US government health advisers indicated that some Americans who received Moderna’s COVID-19 vaccine should get a half-dose booster to improve their protection against the virus.
The US Food and Drug Administration (FDA) advisory panel voted unanimously in favor of recommending a booster injection for older adults with other health problems, with employment, or with escalating life situations. your risk of getting COVID-19.
The recommendation is not binding, but it represents an important step toward expanding the booster campaign across the country for millions more Americans. Many of the people who received their first two doses of the Pfizer vaccine at least six months ago are already receiving a booster after the FDA authorized its use last month.
Regarding dosage, Moderna’s initial vaccine consists of two injections of 100 micrograms each. But Moderna says a single 50-microgram injection should suffice for a boost.
The agency convened its experts on Thursday and Friday to discuss who should receive the boosters and when they would be given to people who received the Moderna and Johnson & Johnson vaccines earlier this year.
The FDA will use the recommendations of its advisers to make the final decision for vaccine boosters for both companies. If approved, there is another hurdle: Next week, a panel convened by the Centers for Disease Control and Prevention (CDC) will offer more details on which sectors of the population should get the booster shot.
