Guanajuato health officials are reinforcing guidance for pregnant women regarding measles prevention, emphasizing that the measles vaccine is contraindicated during pregnancy. However, the Secretaría de Salud de Guanajuato stresses that proactive steps can significantly reduce the risk of exposure to the virus, protecting both mother and developing child. This guidance comes as part of ongoing efforts to maintain control of measles across the state’s 46 municipalities, as reported February 12, 2026.
The cornerstone of protection is ensuring vaccination is up-to-date before becoming pregnant. If a woman is not currently vaccinated against measles, officials recommend receiving the vaccine prior to conception to establish immunity. Beyond individual vaccination status, encouraging vaccination among close contacts is also crucial in minimizing potential exposure. Measles is highly contagious, spreading through respiratory droplets produced by coughing or sneezing, making preventative measures particularly significant for vulnerable populations.
Vaccinations During Pregnancy: What is Safe?
Whereas the measles vaccine is not administered during pregnancy, several other vaccinations are considered safe and even recommended to protect both mother and baby. The Tdap vaccine (tetanus, diphtheria, and acellular pertussis) is strongly advised, beginning at 20 weeks of gestation, ideally between weeks 27 and 36. This vaccine provides crucial protection to the newborn against pertussis, also known as whooping cough.
Influenza and COVID-19 vaccines are also recommended throughout pregnancy. The influenza vaccine helps prevent severe complications from the flu for both mother and baby and can be received during any trimester. Similarly, the COVID-19 vaccine reduces the risk of severe illness and death in pregnant individuals and is recommended across all trimesters. These recommendations align with broader public health strategies to safeguard vulnerable populations.
Understanding Measles and Vaccination Schedules
The Secretaría de Salud emphasizes the importance of reviewing vaccination records and ensuring a complete immunization schedule, including the measles vaccine, before pregnancy. For children, the first dose of the measles vaccine is recommended at 12 months, with boosters at 18 months and 6 years of age for those born before July 2020. Individuals between 10 and 49 years old who lack prior vaccination or have an incomplete schedule should also receive the vaccine. Information on vaccination sites in Guanajuato is available online, with ongoing vaccination campaigns throughout February.
Measles is characterized by symptoms including fever, nasal congestion, red or irritated eyes, small spots inside the mouth, and a rash that begins on the face and spreads throughout the body. Left untreated, measles can lead to serious complications, particularly in children and individuals with weakened immune systems. The state’s ongoing surveillance system continues to monitor for potential outbreaks in coordination with federal health authorities.
For pregnant women with questions or concerns about vaccinations, the Secretaría de Salud encourages a visit to the Centros de Salud de la Gente for personalized medical guidance. Prioritizing preventative care and staying informed are key to a healthy pregnancy and a protected future for both mother and child.
