‘Delta a nasty one’: US to recommend Covid-19 vaccine boosters
- US facing renewed wave of infections fuelled by Delta variant
- Booster shot programme could start as early as September
Federal health officials have been actively looking at whether extra shots for the vaccinated would be needed as early as this fall, reviewing case numbers in the US as well as the situation in other countries such as Israel, where preliminary studies suggest the vaccine’s protection against serious illness dropped among those vaccinated in January.
An announcement on the US booster recommendation was expected as soon as this week, according to two people familiar with the matter.
Doses would only begin to be administered widely once the Food and Drug Administration formally approves the vaccines. That action was expected for the Pfizer shot in the coming weeks.
Last week, US health officials recommended boosters for some with weakened immune systems, citing their higher risk of catching the virus and evidence that the vaccines’ effectiveness waned over time.
The director of the National Institutes of Health, Dr Francis Collins, said on Sunday the US could decide in the next couple weeks whether to offer coronavirus booster shots to Americans this fall.
