Key Points

• Vaccination coverage among infants subject to the mandatory vaccination requirements in effect since 2018 is high for vaccinations against diphtheria, tetanus, polio, pertussis, Haemophilus influenzae type b, hepatitis B, pneumococcal disease, and meningococcal disease C; however, coverage remains insufficient for the measles, mumps, and rubella (MMR) vaccine, with coverage of nearly 87% for the second dose of this vaccine. Given the current circulation of the measles virus, only a two-dose vaccination coverage of at least 95% is likely to interrupt transmission of the virus.

• Nearly 80% of infants born in 2023 received at least one dose of the meningococcal B vaccine, representing a 31-point increase compared to the previous year.

• 28% of infants born in 2023 received at least one dose of the rotavirus vaccine in the region. Significant regional disparities are observed for this vaccination, which has been recommended since 2023: ranging from 26% in Pas-de-Calais to 39% in Aisne.

• Although meningococcal C vaccination coverage has increased by 3 percentage points among adolescents, catch-up vaccination remains very insufficient among young people aged 15 to 19, with a vaccination coverage rate of nearly 59%.

• Nearly 61% of 15-year-old girls and 28% of 15-year-old boys have started their HPV vaccination series. HPV vaccination coverage (1 dose at age 15) increased significantly in 2023, with a 7-point increase among girls and coverage that doubled among boys compared to 2022. HPV coverage remains far from the 80% targets set in the 10-year cancer control strategy for 2030.

• As of December 31, 2023, at the conclusion of the first phase of the HPV vaccination campaign in middle school, it is estimated that approximately 65% of girls and 49% of boys aged 12 (born in 2011, mostly in 7th grade) have received at least one dose of the HPV vaccine. These estimates take into account vaccinations administered in middle schools and in the community. An increase of 18 percentage points among girls and 17 percentage points among boys in vaccination coverage was observed between the start and end of the first phase of the campaign, although it is not yet possible to specify the gain directly attributable to the campaign.

• Regional vaccination coverage against influenza, COVID-19, and shingles remains insufficient among at-risk individuals. Flu vaccination coverage is declining among people with risk factors, with low coverage among those aged 65–74 (52%). COVID-19 vaccination coverage was approximately 31% among those aged 65 and older. For shingles, 2% of people aged 65–74 are vaccinated.
