Painful vaccines, like the whole-cell DPT (Diphtheria, Pertussis, Tetanus) vaccine, contain the entire killed bacteria and can cause more pain, swelling, and fever after injection. Painless vaccines, like the acellular DPT, contain only parts of the bacteria and are less likely to cause side effects, making them gentler and more comfortable for babies. Both are effective, but the painless one is more expensive and may need more doses over time. The choice depends on the doctor’s recommendation, baby’s health, and parents' preference.
