In Mexico, only 26.6% of children aged 12 to 35 months have complete vaccination schedules documented, including the triple viral vaccine (SRP), according to the 2022 National Health and Nutrition Survey (Ensanut). This situation has contributed to the resurgence of measles in the country, where 73.4% of children in this age group have not completed their vaccination series, raising serious concerns for public health and child safety.

The survey indicates that there are approximately 12 million children aged one to six years, which emphasizes the scope of the vaccination shortfall. The first dose of the SRP vaccine should be administered at 12 months of age; however, in 2022, only 61.8% of children under five received at least one documented dose, showing a considerable decline from 72.6% in 2021. This downward trend in vaccination coverage can lead to increased outbreaks of measles and other vaccine-preventable diseases.

The alarming statistics reveal not only the urgent need for intervention to improve vaccination coverage among young children but also the potential long-term implications for public health policy in Mexico. With an incomplete vaccination rate of over 73%, authorities are under pressure to reassess and enhance vaccination strategies to protect vulnerable populations and prevent further health crises as global trends point towards rising vaccine hesitancy amidst misinformation.
