Can the HPV vaccine affect fertility?

Last reviewed: 2026-06-08

Quick answer

There is no evidence that the HPV vaccine affects fertility in women or men. Large global studies tracking millions of recipients have found no link between the vaccine and infertility. The HPV vaccine prevents cervical cancer, and it's the treatment for cervical cancer (such as surgery or radiotherapy) that can actually harm fertility.

Claims that the HPV vaccine harms fertility circulate online but don't match the data.

Large studies find no link

The HPV vaccine has been used widely worldwide since 2006, with hundreds of millions of doses given. Long-term safety monitoring in many countries, including studies tracking pregnancy and fertility after vaccination, has found no reduction in fertility and no increased risk of infertility.

The vaccine protects the very organs involved in fertility

HPV is the main cause of cervical cancer. Once cervical cancer is diagnosed, treatment often involves cervical surgery, removal of the uterus or pelvic radiotherapy, all of which can affect future fertility. Preventing HPV infection through vaccination helps protect fertility.

During pregnancy

The HPV vaccine isn't recommended during pregnancy, as a precaution rather than because of any known harm. If pregnancy is discovered partway through the schedule, the remaining doses are delayed until after delivery. Discuss timing with a doctor if you have questions.

The Hong Kong programme

In Hong Kong, the HPV vaccine is part of the Childhood Immunisation Programme, given free to Primary 5 and 6 girls to build protection before the risk of infection begins.
