With Covid cases on the rise again as winter approaches, health officials widely encourage those eligible to get the recently updated booster shot as soon as possible.
“The revised boosters are similar to their now-retired predecessors, which were first made available about a year ago,” explains American Association of Retired Persons (AARP).
“However, instead of delivering a single set of instructions (called mRNA) that the body uses to build its own defence against the virus that causes Covid-19, they pass along two sets: one specific to the original strain of the coronavirus and one specific to subvariants of omicron.”
