Covid-19. Is there a need for a booster dose for people already infected and first vaccinated?

“Having had Covid-19 and having only received one injection of the vaccine, can I have a second and how long do I have to leave between the two? “, asks Jacques, a reader from Diémoz (Isère).

Yes, you can receive a booster dose, which will therefore be a second injection for you.

“We can have a booster dose from the moment we are part of the target audiences and have received a complete vaccination schedule, whether with one or two doses”, explains the Ministry of Health.

Who is concerned ?

The High Authority for Health (HAS) already recommended at the end of August a booster dose six months after the last injection of the initial regimen for residents of nursing homes and USLDs, people over 65 living at home, people with very high risk of severe form. And also, people with comorbidity (s).

For people with severe immunosuppression, “The administration of the booster dose can be carried out within a period of less than 6 months (but at least 3 months), once it is judged by the medical team that it would improve the response immune “, specifies the government, on its site.

The HAS issued a new opinion on October 5, extending the scope of the people affected by this booster dose: now also eligible health professionals, all employees in the health sector and the medico-social sector, home helpers intervening with vulnerable people, medical transport professionals, as well as firefighters and people close to immunocompromised persons, only for adults over 18 years of age.

A new dose of Pfizer / BioNTech

What vaccine do we then receive in the second or third dose? “The booster shots are only carried out with the Pfizer / BioNTech vaccine, regardless of the vaccine used previously”, indicates the Ministry of Health, on its site.

The High Authority for Health recommends for the moment to use exclusively Pfizer’s vaccine and to wait for an opinion from the European Medicines Agency before using the Moderna vaccine for the booster injection.

What timeframe?

The booster dose is injected six months after the last injection. Six months after the second dose or in your case six months after your single dose.

The only exception is for people vaccinated with Janssen, a single dose vaccine, the booster dose must be injected 4 weeks after the injection of the single dose.
