Study question

[josh120775]

Can anyone point me in the direction of the studies done to show that 2 months of age is the best time to start?

I've done some digging online and can't find anything, although I may be searching wrong.

Shouldn't there be studies as each vaccine is introduced to determine the most appropriate age?

I don't believe there are any studies done showing that it's best to vaccinate during infancy. It's just easier to get parents to do it at that time.

Agreed. I've not seen any data to endorse starting at any particular age.

I don't think there is any definitive data...which is why different countries start different vaccines at different ages.
