How effective is the booster vaccine?

The booster dose restores an immune response to the Omicron variant.

According to the opinion of the Scientific Council of December 16, 2021, the booster dose (2nd or 3rd dose) makes it possible to restore an immune response to the Omicron variant. It protects, probably at a good level, against the occurrence of severe and serious forms but only partially protects against infection with the Omicron variant. The first estimates of real-life vaccine efficacy have documented protection against symptomatic forms of infection with the Omicron variant of SARS-CoV-2 increasing from 80% 1-2 months to 34% 4 months after the second dose of a Pfizer vaccine, to rise to 75% two weeks after a booster dose. According to the Haute Autorité de Santé, the booster dose makes it possible to raise vaccine efficacy on cases of infection and severe forms. “The observed real-life efficacy data for a booster dose of the Comirnaty® vaccine given first in people 60 years of age or older vaccinated with two doses at least five months previously show a decrease the risk of infection by Covid-19 (…), 11.3 times lower cases of infections and cases of severe forms 19.5 times lower among people who had a booster dose than among those who did not. The effectiveness of the 3rd dose is observed in a short delay (very strong immunological response in a few days, clinically significant protection clearly shown from day 7) specified the Covid Scientific Council in an Opinion of November 22, 2021. The administration of a booster dose would also decrease the viral load and in fact, probably the contagiousness people developing an infection with SARS-CoV-2.

Vaccines from Pfizer and Moderna have received an extension of their marketing authorization for the recall, from the European Medicines Agency (EMA). Moderna obtained an extension of indication on October 25 for the administration of a booster dose of 50 mcg (half dose) in people aged 18 years and over. “Spikevax® (Moderna) and Comirnaty® from Pfizer are two safe and effective vaccines, but studies show a slight superiority of Spikevax® in terms of efficacy and lower risks of myocarditis for Comirnaty®, especially for people under the age of 30″ indicates the HAS in an Opinion of November 8, 2021. The HAS recommends as follows:

For those under 30: to do his booster dose with the Comirnaty® vaccine (Pfizer). “In the population under 30 years of age, the risk of myocarditis appears approximately 5 times lower for the Comirnaty® vaccine from Pfizer compared to the Spikevax® vaccine from Moderna (100 µg) in 12-29 year olds“, specifies the HAS in its press release.

For those over 30: to do their booster dose with the Pfizer or Moderna vaccine. “This is particularly interesting for people at risk of a severe form of Covid-19” notes the HAS which recommends the administration of a half-dose for the booster (50 µg of RNA instead of 100 in primary vaccination).

When an mRNA vaccine (Moderna and Pfizer) cannot be used, HAS authorizes, in a press release dated January 14, 2022, the administration of Janssen as a booster dose. “The Janssen vaccine can be offered to people over 55, even if they have received two doses of mRNA vaccines as a primary vaccination. Below 55, it can only be used as a booster only in exceptional circumstances, within the framework of a shared medical decision which provides clear information on the risks associated with this vaccine”, details the HAS.
