With the arrival of the variant Omicron, you might be tempted to wait for a variant or an Omicron-specific booster to get your booster shot.
Another good reason you should not wait to get your booster is that most of the variant-specific boosters are still in the trial phase and most tests are still done on animals such as mice (7), hamsters (8), or on macaques (3).
It might take some time before we get a variant-specific booster that is providing better protection than the current boosters are offering.
