Key Points

• Vaccination coverage rates among infants subject to the mandatory vaccination requirements in effect since 2018 could not be calculated based on the DCIR-SNDS data from the health insurance system for vaccinations against diphtheria, tetanus, polio, pertussis, Haemophilus influenzae type b, hepatitis B, pneumococcus, and meningococcus C, because the Territorial Collectivity of French Guiana, through the PMI (Maternal and Child Health Centers), administers a significant proportion of these vaccines, which are provided free of charge and thus not recorded in the DCIR-SNDS. Vaccination coverage is, however, estimated for vaccines recommended in 2023:

• 28.9% of infants born in 2023 received at least one dose of the meningococcal B vaccine, representing a 15-point increase compared to the previous year.

• 3.4% of infants born in 2023 received at least one dose of the rotavirus vaccine in the region.

• Although vaccination coverage against meningococcal C has increased by 3.8 percentage points among adolescents, catch-up vaccination remains very insufficient among young people aged 15 to 19 in 2023, with a vaccination coverage rate of 32.5%.

• 29.3% of 15-year-old girls and 8.6% of 15-year-old boys began their HPV vaccination series. HPV vaccination coverage increased significantly in 2023, with a 4.4-point increase among girls and coverage that nearly 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 25% of girls and 18% of boys aged 12 (born in 2011, mostly 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 was observed among both girls and boys 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. Flu vaccination coverage is declining among people with risk factors, with low coverage among those aged 65–74 (12.9%). COVID-19 vaccination coverage was also low, at 2.4% among those aged 65 and older. Less than 1% of people aged 65–74 were vaccinated against shingles.
