Coronavirus: US FDA approves updated Covid-19 vaccines to increase protection this autumn
- The FDA decision opens the newest vaccines from Moderna and Pfizer and its partner BioNTech to most Americans
- The Centres for Disease Control and Prevention are set to issue recommendations on Tuesday on who most needs the updated vaccinations
The US approved updated Covid-19 vaccines on Monday, hoping to rev up protection against the latest coronavirus strains and halt any surge this autumn and winter.
The Food and Drug Administration (FDA) decision opens the newest vaccines from Moderna and Pfizer and its partner BioNTech to most Americans even if they have never had a coronavirus vaccination. It is part of a shift to treat autumn updates of the Covid-19 vaccine much like getting a yearly flu vaccination.
Covid-19 hospitalisations have been rising since late summer although – thanks to some lasting immunity from prior vaccinations and infections – not nearly as much as this time last year.
But protection wanes over time and the coronavirus continually churns out new variants that can dodge prior immunity. It has been a year since the last time the vaccines were tweaked.
