Singapore starts booster shots

Singapore has kicked off a booster vaccination program against the coronavirus amid the spread of the highly transmissible Delta variant.

Health officials say among the eligible recipients are seniors aged 60 and older who were double vaccinated at least six months ago, and people with suppressed immune systems.

The city state is one of the most inoculated countries in the world with more than 80 percent of its residents fully vaccinated. But community infections have been on the rise. Authorities reported 832 such cases on Tuesday.
The figure was below 50 in mid-August.

Government officials say the booster is necessary to maintain a high level of protection as the immune systems of elderly people may weaken over time and they could become seriously ill.
