Hello Doctor, My baby is 1.5 months old. As per schedule, his vaccination date has approached. We took him to a local Anganvadi, they said baby just weighs 2.9 kg and is underweight for vaccine. His birth weight was 2.2 kg. They are suggesting to delay his vaccination schedule by 1 month. That means, his 1.5 months vaccine will be given after 2.5 months, and 2.5 months vaccine after 3.5 months. Is it ok to delay vaccination?
