Hi, my kid is 3 months old. We first get
No difference in effectiveness as per studies
Thanks for asking on this platform
I have gone through the query and do understand your concern.
It is always suggested to give vaccines of the same brand if possible as it has been seen that effectiveness may decrease if there is any change.
If due to any reason the same brand is not available other may be used. Although it is not in each and every case possibilities cannot be ruled out.
Regarding the effectiveness of painless and other vaccines, there is no difference as per different studies. The only difference is slight variation in side effects as painless vaccine is made of an acellular component.
I would suggest you to follow the same brand and type of vaccine.
