Both are good.but i suggest better go with whole cell vaccine even if painful.

There is nothing painless or painful.. Practically it's injection so it's going to pain a bit..depends on injecting technique and post injection management.

At 6 wks ur baby will have DTP, HiB, Hep. B, and IPV Plus Pneumoccocal vaccine Plus Rotavirus vaccine In DTP  component if u go for whole cell ie DTwP It may cause pain fever and sometime swelling at vaccination site In DTP component if u go for accelular ie DTaP It doesn't  cause pain fever and swelling at vaccination site Both Vaccine ie whole cell or accelular are equally good, And effective
