Why the CDC recommends wearing masks indoors, even if you've been fully vaccinated

The reason public health officials are calling for more mask-wearing is that there is clear and mounting evidence that - though rare - breakthrough COVID-19 infections can occur in people who are fully vaccinated. This is particularly true with emerging variants of concern. The good news is that COVID-19 infection, if it does happen, is much less likely to lead to serious illness or death in vaccinated people.
