The Food and Drug Administration (FDA) has laid out a roadmap for what COVID-19 vaccination will look like in the future.
In a briefing paper released Monday, the FDA said vaccines will likely want an annual update as the virus continues to evolve. The company would choose the Covid strain for the vaccine in the spring so that updated vaccines can be rolled out. every September in time for an autumn vaccination campaign.
Most other people would receive an injection to repair their virus coverage in the future, according to the report. This would apply to other people who have been exposed to the virus’ spike protein at least twice, either by vaccination or infection.
But older adults and others with weakened immune systems may need two doses, depending on the proposed vaccination schedule. Young people who have only had one shot before will also receive two doses.
The FDA released the roadmap ahead of an assembly of vaccine experts independent of the agency scheduled for Thursday. The panel will vote on whether to manufacture all covid vaccines in the U. S. They are also opposed to the U. S. subvariant omicron BA. 5 as the original Covid strain discovered in Wuhan, China, in late 2019.
Currently, only booster doses from Moderna and Pfizer target the omicron variant. If adopted, the number one series would also include the omicron strain.
The proposed formula for updating covid vaccines is similar to how the FDA selects flu vaccines by year. The company said it may only update and roll out covid vaccines without clinical data, which is also the case with the annual flu vaccine replacement process.
Also expected Thursday is the Centers for Disease Control and Prevention to provide more data on an investigation into what they described as a “very unlikely” threat of stroke in older adults who won Pfizer’s omicron booster.
CDC obtained initial information about protection issues from its expired vaccine protection information link last year. An upcoming review of four other databases did not identify an increased threat of stroke, but the CDC investigation is ongoing.
