which vaccination is better painful or painless

Both are equally effective from the vaccination perspective and give equal protection. However the painless option does not cause or can cause less post vaccination reactions like fever pain discomfort body ache etc. It is a personal choice as the painless ones are a bit more expensive.

hey,
DPwT painful vaccine, has reactogenicity like pain, swelling, fever. and painless DPaT vaccine has much lesser reactogenicity.

however , regular DPwT painful vaccine provides more protection as compared to the painless DPaT vaccine. Therefore, Indian Academy of Pediatrics has recommended regular DPwT vaccine over the painless DPaT vaccine.
