Asian countries with some of the world’s highest vaccination rates are rushing to expand booster shots as winter approaches and the coronavirus surges again through Europe.
After initially trailing other wealthy countries on vaccinations, several Asian nations have now overtaken them. As 2022 approaches and the new Omicron variant prompts alarm, they are calibrating their booster strategies at a time when the virus is crashing through highly vaccinated countries in Europe where boosters are not yet widely available.
The European Union’s public health agency recommended on Wednesday that all adults receive a booster shot, especially people over 40. On Thursday, its executive arm proposed that residents of the bloc will need booster shots to avoid tests or quarantines when traveling to other E.U. member states.
