Hello. We went to the pediatrician at six months old...and she started talking about immunization against measles and we need to get vaccinated. Although according to the plan, it's in a year. When we did DTP at five and a half months, I asked about measles, but then they said that we will come in a year and do it. I wanted to know who did it at six months old, how the reaction was, how the baby coped, how their behavior changed? I just barely decided on these vaccinations, and now again... I am very worried because the baby is still small and such loads.
