Hello Erta Novitasari, thank you for asking HealthReplies.com.
Diphtheria immunization is indeed part of the immunization required by the government to prevent the occurrence of diphtheria which is very susceptible to occur in children. Indeed, for the schedule, basic diphtheria immunization is given at the age of 2 months, 3 months and 4 months, and after that is the age of 18 months and 5 years. In addition, booster immunization can be done every 10 years to form the immune system against diphtheria for a lifetime.
It's just that recently there has been a diphtheria outbreak, because there are some parents who are still not aware of the importance of diphtheria immunization for children. So as a response to the diphtheria plague, the government is promoting a movement called ORI (outbreak response immunization). This ORI is a way of giving repeat diphtheria immunization for people aged 1 to 19 years, regardless of their previous immunization status. This ORI-driven diphtheria immunization is given at a distance of 0-1-6 months (the first immunization with the second is 1 month apart, the second immunization with the third is 6 months apart).
Given that your child's age is included in the target of repeated diphtheria immunization, the health worker advises your child to be immunized against diphtheria at that time. It is better if your child is still re-immunized to provide optimal immunity from the diphtheria germ that is currently endemic.
A little from me may be useful. Thank you
