Japan is likely to achieve herd immunity to Covid-19 through mass inoculations only months after the planned Tokyo Olympics, even though it has locked in the biggest quantity of vaccines in Asia, Reuters reported quoting a London-based forecaster.

That would be a blow to Prime Minister Yoshihide Suga who has pledged to have enough shots for the populace by the middle of 2021, as it trails most major economies in starting Covid-19 inoculations.

“Japan looks to be quite late in the game,” Rasmus Bech Hansen, the founder of British research firm Airfinity, told Reuters. “They’re dependent on importing many [vaccines] from the US And at the moment, it doesn’t seem very likely they will get very large quantities of for instance, the Pfizer vaccine.”
