What Is the HPV Vaccine? Who Should Receive It, Its Protection and Side Effects

The HPV vaccine protects against the Human Papillomavirus (HPV), a virus that can cause a number of diseases, most notably cervical cancer. HPV is one of the most common sexually transmitted viruses, and most people may encounter it at some point in their lives.

The HPV vaccine aims to prevent infection by priming the body’s immune system against this virus in advance. By providing protection against high-risk HPV types in particular, it substantially reduces the risk of developing cervical cancer.

HPV infection often progresses without symptoms. In some cases, however, it can lead to genital warts, cellular changes and, over time, the development of cancer. Prevention is therefore of great importance.

Detailed information about cervical infections is available on our related page.

The HPV vaccine can be given to both women and men. Protection is greatest when it is administered before sexual activity begins, but it can also be given at older ages and still provide benefit.

The HPV vaccine does not treat an existing infection; its main purpose is to provide protection before infection develops. It is therefore an important part of a preventive health approach.

In this article we examine in detail what the HPV vaccine is, who should receive it, how protective it is and its possible side effects.

What Is HPV (Human Papillomavirus)?

HPV (Human Papillomavirus) is a very common group of viruses that affects the skin and mucosal tissues. With more than 200 different types, some HPV types follow a harmless course, while certain high-risk types are associated with the development of cancer.

HPV is transmitted most often through sexual contact. Transmission is possible not only through full intercourse but also through skin contact, which makes it a virus that spreads quite easily.

Most HPV infections can be cleared spontaneously by the immune system. In some cases, however, the virus persists in the body and can lead to cellular changes over time.

Conditions HPV Can Cause

• Genital warts
• Changes in cervical cells
• Cervical cancer
• More rarely, other cancers of the genital area

Because HPV infection often progresses without symptoms, it can be difficult to detect. Prevention and regular check-ups are therefore of great importance.

Since HPV-related problems generally affect cervical health, they should be evaluated together with infections of this area. Detailed information about cervical infections is available on our related page.

Being properly informed about HPV is very important for understanding prevention methods and taking precautions early.

What Is the HPV Vaccine?

The HPV vaccine has been developed to protect the body against the HPV virus. It reduces the risk of infection by preparing the immune system against the virus in advance.

The HPV vaccine contains no live virus. It therefore cannot cause disease; it simply stimulates the immune system to provide protection.

The main goals of the vaccine are to prevent HPV infection, reduce the risk of cervical cancer and prevent the formation of genital warts.

The HPV vaccine is effective particularly against high-risk HPV types.

This vaccine is a preventive measure; that is, it does not treat an existing HPV infection. It is therefore recommended that it be given as early as possible.

The HPV vaccine is regarded today as one of the most important components of preventive gynecological health care.

Why Is the HPV Vaccine Important?

The HPV vaccine is today one of the most effective preventive measures against HPV-related diseases, above all cervical cancer. Because HPV infection often progresses without symptoms, providing protection before disease develops is of great importance.

Some HPV types can lead to cellular changes over time and pave the way for cancer. Since this process unfolds over years, precautions taken early can be life-saving.

The Importance of the HPV Vaccine

• Substantially reduces the risk of cervical cancer
• Prevents HPV-related genital warts
• Provides protection before infection develops
• Reduces the spread of HPV within the community

Because HPV-related diseases generally affect cervical health, regular monitoring of this area is also important. Detailed information about cervical infections is available on our related page.

As part of preventive health care, the HPV vaccine offers considerably higher protection when administered at a young age.

Who Should Receive the HPV Vaccine?

The HPV vaccine can be given to both women and men. The vaccine offers its greatest protection when administered before exposure to the virus.

For Women

• Generally recommended between ages 9 and 26
• Ideally given before sexual activity begins
• Can also be administered at older ages

For Men

• Recommended to reduce HPV transmission and for personal protection
• Provides protection against genital warts and certain types of cancer

At What Age Should It Be Given?

HPV vaccination is generally started during adolescence. If it has not been given earlier, however, it can also be administered at older ages.

The HPV vaccine does not only provide individual protection; by reducing the circulation of the virus in the community, it also contributes to public health.

It is therefore an important preventive measure for individuals in the appropriate age groups.

How Many Doses of the HPV Vaccine Are Given?

The HPV vaccine is administered according to a dose schedule determined by age. Completing all recommended doses is important for the vaccine to provide full protection.

Ages 9–14

• A total of 2 doses are given
• The second dose is given approximately 6 months after the first

Age 15 and Over

• A total of 3 doses are given
• Administered at months 0, 2 and 6

Completing the vaccination schedule on time enables the immune system to mount a strong response against HPV.

Missing doses can reduce the protection provided by the vaccine, so adhering to the recommended schedule is important.

How Protective Is the HPV Vaccine?

The HPV vaccine provides a high level of protection, particularly against high-risk HPV types.

