"I've been vaccinated. Do I need to worry about variants?"
That depends on a few things — including your personal risk tolerance.
But first off, know that your vaccine is quite valuable. The COVID-19 vaccines are expected to be protective against the new virus variants, according to the World Health Organization.
Exactly how much the various vaccines protect against the delta variant — the newest form of the virus that the Centers for Disease Control and Prevention has dubbed a "variant of concern" — is still somewhat of a guessing game. But if you're fully vaccinated (two weeks after your second dose) the odds are highly favorable that you won't get a breakthrough COVID-19 infection, and even better that if you are one of the unfortunate few, you won't get a severe case.
