HPV Vaccination: Myths and Facts You Should Know

Human papillomavirus (HPV) is one of the most common viral infections worldwide. While most HPV infections clear naturally without causing health problems, persistent infection with certain high-risk HPV types can lead to cancers, particularly cervical cancer, as well as some anal, penile, vulvar, vaginal and oropharyngeal cancers. Other HPV types can cause genital warts.

The good news is that many HPV-related diseases are preventable through vaccination and appropriate screening. However, misconceptions about the vaccine, especially around its safety, age, side effects and whether it encourages sexual activity, can make parents and adults hesitant.

Here are some common HPV vaccine myths and facts that every family should know.

Myth 1: HPV vaccination is only for girls and women

Fact: HPV vaccination can protect both males and females.

HPV can infect people of any sex and can cause several cancers and genital warts. Vaccination can therefore benefit both boys and girls.

The HPV vaccine for women is particularly important because persistent infection with high-risk HPV types causes almost all cases of cervical cancer. However, protecting boys and men is also relevant because HPV can cause cancers and genital warts in males and because vaccination can help reduce HPV transmission.

In India, the IAP-ACVIP recommendations include HPV vaccination for both boys and girls in the recommended age groups.

Myth 2: The HPV vaccine is given too early to children

Fact: Vaccination is recommended before exposure to HPV because it provides the greatest preventive benefit when given early.

Parents often have questions about HPV vaccine age recommendations. WHO recommends HPV vaccination as a priority for girls aged 9–14 years, before exposure to HPV.

In India, the IAP-ACVIP schedule for the quadrivalent HPV vaccine Cervavac recommends two doses for boys and girls aged 9–14 years, given at 0 and 6 months. For those aged 15–26 years, a three-dose schedule is recommended.

There is also an important India-specific development parents should know about. In February 2026, the Government of India launched a nationwide HPV vaccination programme targeting 14-year-old girls, with a single dose of Gardasil-4 provided free of cost at designated government health facilities.

These government-programme recommendations should not be confused with schedules for HPV vaccination obtained through private healthcare services. The appropriate vaccine and schedule depend on age, vaccine product and individual circumstances.

Myth 3: The HPV vaccine encourages early sexual activity

Fact: There is no evidence that HPV vaccination promotes sexual activity.

The purpose of HPV vaccination is to provide protection against HPV before exposure to the virus. Giving the vaccine during adolescence is a preventive health measure and does not indicate or encourage sexual activity.

Vaccinating before exposure simply gives the immune system an opportunity to develop protection when the vaccine is most effective.

Myth 4: The HPV vaccine is unsafe

Fact: Extensive evidence supports HPV vaccine safety.

HPV vaccine safety has been evaluated through clinical trials and years of safety monitoring involving millions of vaccine doses. WHO's Global Advisory Committee on Vaccine Safety has found the overall safety profile of HPV vaccines to be reassuring. More recent WHO safety reviews have also found no new safety concerns that would alter recommendations for HPV vaccination.

As with any vaccine, some people may experience temporary side effects. These are generally mild and resolve on their own.

What are the HPV vaccine side effects?

Common HPV vaccine side effects can include:

• Pain, redness or swelling at the injection site
• Headache
• Fever
• Dizziness
• Nausea
• Muscle or joint pain
• Tiredness

For example, Indian clinical trial data for Cervavac found injection-site pain and headache among the most common reactions, with most adverse events being mild to moderate and resolving within a few days.

Some adolescents may faint after vaccination. This can occur with injections in general and is particularly relevant in adolescents. Sitting or lying down during vaccination and remaining under observation for at least 15 minutes afterwards can help prevent injury from fainting. Serious allergic reactions are extremely rare.

Myth 5: The HPV vaccine eliminates the need for cervical cancer screening

Fact: Vaccination and screening are complementary, not interchangeable.

HPV vaccines protect against the HPV types included in the vaccine, but they do not protect against every HPV type that can cause cancer. Therefore, vaccination does not eliminate the need for recommended cervical cancer screening.

This is particularly important in India, where strengthening both HPV vaccination and cervical cancer screening is an important part of cancer prevention. WHO recommends that HPV vaccination and cervical screening be implemented together as complementary prevention strategies.

Women should follow screening recommendations appropriate to their age and individual risk, as advised by their healthcare provider.

##Myth 6: HPV infection is rare

Fact: HPV infection is very common.

HPV is transmitted through intimate skin-to-skin contact and many infections cause no noticeable symptoms. In most people, the immune system clears the infection naturally.

The concern is persistent infection with certain high-risk HPV types. Over time, these infections can cause cellular changes that may progress to cancer if not detected and treated.

This makes preventing HPV infection before exposure an important part of long-term cancer prevention.

Myth 7: If someone is older, there is no point in getting the HPV vaccine

Fact: The greatest benefit comes from vaccination before HPV exposure, but vaccination may still be considered at older ages.

HPV vaccination is most effective before exposure to the virus. However, previous exposure to one HPV type does not necessarily mean a person has been exposed to every HPV type covered by a vaccine.

For people who were not vaccinated at the recommended age, the decision to vaccinate later depends on factors such as age, previous vaccination, potential future exposure and local recommendations. IAP-ACVIP recommendations in India include vaccination through age 26, with a three-dose schedule for those starting vaccination at 15–26 years. Adults considering vaccination should discuss the potential benefits with a qualified healthcare professional.

Myth 8: The HPV vaccine treats an existing HPV infection

Fact: HPV vaccines prevent new HPV infections; they do not treat an existing HPV infection.

This is an important distinction. HPV vaccination is preventive, not a treatment for an existing HPV infection, genital wart or HPV-related cancer.

That is why vaccination before exposure is so important. It allows the immune system to develop protection against the HPV types targeted by the vaccine before an infection occurs.

What Are the Benefits of HPV Vaccination?

The HPV vaccine benefits extend beyond preventing HPV infection. Vaccination can help prevent infections caused by vaccine-targeted HPV types and reduce the risk of HPV-related pre-cancers, cancers and genital warts, depending on the vaccine used.

HPV vaccination is particularly important for preventing cervical cancer. WHO identifies vaccination of girls aged 9–14 years, together with cervical screening and appropriate treatment of precancerous lesions, as key components of cervical cancer prevention.

HPV Vaccination: The Bottom Line

The HPV vaccine is an important cancer-prevention tool, not simply a vaccine against an infection.

The key facts to remember are:

• HPV infection is common and can affect people of any sex.
• HPV vaccination works best when given before exposure to the virus.
• HPV vaccine safety is supported by extensive clinical and real-world safety data.
• Most HPV vaccine side effects are mild and temporary.
• HPV vaccination does not encourage sexual activity.
• Vaccination does not replace recommended cervical cancer screening.
• The recommended vaccine, age and number of doses depend on the vaccine product, age and individual circumstances.

For parents, the most important step is to speak with a qualified gynaecologist, paediatrician or a healthcare professional about the appropriate HPV vaccine age, vaccine product and schedule for their child.

Prevention starts before disease develops. HPV vaccination, combined with appropriate cervical cancer screening, can help protect individuals and future generations from HPV-related disease.
