After months of toil and criticism, Japan’s once-sluggish vaccine campaign has reached a turning point as a growing majority of the population becomes inoculated and the country prepares to roll out booster shots from December.

What remains is to inoculate children ages 11 and younger, and to begin administering booster shots to medical personnel, the elderly and those with compromised immune systems.

The country has gone full circle as it enters the final stages of its initial rollout of the first and second doses of the vaccine, while simultaneously gearing up to begin distributing a third.
