Japan's top government spokesman, Katsunobu Kato, has said there is not enough data yet to actively promote the mixed use of Covid-19 vaccines, and that further information is needed before reaching any decision on the matter, reports Reuters.
The comment comes after Taro Kono, minister in charge of Japan's vaccination programme, said on Sunday that Japan is looking into the possibility of mixing shots of AstraZeneca Plc's Covid-19 vaccine with those developed by other drugmakers in a bid to speed up its vaccine rollout.
