While there is no medical evidence that supports delaying immunizations, your pediatrician can discuss your options.
As a parent, you have to be comfortable with the medical decisions you make for your little one. However, there is no medical evidence to support the idea that delaying immunizations until an infant is older is the safest thing for your child.
On the contrary, the immunization schedule is developed to maximally protect our most vulnerable population, our babies. Vaccines are given on a schedule throughout the first several years of life, and some children with special needs or medical conditions may have an altered vaccine schedule. Delaying immunization is not necessary, but your pediatrician can discuss this with you on your next visit.
