HPV Vaccine (Gardasil): Age, Effectiveness and Cost

The HPV vaccine is one of the few vaccines that genuinely protect against cancer — cervical cancer and a number of other tumors linked to human papillomavirus. There are many questions around it: what age to get it, will it help adults, do boys need it. Let's go in order through what the HPV vaccine protects against and who it is for.

Why the HPV Vaccine Is Needed

Human papillomavirus is very common, and some of its types are oncogenic — with long-term persistence they can trigger precancer and cancer. More on the virus itself is in HPV: cancer risk and cervical cancer. The vaccine teaches the immune system to recognize the most dangerous types in advance, preventing them from taking hold in the body.

What It Protects Against: Cancer Risk and Warts

Modern vaccines protect against the main high-risk types (above all 16 and 18) responsible for most cervical cancers, as well as the types that cause warts. This is prevention not of "infection in general" but of its specific dangerous consequences — precancer, cancer and genital warts.

What Age to Get It

The vaccine gives maximum protection if given before sexual activity begins — so the optimal age is adolescence. At this age the immune response is stronger and the chance of already being infected is lower. Nonetheless vaccination is beneficial at older ages too: it protects against the types a person has not yet caught.

Gardasil and Cervarix: The Types of Vaccine

There are vaccines covering different numbers of types (for example bi-, quadri- and nonavalent). Some protect only against oncogenic types, others also against the types that cause warts. Which vaccine is available and suitable in a given case is decided by a doctor; their principle of protection is shared.

Effectiveness and Safety

When given before infection, effectiveness in preventing precancer linked to oncogenic types is very high. Years of monitoring millions of vaccinated people confirm good tolerability: most often local reactions and short-lived malaise. The HPV vaccine is a well-studied vaccine.

Do Boys and Adults Need It

Yes. Oncogenic HPV types in men are linked to cancer of the anus and oropharynx, as well as to transmitting the virus to partners; vaccinating boys is justified. The vaccine can be useful for adults too — the question is decided individually with a doctor, taking age and history into account.

The Vaccine Does Not Replace Screening

An important point: the vaccine does not protect against all oncogenic types, so it does not replace regular cervical screening (cytology, an HPV test). The vaccine and screening complement each other: together they give the most reliable protection against cervical cancer. Screening must not be dropped after vaccination.

When to Discuss with a Doctor

With a doctor you discuss whether and when to vaccinate at a given age, the choice of vaccine, and questions for boys and adults. Since HPV is sexually transmitted, this is part of the broader topic of STIs. If you are unsure whether you need the vaccine, you can describe the situation.

Frequently asked questions

  • Optimally in adolescence, before sexual activity begins: then the immune response is stronger and the chance of already being infected is lower. But vaccination is useful later too — it protects against the oncogenic types a person has not yet caught. More on the virus is in HPV: cancer risk.

  • No. The vaccine does not protect against all oncogenic types, so regular screening (cytology and an HPV test) remains essential. The vaccine and screening complement each other: together they give the most reliable protection against cervical cancer.

  • Yes. Oncogenic HPV types in men are linked to cancer of the anus and oropharynx, as well as to transmitting the virus to partners. So vaccinating boys is justified, not only girls. Since HPV is sexually transmitted, this is part of the topic of STIs.

  • The greatest benefit comes before sexual activity begins, but it is useful later too — it protects against the types a person has not yet caught. Whether to vaccinate at a given age and situation is decided by a doctor individually.

  • These are different HPV vaccines differing in the number of types covered: some protect only against oncogenic types, others also against the types that cause warts. There are bi-, quadri- and nonavalent vaccines. Which is available and suitable is decided by a doctor.

  • The HPV vaccine is a well-studied and generally well-tolerated vaccine; years of monitoring millions of vaccinated people confirm this. Most often there are local reactions (soreness, redness) and short-lived malaise. Any safety questions are worth discussing with a doctor.
