Does one have to wait a full year after receiving the HPV 9-valent vaccine before getting pregnant?
The term "nine-valent" usually refers to the nine-valent HPV vaccine. Generally, it is recommended to wait one year after completing the nine-valent HPV vaccination before attempting pregnancy. Contraception is typically advised until the vaccine has been fully metabolized, as the medication in the body may potentially affect the developing fetus if pregnancy occurs.
The nine-valent HPV vaccine can prevent over 90% of cervical cancers and more than 90% of genital warts. This vaccine is generally suitable for females aged 9 to 45 years. The nine-valent HPV vaccine consists of three doses administered at 0, 2, and 6 months. Since individuals vary in physical condition, the rate of drug absorption and metabolism may differ from person to person.
After receiving the nine-valent HPV vaccine, some individuals may experience fever during the immune response phase, which could increase susceptibility to viral infections. Pregnancy during this period may pose risks to the fetus; therefore, conception is not recommended at this time. Before planning pregnancy following vaccination, a comprehensive health examination is necessary, and pregnancy should only be considered once all test results are confirmed normal.
