DPT vaccine and polio vaccine can usually be given together. However, for safety reasons, it is better to vaccinate them separately. In the current standard of childhood vaccination, DPT vaccination can be given together with polio vaccine, and there is no contraindication for the two vaccines to be given together. However, there may be adverse reactions after vaccination, and one vaccination for both vaccines may aggravate the adverse reactions. So for safety reasons, to avoid adverse reactions caused by different vaccines affecting the judgment, or the baby’s physical condition is poor, you can be vaccinated separately, which is more conducive to the baby’s health. Both DPT and polio vaccine are mandatory vaccinations for children and should be administered at the prescribed time in order to produce effective results. It is recommended that they be administered under the guidance of a specialist.
