The vaccine produced by this American company is already available in dozens of other countries. In the United States, on the other hand, only three anti-Covid vaccines were currently authorized: those with messenger RNA from Pfizer and Moderna, and that from Johnson & Johnson. But access to the latter has been limited due to an increased risk of serious thrombosis.
Two doses
The emergency authorization of the Novavax vaccine will “offer American adults who have not yet received a vaccine against Covid-19 another option”, welcomed in a press release Robert Califf, the head of the agency of the drugs (FDA).
Administered in two doses three weeks apart, it uses a more traditional technique than messenger RNA, which has been the target of many conspiracy theories, although it has been shown to be very safe. The Novavax vaccine contains a component of the virus that triggers an immune response, similar to the pertussis, meningococcal meningitis and hepatitis B vaccines.
“Have confidence”

The vaccination rate for the adult population is stagnating around 77% in the United States. The US government announced this week that it had purchased 3.2 million doses of the vaccine from Novavax, anticipating the FDA’s decision.
