Health workers from the West couldn't help out in other countries due to lockdowns and restrictions. So they turned to help at home. But what is their role in lower resource countries moving forward?
The largest number of deaths have come in the United States, Brazil, Mexico, India and the United Kingdom. The pandemic death toll reached 1 million in September 2020 and 2 million in January.
In the U.S., more than 1 out of 5 residents is fully vaccinated against COVID-19. But elsewhere in the world, vaccination rates are much lower. Some poor nations have yet to receive a single dose.
No vaccine is 100% effective. Though so-called "breakthrough" COVID cases are rare, the virus is circulating widely. What's a vaccinated person to do? And ... not do?

A vast network of professional vaccine skeptics on social media has been waiting for a development like the Johnson & Johnson pause. Now experts say they will milk it for all it's worth and more.
COVID-19 vaccines are highly effective but don't always provide perfect protection. Some vaccinated people later exposed to the virus still get sick. Why and how often that happens is under study.
