Key Points

• In Île-de-France, vaccination coverage among infants subject to the mandatory vaccination requirements in effect since June 1, 2018, is high for vaccinations against diphtheria, tetanus, polio, pertussis, Haemophilus influenzae type b, hepatitis B, pneumococcus, and meningococcus C. However, coverage remains insufficient for the measles, mumps, and rubella (MMR) vaccine, with only 84.4% of infants receiving the second dose of this trivalent vaccine. Given the current circulation of the measles virus, only two-dose vaccination coverage of at least 95% is likely to interrupt transmission of the virus.

• 79% of infants born in 2023 in Île-de-France received at least one dose of the meningococcal B vaccine, representing a 23.9-point increase compared to the previous year.

• 40% of infants born in 2023 received at least one dose of the rotavirus vaccine in our region. Significant disparities between departments are observed for this vaccination, which has been recommended since 2023.

• Although vaccination coverage against meningococcal C has increased by 4 percentage points among adolescents, catch-up vaccination remains very insufficient among young people aged 15 to 19, with vaccination coverage at 50%.

• In Île-de-France, 46% of 15-year-old girls and 22% of 15-year-old boys have started their human papillomavirus (HPV) vaccination series. HPV vaccination coverage increased significantly in 2023, with a 6-point increase among girls and coverage that doubled among boys compared to 2022. HPV vaccination coverage remains, however, far from the 80% target set by the 10-year cancer control strategy for 2030.

• At the conclusion of the first phase of the human papillomavirus (HPV) vaccination campaign in middle schools, as of December 31, 2023, it is estimated that approximately 46% of girls and 35% of boys aged 12 (born in 2011, mostly in 7th grade) received at least one dose of the HPV vaccine in Île-de-France. These estimates account for vaccinations administered in middle schools and in private medical practices. A 16-point increase in vaccination coverage among girls and a 15-point increase among boys was observed between the start and end of the first phase of the campaign, though it is not yet possible to specify the exact portion of this increase directly attributable to the campaign.

• Vaccination coverage against influenza, COVID-19, and shingles remains insufficient among at-risk individuals: Less than 2% of people aged 65–74 are vaccinated against shingles. Influenza vaccination coverage is declining among people with risk factors, with low coverage among those aged 65–74 (45%). COVID-19 vaccination coverage was 31% among those aged 65 and older.
