As concern grows over the omicron variant of the coronavirus, Prime Minister Fumio Kishida announced that Japan will shorten the timeline for booster shots for 31 million medical workers and elderly people.

Unveiling the country’s beefed-up COVID-19 measures, the prime minister said Friday that the interval between second shots and booster shots, which was originally set for at least eight months, will be six months for health care workers and those living in nursing homes.

Starting in February, seniors who aren't living in nursing facilities will also be able to receive their third shots seven months after their second jabs, Kishida said.
