Can the DTP vaccine still be administered if it's been over six months?

DPT refers to the DPT vaccine. Under normal circumstances, the DPT vaccine can still be administered after six months of age. The detailed explanation is as follows:

The DPT vaccine is a combined vaccine that protects against pertussis (whooping cough), diphtheria, and tetanus. It is formulated with pertussis vaccine components, purified diphtheria toxoid, and tetanus toxoid in specific proportions, effectively preventing these three diseases. The pertussis component contains multiple antigens from the pertussis bacterium, which activate the human immune system to produce specific antibodies, providing protection against whooping cough. The diphtheria component consists of inactivated diphtheria bacteria; through vaccination, the body produces antibodies to prevent diphtheria. The tetanus component contains inactivated tetanus toxin, which stimulates an immune response to prevent infection. The target recipients of the DPT vaccine are children aged 3 months to 6 years. Typically, three doses are completed between 3 and 12 months of age, with each dose spaced 4 to 6 weeks apart. Since administering the first dose at 6 months of age still allows completion of all three doses before 12 months, it is acceptable to start vaccination after 6 months.

If planning to receive the DPT vaccine, it is recommended to check whether the individual has any allergies to the vaccine components to avoid potential adverse reactions.