Key Points on Protection

• Provides strong protection against the HPV types that cause cervical cancer
• Can be effective against genital warts
• Protection is greatest when given before exposure to the virus

The protection provided by the vaccine is long-lasting and produces a durable response in the immune system.

Because HPV has many types, however, the vaccine does not protect against all of them. Regular check-ups must therefore continue.

Which Diseases Does the HPV Vaccine Protect Against?

The HPV vaccine protects against many diseases caused by HPV.

Main Conditions It Protects Against

• Cervical cancer
• Genital warts
• HPV-related cellular changes

Because HPV infection generally affects cervical health, regular monitoring of this area is important. Detailed information about cervical infections is available on our related page.

By providing protection particularly against the high-risk HPV types that cause cancer, the vaccine plays an important preventive role.

Is the HPV Vaccine Safe? What Are Its Side Effects?

The HPV vaccine has a high safety profile and is widely used around the world.

Possible Side Effects

• Pain at the injection site
• Mild redness or swelling
• Headache
• Mild fever

These side effects are generally short-lived and resolve on their own.

Serious side effects are very rare. The HPV vaccine is therefore regarded as a safe preventive health measure.

What Should Be Considered After HPV Vaccination?

No special restrictions are generally needed after HPV vaccination, but a few simple precautions are recommended:

• Tenderness may occur at the injection site
• Strenuous exercise can be avoided for the first 24 hours
• Possible side effects should be monitored

Daily life can continue as normal after vaccination.

Is a Smear Test Still Necessary for Those Who Have Been Vaccinated?

Even after HPV vaccination, smear testing (cervical screening) should continue.

The reason is that the HPV vaccine does not protect against all HPV types. The vaccine protects against the most common and highest-risk types, but other types can, though rarely, cause infection.

Regular gynecological check-ups should therefore not be neglected, and smear testing should be performed at recommended intervals.

Screening tests are of great importance for the early detection of HPV-related diseases. Detailed information about cervical infections is available on our related page.

Does the HPV Vaccine Affect Sexual Life?

The HPV vaccine has no adverse effect on sexual life.

On the contrary, by providing protection against HPV, it reduces the risk of infection and supports a safe sexual life.

The vaccine also has no adverse effect on fertility.

Can the HPV Vaccine Be Given During Pregnancy?

The HPV vaccine is not routinely recommended during pregnancy.

If vaccination is planned, it is preferable to complete it before pregnancy. If the vaccine series has begun and pregnancy occurs, the remaining doses are postponed until after delivery.

Specialist evaluation is essential in this situation.

Is Protection Still Needed After HPV Vaccination?

Yes, attention should still be paid to protective measures after HPV vaccination.

This is because the vaccine does not protect against all HPV types and is not effective against other sexually transmitted infections.

Safe sexual practices therefore remain important.

What Happens If I Do Not Get the HPV Vaccine?

Without HPV vaccination, a person has no vaccine-induced protection against HPV infection.

In that case, the risk of encountering HPV persists, genital warts may develop, cervical cellular changes may occur and the long-term risk of cancer may increase.

The HPV vaccine is therefore an important step in preventive health care.

The Relationship Between HPV Infection and Cervical Cancer

Certain high-risk HPV types can cause changes in cervical cells over time.

These changes can progress over the years and lead to the development of cervical cancer.

This process generally advances slowly and can be brought under control if detected early.

Detailed information about cervical infections is available on our related page.

The HPV vaccine is one of the most important preventive measures aimed at stopping this process before it starts.

Is the HPV Vaccine Repeated?

Once the recommended doses have been completed, the HPV vaccine is generally not repeated.

Any missing doses should be completed, however, and questions relating to newer vaccine formulations should be evaluated separately.

The decision should be made according to the individual’s situation.

The Relationship Between the HPV Vaccine and Genital Warts

Some HPV types cause genital warts. The HPV vaccine protects against a number of these types.

The vaccine can therefore reduce the risk of developing genital warts; it does not treat existing warts, however, and can only help prevent new ones from forming.

Who Should Be Vaccinated and When?

The HPV vaccine can be given to both women and men. Protection is greatest when the vaccine is administered before sexual activity begins.

Age Group	Recommended Protocol
Girls and boys aged 9–14	Two doses are recommended. The immune response is strongest in this age range.
Individuals aged 15 and over	Three doses are recommended.
Women and men aged 26–45	Individuals who have not been vaccinated or who have missing doses may benefit from vaccination following a physician’s evaluation.

Prof. Dr. Melahat Atasever explains in detail the benefits vaccination can offer — regardless of the individual’s age or prior HPV exposure — and creates a personalized vaccination schedule.

Does Vaccination Replace Screening Tests?

No. The HPV vaccine greatly reduces the risk of cancer but does not replace routine screening with the smear test and the HPV DNA test. Even if you have been vaccinated, continuing regular screening remains important because of other, rarer HPV types that can lead to cancer and because of other gynecological conditions.

At our clinic, regular gynecological check-ups and screening tests continue without interruption after vaccination.
