It is one of the doubts that arise in the parents of young children regarding immunization against chickenpox. Although it is not common for a baby to become infected before the year since at birth they acquire immunity through maternal defenses, there are cases in which contagion occurs.
It has happened to me, so I think the information can be useful if your baby has already passed the disease. If your baby has had chickenpox before 12 monthsWhen you get the first dose of the vaccine, at 12-15 months, what should we do, Vaccinate him or not?
In theory, having passed the disease immunizes against any future infection, but it is not always infallible. My little daughter was two months old when she became infected with her older sister. Her sister was vaccinated, so it was a mild chickenpox, but the poor little girl took it full. It was completely sprouted. When I was one year old, when I had to vaccinate her, I told her to the nurse and she recommended that she be vaccinated because having had her so small, the immunization may not be lasting. Last week, there was an outbreak at school and she was infected again but in a very mild way. Just symptoms like flu and four ronchitas.
Let's see what the Vaccine Advisory Committee of the Spanish Association of Pediatrics recommends in these cases.
It cannot be generalized, it depends on each case and it must be the pediatrician or the nurse who determines what to do. But according to the AEP, vaccinate reinforces the protection of babies who may have developed incomplete immunity.
Generally speaking, if the baby has been infected for more than six months and has been a case of clear chickenpox, it may not be vaccinated. However, if the disease has passed before six months with a mild form of chickenpox, it should be vaccinated.
