WASHINGTON — Top U.S. health officials announced a plan Wednesday to begin offering COVID-19 booster shots to Americans starting Sept. 20, with the scheduling of the additional shot to be based on when a person was fully vaccinated.
Dr. Vivek Murthy, the U.S. surgeon general, told reporters Wednesday that recent data makes clear that while the current COVID-19 vaccines have been highly effective against severe disease, hospitalization and death, the protection against mild and moderate disease has appeared to decrease over time.
“This is likely due to both waning immunity and the strength of the widespread delta variant,” Murthy said, adding that health officials are concerned that the decline in immunity could reduce protection against severe disease and death in the months ahead.
The new booster rollout plan is subject to formal authorization from the Food and Drug Administration and the Centers for Disease Control and Prevention’s vaccine panel.
Those agencies will hold public meetings before the booster rollout can begin. But officials said they were detailing the booster plan ahead of those meetings in part to give state and local health officials time to prepare for another wave of vaccination logistics.
During a Wednesday morning Michigan Department of Health and Human Services (DHHS) update on rising COVID-19 cases in Michigan with reporters, officials were asked if the state had an ample amount of vaccines to meet the need for booster shots.
“We are certainly watching very closely what the FDA and the CDC are saying. We are prepared and currently have ample supply of vaccines to be able to supply a third dose, if people need it, both for the immunocompromised that was just announced this past Friday, but also if the general public needs a third booster dose — which I believe the CDC has said will begin Sept. 20,” said Dr. Joneigh Khaldun, chief medical executive and DHHS chief deputy director for health. “So we are prepared.”
As the Advance previously reported, Gov. Gretchen Whitmer issued Friday an executive directive to state departments and agencies “to move as quickly as possible to administer an additional dose to vulnerable individuals in long-term care facilities within the state.” On Monday, Detroit Major Mike Duggan announced the TCF Center would reopen as a vaccination site for people who have compromised immune systems to receive a third dose.
The more than 13 million Americans who received the one-dose shot from Johnson & Johnson may also need boosters, but will not yet be eligible.
Federal health officials said they are awaiting data from J&J in the next few weeks before urging additional doses. The J&J shot wasn’t approved until March, so those who received it will not hit eight months past inoculation until November.
State and local health officials again under pressure
The plan for offering a third shot puts yet another layer of pressure on state and local health departments that have carried out the massive vaccination campaign.
Those officials are still seeking to boost vaccination rates that have lagged in certain regions amid skepticism and misinformation. Meanwhile, vaccine manufacturers are expected this fall to seek approval for administering shots to children under 12, who so far have not been eligible.
During Wednesday’s news briefing, Dr. Rochelle Walensky, the CDC director, cited several new studies that tracked vaccine effectiveness, including among New Yorkers across age groups and another following case counts from nursing homes.
Those studies have shown that protection against severe infection has held up but not against milder infections, she said, adding that other countries, such as Israel, also are starting to see “worsening outcomes.”
“In the context of all of these studies, different cohorts, different settings across the country, and our international colleagues, we’ve made the decision to plan for these booster doses,” Walensky said.
The booster shots will be available at roughly 80,000 sites nationally, including 40,000 local pharmacies. As with the other COVID-19 shots, the boosters will be free of charge.
The CDC had already approved a third COVID-19 shot for some immunocompromised individuals, who may not have received strong protection from the initial doses of the vaccine.
While the booster plan does not specifically mention other categories of individuals to receive a priority for boosters, the initial vaccine rollout did put certain groups first in line. So the first individuals to hit eight months after their second shot should be those in the earliest priority categories, such as health care workers and nursing home residents.
