The Mexican Ministry of Health has issued guidelines recommending that pregnant women refrain from receiving the measles vaccine. This recommendation is primarily based on the vaccine containing live attenuated viruses, which pose potential risks for transmission to the fetus via the umbilical cord. Ramiro López, the Undersecretary of Health Policies and Population Wellbeing, emphasized this aspect during a recent press conference, highlighting the importance of considering the safety of both the mother and the unborn child when making vaccination decisions.

In cases where a pregnant woman exhibits symptoms of measles, the authorities encourage seeking prompt medical attention either in hospitals or clinics for appropriate treatment rather than opting for vaccination. This caution extends beyond pregnant women; it also applies to individuals with weakened immune systems due to conditions such as chemotherapy, cancer treatments, or other illnesses. The health officials indicated that hospitals can provide alternative medications to help boost immunity for those who may be at risk.

The focus on the age group between 13 and 49 years for vaccination efforts stems from higher vulnerability within this demographic, as they are more likely to experience severe complications from measles. Highlighting the potential benefits of targeted vaccination strategies is crucial for public health, aiming to protect both individuals and the community while minimizing potential harms associated with vaccinating high-risk populations like pregnant women.
