U can switch but efficiency is same of both

Both are having equal immunity

Hii This vaccine (both painless and painful) fights against 6 diseases, the only difference is in pertussis. Efficacy might decrease once you change the vaccine against pertussis only rest others immunity increases. Better to give the vaccine which you have started with till 14 weeks at least. All vaccines are not 100% immune. Coverage will be somewhere between 75-95% after completing the schedule.

Efficacy wise both are same Cost wise both are different Can switch although
