The data also seem to increasingly show that natural infection leads to similar immunity to vaccination (previously it was not very clear), though the impact of variants and how it affects natural immunity is not well established yet.
This is good for limiting future outbreaks of the disease.
In any case, vaccinated people should understand it is essential for
others to become vaccinated (or infected) for their own vaccines to be fully effective. This is just common sense, of course. Until then, wearing masks indoors when the status of any individual is unknown is a good idea.
