[Evaluation of a meningococcal ACWY catch-up vaccination program for adolescents on Community of Madrid.]

OBJECTIVE In 2019 the Interterritorial Board of the Spanish National Health System approved the modification of the vaccination strategy against meningococcus. The objective of this study was to evaluate the meningococcal ACWY catch-up vaccination program in adolescents born in 2001 and 2002 in the Community of Madrid. METHODS Cross-sectional population-based study. Vaccine coverage was estimated and factors associated with vaccination were assessed using logistic regression models. RESULTS Vaccination coverage was 57.1% for those born in 2001 and 51.9% for those born in 2002. The probability of vaccination was higher in women (ORa=1.18), adolescents with chronic conditions (ORa=1.38), residents in rural areas (ORa=1.76) and in areas with lower socioeconomic level. Being born in 2002 (ORa=0.78) and abroad (ORa=0.35) were associated with a lower probability of vaccination. CONCLUSIONS Coverage is high compared to similar campaigns in other settings, although there is significant room for improvement, so our study can contribute to the design of strategies to optimize results.
