The article delves into the common doubts surrounding measles vaccination in Mexico, where the measles vaccine is administered within the first months of life and is reinforced later. It poses a critical question: what happens if someone has already received two vaccinations? The focus is on the two types of measles vaccines available in Mexico: the triple viral and the double viral, which are administered based on age.

Dr. Tina Tan, the president of the Infectious Diseases Society of America (IDSA), states that receiving more than two doses of the measles vaccine is generally safe and most individuals do not encounter severe side effects. When side effects do occur, they are typically mild, including pain or swelling at the injection site, low fever, or a slight rash. The standard vaccination schedule includes two doses of the MMR (measles, mumps, and rubella) vaccine, which boasts an effectiveness rate of 97%. This high efficacy rate is significant in preventing outbreaks of the disease.

Moreover, a spokesperson from the U.S. Centers for Disease Control and Prevention (CDC) emphasizes that individuals who have received the two doses of the measles vaccine are well protected against the virus. However, the article aims to clarify misconceptions and provide reassurance regarding any potential concerns about receiving additional doses, highlighting the importance of vaccination not only for individual protection but also for community health and herd immunity against measles outbreaks.
