My baby was given easy six vaccine at week 6 which is painful vaccine . We had to go to another Doc for week 10 vaccine. Doc gave him infanrix hexa which is painless vaccine. We have read online that painless vaccine is less effective compared to painful vaccine. Is it true? We are also concerned whether it is safe for baby to switch from painful to painless vaccine from week 6 to week 10. Please clear our doubts.
