Good afternoon doctor... the pediatrician of my son at the chinese general hospital and medical center wants me to be vaccinated by the polio vaccine. when i was a child, i did not receive any vaccine for polio. is it still all right? i'm 44 now?

The Philippines still has active cases of polio (20 in 2019, 1 in 2020). Individuals who have not been immunized should definitely take the (oral, live virus) vaccine so long as you have no underlying debilitating or immunocompromising conditions.

Per CDC, the only polio-endemic countries remaining in the world are Afghanistan and Pakistan. South East Asia is certified "wild poliovirus free." Not sure why your pediatrician would recommend this. I would check with your local public health agency before receiving a vaccine and if your child does get a vaccine it should be the injectable, not the oral.
