The HPV vaccine is for women aged 16 to 26, but it is not currently free. And children under the age of 16 do not need to get the nine-valent cervical cancer vaccine.

However, it is recommended that women receive the vaccination at the prescribed age. If you need to receive the vaccination, it is recommended that you consult a doctor in advance to clarify whether you are suitable for vaccination.
