Questions and answers on the third dose: Those who have had AstraZeneca will benefit from the change of vaccines

Who can take the third dose?

People over 40, 5 months after the second dose. Healthcare personnel. Who got vaccinated with the Johnson & Johnson single-dose. Fragile patients. Immunosuppressed people: in the latter case there is no question of booster after the first vaccination cycle (the one consisting of the first two doses), but of completion of the vaccination cycle, because the first two injections are not sufficient to generate an immune response.
