U.S. health officials said in a White House press briefing Tuesday that COVID-19 vaccines will likely become a yearly occurrence, like the annual flu shot, unless a "dramatically" different variant of the virus emerges.
Why it matters: The officials said this likelihood was based on the new, updated bivalent booster shots authorized by the Centers for Disease Control and Prevention last week, which protects against the original strain of the virus and the currently circulating dominant strain.
