The vaccine provides a blueprint to the bodys cells for how to protect against COVID, Chin-Hong explained and a booster shot acts as a "reminder" to the immune system. And also like with the flu vaccine, drug manufacturers would update the annual shot to match the dominant variant that year like the latest bivalent COVID booster was updated to target both the original coronavirus strain and the dominant omicron variants.

A genetic trait that harkens back to the pandemic's past, similar to what is known as the delta mutation," appears to allow the subvariants "to escape pre-existing immunity from vaccination and prior infection, especially if you were infected in the omicron wave," said Dr. Wesley Long, a pathologist at Houston Methodist in Texas.
