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, pneumococcus, and meningococcus C; however, coverage remains insufficient for the measles, mumps, and rubella (MMR) vaccine, with a coverage rate of 78.1% 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.

• 79.5% of infants born in 2023 received at least one dose of the meningococcal B vaccine, representing an increase of 1.3 percentage points compared to the previous year.

• 15% of infants born in 2023 received at least one dose of the rotavirus vaccine in Réunion.

• Although meningococcal C vaccination coverage has increased by 4 percentage points among adolescents, catch-up vaccination remains very insufficient among 15- to 19-year-olds, with a coverage rate of 59.2%.

• 24.4% of 15-year-old girls and 16.4% of 15-year-old boys began their HPV vaccination series. HPV vaccination coverage increased significantly in 2023, with a 5.3-point increase among girls and coverage that doubled among boys compared to 2022. HPV coverage remains far from the 80% target set in the 10-year cancer control strategy for 2030.

• At the conclusion of the first phase of the HPV vaccination campaign in middle schools, as of December 31, 2023, it is estimated that approximately 27% of girls and 16% of boys aged 12 (born in 2011, mostly enrolled in 7th grade) received at least one dose of the HPV vaccine. These estimates account for vaccinations administered in middle schools and in the community. A 10-point increase in vaccination coverage among girls and a 9-point increase among boys 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.

• Vaccination coverage against influenza, COVID-19, and shingles remains insufficient among at-risk individuals. Influenza vaccination coverage is declining among people with risk factors, with very low coverage among those aged 65–74 in Réunion (1.9%). COVID-19 vaccination coverage was only 1.9% among those aged 65 and older. Less than 2% of people aged 65–74 are vaccinated against shingles.
