Hello Jacques,
Currently, only immunocompromised people can receive a 4e dose, in accordance with the recommendations of the Advice on vaccine strategy. Their original full regimen already included three injections, not two. The sanitary pass will remain valid, even without 4e dose. The Scientific Council plans to extend this campaign to people over the age of 12 living in their environment.

If this possibility were to be extended, it would primarily concern the elderly, the most fragile and caregivers. It is possible that the youngest will be kept away from this new vaccination campaign. In Israel, where it is offered to people over 60, caregivers and immunocompromised people, “it is out of the question today to administer a fourth dose to people under 60”, recalled the immunologist Cyrille Cohen at Parisian.
Uncertain effectiveness
As for the effectiveness of this third reminder, it remains debated. As explained by Scientific Council in its opinion of January 19the experts are “awaiting solid scientific data” to determine the relevance of a 4e dose in people “old and frail”. The question of when this possible campaign would take place also arises: it should not start before March 2022.
