Japan said international travellers showing proof of a Covid-19 vaccination with the Johnson & Johnson shot would be allowed in and be eligible for a shorter time in quarantine when border controls are eased next month.

The J&J shot, which has not been approved in Japan, will join a list of three other shots that have been approved by regulators as sufficient for non-residents to enter, after a nearly two-year ban on such travellers, Reuters reports.

The other approved vaccines on a list that the foreign ministry released are the ones developed by Pfizer Inc, Moderna Inc, and Astrazeneca Plc.
