Taro Kono, the Japanese minister in charge of the vaccine rollout, promised Sunday a timely administering of booster shots for the coronavirus, as the nation aims to fully vaccinate its population by October or November.
Japan is aiming for 80 per cent vaccination levels, Kono said on a nationally broadcast Fuji TV show.
A digital system for proof of vaccination will be available later this year, he added.
Japan has lagged among developed nations on vaccinations, with its fully vaccinated now at about 43 per cent. Hospitals are getting swamped, and more than 118,000 people infected with the coronavirus are waiting at home, according to the health ministry. Japan has recorded about 15,800 COVID-related deaths.
