to time since the last booster.
Right now, we have a recommendation for adults over the age of 50 or adults who are at higher risk for severe COVID-related illness [to get] a second booster. For them, there will probably be a timeline that says you should get the booster if you’re X amount of months or more from your second booster; or X amount of months or more from your first booster, if you’ve only had one.
Q: What about pregnant women or those being treated for chronic health conditions?A: I would imagine that once this bivalent booster becomes available, it will be recommended for all adults.
Q: And for children?A: That’s a good question. It’s something I have been digging into, [and] I think parents are really interested in this. Most kids, 5 and above, are supposed to be boosted with one shot right now, if they’re X amount of days from their primary vaccine series. Of course those 6 months to 4.99 years are not yet eligible [for boosters].
As a parent, I would love to see my children become eligible for the bivalent booster. It would be great if these boosters are conveying some additional protection that the kids could get access to before we send them off to school this fall. But there are questions as to whether or not that is going to happen.
