In its opinion, the High Authority of Health also recommends targeting people with comorbidities who increase the risk of serious forms of Covid-19.
After analysing the available data, the High Authority of Health clarified on Tuesday, August 24, 2021 the populations eligible for a vaccine booster dose against Covid-19.
For example, it offers a booster dose with a messenger RNA vaccine for people 65 years of age and older, as well as for people with comorbidities that increase the risk of severe forms of Covid-19.
This booster dose should be administered after a period of at least 6 months following complete primary vaccination.
“Recent studies suggest a reduction in the effectiveness of all vaccines, especially for the delta variant. This decrease in protection mainly concerns infection and symptomatic forms. There is also a slight decrease in efficacy on severe forms that remain well covered overall by vaccines. The decline is not only affecting seniors and populations at risk of severe forms, but they remain the most affected.”
Opinion delivered by the High Authority on 24 August 2021
Residents of the Ehpads
On August 12, 2021, the Ministry of Solidarity and Health had already confirmed the implementation of a vaccination recall campaign starting in mid-September to:
- Ehpad and Long-Term Care Unit (LTU) residents;
- People over the age of 80 living at home and those at very high risk of severe Covid-19;
- Immunocompromised persons.
On 18 August, the High Authority of Health was asked whether this recall campaign should be extended to other populations and whether it was likely that a vaccine recall in the general population would eventually be necessary.
