Vaccinating with the third dose or the fifth? What is known about boosters

Omicron is spreading rapidly around the world and setting new records so high that we couldn't even imagine: more than 200,000 patients in France, more than a million in the United States. Omicron can even bypass existing immunity after vaccination or coronavirus disease, and this is the main problem of the new variant.

Another problem is that the vaccines stop working after a few months. So now the question in the world is that artificial immunity must be supported by booster vaccination.
