Painless is a wrong term. While giving the injection, there is going to be pain. Also there is some chance of fever even after the so called "painless DTaP vaccine" the chance of fever and other side effects is less but not zero. While fever is common after the so called "painful DTwP vaccine" DTwP gives longer immunity as per some studies. So if you are ready to face fever for 1-2 days, you should take it. Otherwise go for DTaP
