a shortened time for the booster dose?

Could the time between the last dose and the vaccine booster go down from five months to three months? To counter the arrival of the Omicron variant, the hypothesis is at the heart of the debates of the health authorities. Today, to take your booster dose, you have to wait between five and seven months, but the interval could be reduced. “Why not if we ever have to act, it must be a good idea”, testifies a retiree coming to be vaccinated.

A deadline shortened to three months, a new strategy approved a few days ago by the European Medicines Agency. Some French scientists also say they are in favor. “After three months, the protection against infections with Omicron decreases significantly and it becomes insufficient”, reports Professor Anne-Claude Crémieux, infectious disease specialist at Saint-Louis hospital. “If you want to protect yourself very quickly against a pathogen, you have to make a maximum of doses in a minimum of time”, adds Professor Jean-Daniel Lelièvre, immunologist and expert at the Haute Autorité de Santé.
