Vaccination pass: receive your booster dose without waiting by choosing a Pfizer or Moderna vaccine

Vaccination with a booster dose has proven in recent months its remarkable effectiveness against severe forms and long-lasting Covid, regardless of the messenger RNA vaccine used. In a context where major changes to the vaccination pass are coming into force and where several hundred thousand people risk losing the benefit of their pass from February 15, the ARS Hauts-de-France and the vaccination centers continue to mobilize all available resources for the benefit of the inhabitants of the region. Until at least the end of February, the Pfizer and Moderna vaccines are both once again accessible for people over 30 in vaccination centers and in town, for booster doses, first or second injections.

When should you receive your booster dose?

To continue to be protectedpeople over the age of 18 may receive a booster dose:

  • from 3 months after the last injection of the initial diagram;
  • as early as 3 months after infection for those who contracted Covid more than 15 days after a first injection (without previous Covid contamination).

People who contracted Covid-19 after the initial vaccination schedule do not need to take the booster dose to be fully protected. However, these may be requested to travel to certain countries.

For 12-17 year olds, the booster vaccination is started 6 months after the last injection or infection. They absolutely must keep their certificate of reinstatement. Note however that this reminder may be required for trips abroad, including in Europe.

Vaccination pass: people vaccinated before October 15 must have received their reminder

For the record, the rules for obtaining the vaccination pass for those over 18 change from February 15. Thus, it will be necessary to have received the booster vaccine within 4 months after the last injection or infection. People with a complete vaccination schedule completed before October 15 must therefore have received their booster on February 15 to continue to benefit from their vaccination pass.

People who have contracted Covid-19 after the initial vaccination schedule can activate their recovery certificate or their positive test on the TousAntiCovid application to continue to benefit from the vaccination pass.

Vaccination close to home everywhere in Hauts-de-France

Vaccination is possible in many places to facilitate access to as many people as possible:

  • in one of the 138 Covid vaccination centers. The centers remain open on extended hours to allow vaccinations in the evening or on weekends. List of centers available on
  • at a pharmacy or from your doctor, nurse, midwife or dentist;
  • through occupational medicine.

All of these actors welcome you now for a primary vaccination or a booster dose with Pfizer and Moderna messenger RNA vaccinesdepending on the individual stocks of each vaccination site.

Mobile operations are also offered in addition to this permanent offer with the creation of ephemeral centers in many villages and towns.

Moderna and Pfizer, two effective, safe and interchangeable messenger RNA vaccines

In its opinion of 09/30, the Vaccine Strategy Guidance Council recommends “that the two messenger RNA vaccines be used for the booster. (…) The two mRNA vaccines have proven their effectiveness in protecting the population against SARS-CoV2. The Moderna vaccine induces slightly higher neutralizing antibody production and protection against infection than the Pfizer vaccine”. The Haute Autorité de Santé for its part recalled in its opinion of 8/11 that “several studies conducted in real conditions of use tend to show a slightly higher vaccine efficacy for Spikevax® (Moderna) compared to Comirnaty® (Pfizer) whose effectiveness is already very good, confirming the interest of Spikevax®, in particular in people at risk of a severe form of Covid-19. »

These two vaccines, which use the same technology, can be used alternately without risk: one can for example have received two first doses of Pfizer vaccine and receive a booster dose in Moderna.

As a precaution, the HAS has decided to favor the Pfizer vaccine for those under 30, insofar as the two messenger RNA vaccines are available. Indeed, if the Moderna and Pfizer vaccines have a very good tolerance, a nuance concerns however those under 30 years old: very rare cases (about 1/10,000) of inflammation of the heart muscle, most of the time transient and without gravity , were observed before this age with the Moderna vaccine. This could be explained by the fact that the RNA dosage of the Moderna vaccine was higher than that of the Pfizer vaccine. This difference in dosage could also explain a more lasting efficacy over time with the Moderna vaccine compared to the Pfizer vaccine.

Note that as part of the recall campaign, the dosage of the Moderna vaccine has been reduced by half (50 microg of messenger RNA, instead of 100 for the first and second injections), a rate sufficient to effectively boost the immune system.

In accordance with these recommendations, the Pfizer vaccine is therefore prioritized in Hauts-de-France for people under 30 years of age.
