The coronavirus vaccination rollout for people under 65 in Japan should be carried out at the same time as those with underlying conditions to help speed up the process, the health minister said Sunday.

While those with underlying conditions will generally be given priority, "if we wait until everyone (with underlying conditions) has been vaccinated, we don't know when it will be completed," Health, Labor and Welfare Minister Norihisa Tamura said on a program aired by public broadcaster NHK.

Those who qualify to receive priority vaccinations will need to report to municipalities independently, as the government has no data available as to exactly how many people are eligible.
