Covid-19: soon a new booster dose for the most fragile?

According to the HAS, it will be necessary to administer a new booster dose of vaccine against Covid-19 to the most fragile people and to those over 65 in the fall. I subscribe for 1€ for the 1st month

The French National Authority for Health recommends a reminder of the anti-Covid vaccine in the fall for the most vulnerable people. risk of serious forms, in particular people aged 65 and over, as well as immunocompromised people and their entourage, in a notice made public on Wednesday. The “most likely” evolution scenario of the health crisis is, in the eyes of the HAS, that of a “lesser” impact of the circulation of the virus, although “still active”, “thanks to a lasting immunity and sufficient to limit serious forms and deaths”.

For “reasons of mobilization and logistics”, the HAS suggests coupling this new vaccination campaign against Covid-19 with that against influenza. The HAS also recommends “considering the vaccination of health professionals in particular with regard to future data on vaccine efficacy against asymptomatic forms of the disease”. The type of vaccine to be favored for each category of population will, if necessary, be specified later, once new anti-Covid vaccines, targeting for example several variants at the same time, are authorized in France.

It is now up to the government to decide whether or not to follow the HAS recommendation, which it is not obliged to do. If she felt that “the hardest part is behind us” for the Covid-19 epidemic, the new Minister of Health Brigitte Bourguignon called on Wednesday for “vigilance” in the face of a possible return or “a small outbreak” in autumn. At this stage, the Borne government invites the “most fragile people to continue to have barrier gestures, protect themselves, get vaccinated”, she added on RTL, during her first interview in her new role.

Three scenarios for the evolution of the epidemic

To define its vaccine recommendations, the HAS worked from the three scenarios described by the World Health Organization on the circulation of Sars-CoV-2 in France during the coming months, from the most optimistic to the most pessimistic. “Even if the current data seems to show that the epidemic is stabilizing in France, it is highly likely that the circulation of the virus will periodically re-intensify,” she observes.

In the scenario deemed most likely, “the incidence and the number of severe cases are decoupled, which would lead to less and less severe epidemic waves”. But “periodic transmission peaks could occur due to the increase in the proportion of people with waning immunity, making it necessary to periodically administer a booster dose of vaccination for those most at risk of form.” severe”, details the HAS.

The HAS wants to anticipate the arrival of new variants

These transmission peaks could follow a pattern of periodic epidemic outbreaks, she adds. However, given the “many uncertainties” that persist on the evolution of the epidemic (possible emergence of new variants, etc.), the HAS does not exclude having to change its recommendations. “It is therefore necessary to be ready to anticipate the pessimistic scenario for which a large-scale vaccination campaign should be quickly organized,” she warns. Sub-lineages (BA.4 and BA.5) of the Omicron variant are currently under surveillance, suspected to be more transmissible but do not seem, for the moment, to be more severe.

According to the latest figures from health authorities, France recorded some 32,000 cases on Tuesday, an average of 22,579 daily cases over seven days. A month ago, the seven-day average was over 76,000.
