The Food and Drug Administration has laid out a road map for what Covid-19 vaccination may look like moving forward.
In a enlightening document published Monday, the FDA said the vaccines will probably need an annual update as the virus continues to evolve. The workings would select the Covid strain for the vaccine in the spring so the updated shots could roll out every September in meanwhile for a fall vaccination campaign.
Most people would receive one shot to restore their protection against the virus emotional forward, according to the briefing document. This would apply to people who have been exposed to the virus’s annul protein at least twice, either through vaccination or infection.
But older adults and people with compromised unsusceptible systems may need two doses, according to the proposed vaccination schedule. Young children who have received only one guess previously would also get two doses.
The FDA released the road map ahead of a meeting of the agency’s independent vaccine experts assigned for Thursday. The expert panel will vote on whether to make all Covid vaccines in the U.S. bivalent shots, meaning they shield against both the omicron BA.5 subvariant as well as the original strain of Covid discovered in Wuhan, China, in late 2019.
Currently, only Moderna’s and Pfizer’s booster dispenses target the omicron variant. If adopted, the primary series would also contain the omicron strain.
The proposed group for updating Covid vaccines resembles how the FDA selects flu shots every year. The agency said it could update and rollout the Covid vaccines without clinical details, which is also the case with the annual process to change the flu shot.
The Centers for Disease Control and Prevention on Thursday is also look for to provide more information about an investigation into what it has described as a “very unlikely” risk of stroke in elders who received Pfizer’s omicron booster.
The CDC received preliminary safety concern data from its Vaccine Safety Datalink belated last year. A subsequent review for four other major databases did not identify an increased risk for stroke, but the CDC search is ongoing.
