Key Points

• Among infants born in 2018 or later who are subject to the expanded vaccination mandate, vaccination coverage still needs to improve to achieve the goal of herd immunity:

  • 88.4% for the vaccine against diphtheria, tetanus, polio, pertussis, Haemophilus influenzae type b, and hepatitis B by age 21 months;

  • 87.5% for the pneumococcal vaccine at 21 months of age;

  • 86.1% for the meningococcal C vaccine at 21 months of age (5 percentage points lower than in France).

• Insufficient MMR vaccination coverage (77.1% with an up-to-date vaccination schedule at 33 months), increasing the risk of outbreaks.

• Increasing vaccination coverage among adolescents and young adults against meningococcal C since 2015, but herd immunity has not yet been achieved to provide effective protection for unvaccinated individuals.

• Increase in HPV vaccination coverage—1 dose—among 15-year-old girls. Conversely, there is a significant gap in HPV vaccination coverage among 16-year-old boys, with only 1% having a complete vaccination schedule (2 doses).

• A decline of more than 10 percentage points in vaccination uptake among the population of Réunion between 2014 and 2021 (Public Health France-DROM Barometer), whereas in metropolitan regions, uptake increased between 2016 and 2021.
