Babies who don’t get their first round of vaccines on time at 2 months of age are much less likely to get vaccinated against measles, mumps, and rubella by age 2, according to a new study that suggests pediatricians may have a narrow window in which to persuade parents to follow the recommended childhood vaccination schedule.
The study, published Friday in JAMA Network Open, reports that in the post-Covid-19 pandemic period, babies who didn’t get their shots on time at 2 months — the age at which the Centers for Disease Control and Prevention recommends babies get vaccines against a host of diseases — were more than seven times more likely not to receive their first measles, mumps, and rubella (MMR) shot by age 2, which is months later than when that shot is supposed to be given. Babies are supposed to get their first MMR shot between 12 months and 15 months of age, with a second sometime between the ages of 4 and 6.
