WASHINGTON: United States health officials want to make COVID-19 vaccinations more like the annual flu shot.
The US Food and Drug Administration (FDA) on Monday (Jan 23) proposed a simplified approach for future vaccination efforts, allowing most adults and children to get a once-a-year shot to protect against the mutating virus.
This means that Americans would no longer have to keep track of how many shots they have received or how many months it has been since their last booster.
The proposal comes as boosters have become a hard sell. While more than 80 per cent of the US population has had at least one vaccine dose, only 16 per cent of those eligible have received the latest boosters authorised last August.
The FDA will ask its panel of outside vaccine experts to weigh in at a meeting on Thursday. The agency is expected to take their advice into consideration while deciding future vaccine requirements for manufacturers.
In documents posted online, FDA scientists said that many Americans now have “sufficient preexisting immunity” against the coronavirus because of vaccination, infection or a combination of the two.
That baseline of protection should be enough to move to an annual booster against the latest strains in circulation and make COVID-19 vaccinations more like the yearly flu shot, according to the agency.
For adults with weakened immune systems and very small children, a two-dose combination may be needed for protection. FDA scientists and vaccine companies would study vaccination, infection rates and other data to decide who should receive a single shot versus a two-dose series.
