HPV Vaccine: Schedule, Dosage and Who Needs It

The Human Papillomavirus (HPV) is a sexually transmitted infection that can lead to serious health issues, including various cancers.

The HPV vaccine is a powerful tool in preventing infections caused by the human papillomavirus (HPV), a common virus linked to various cancers and genital warts. Despite its effectiveness, there is still some confusion about its benefits, eligibility, and safety.

What is HPV?

Human papillomavirus (HPV) is a group of over 100 related viruses that can cause infections on the skin and mucous membranes. While some strains are harmless, others can lead to:

• Cervical, vaginal, and vulvar cancers in women
• Penile cancer in men
• Anal and throat cancers in both genders
• Genital warts

How is HPV Transmitted?

HPV is primarily spread through skin-to-skin contact, including sexual activity. It can be passed even if no symptoms are present.

What is the HPV Vaccine?

The HPV vaccine is designed to prevent infections caused by high-risk HPV strains. It works by stimulating the immune system to fight off HPV before it causes harm.

What are the different types of HPV Vaccines?

There are four main vaccines:

• Gardasil 9 (Protects against 9 HPV types)
• Gardasil (Protects against 4 HPV types)
• Cervarix (Protects against 2 HPV types)
• Cervavac ( Protects against 4HPV type) – Indigenously produced in India, it is similar to Gardasil but far less expensive.

What is the cost of HPV Vaccines?

In India, many government hospitalshave programmes which offer HPV vaccines for free. But you can also get it at a private doctor’s clinic. The cost of Gardasil 9 is about Rs 12000 while that of Gardasil 4 is about Rs 4000. The cost of Cervavac is about Rs 2000.

How Effective is the HPV Vaccine?

Clinical studies show that the vaccine is over 90% effective in preventing HPV-related diseases.

Who Needs HPV Vaccines?

HPV vaccines are recommended for both males and females, typically administered during adolescence or early adulthood. The primary target populations include:

1. Adolescents and Young Adults:

• HPV vaccination is most effective when administered before the onset of sexual activity.
• The Centers for Disease Control and Prevention (CDC) recommends routine vaccination at ages 11 or 12, although it can be given as early as age 9.
• Catch-up vaccinations are recommended for those not vaccinated during the targeted age range.

1. Men and Women up to Age 26:

• Individuals who missed the vaccination during adolescence or young adulthood can still benefit from receiving the HPV vaccine up to the age of 26.

1. Men Who Have Sex with Men (MSM) and Immunocompromised Individuals:

• MSM and those with compromised immune systems are at an increased risk of HPV-related diseases.
• Vaccination is crucial for these populations to enhance protection against HPV.

Adults aged 27 to 45 years or even older can get the vaccine, if necessary.

Can older adults get the HPV Vaccine?

The vaccine is approved for adults upto the age of 45 years. But it is generally offered to people less than 26 years. Adults older than 26 years can also take the vaccine at any age, even as old as 60 or 70 years.

Why is it not generally recommended to adults over 26 years?

The vaccine is not routinely recommended after age 26 primarily because most people have already been exposed to the virus, making the vaccine much less effective. Also, adults older than 26 have usually developed long-term antibodies to the strains they were exposed to, and they are less likely to encounter new ones.

Why and When is HPV Vaccine Given?

1. Preventing HPV Infections:

• The primary goal of the HPV vaccine is to prevent infections with high-risk HPV types that can lead to cancer.

1. Before Sexual Activity:

• Administering the vaccine before the onset of sexual activity ensures optimal protection.
• Vaccination at a young age provides immunity before exposure to the virus.

1. Timing of Vaccination:

• The recommended age for HPV vaccination is 11 or 12 years.
• Vaccination can be given as a two-dose series for individuals starting the series before their 15th birthday. Those starting at or after 15 years old should receive a three-dose series.

What is the dosage schedule of HPV Vaccines?

1. Dosage Schedule:

• The HPV vaccine is administered as a series of shots.
• The number of doses depends on the age at the initiation of the vaccination series.

1. Two-Dose Schedule (Under 15 Years):

• The first dose is followed by a second dose 6 to 12 months later.

1. Three-Dose Schedule (15 Years and Older):

• The initial dose is followed by a second dose 1 to 2 months later, and a third dose 6 months after the first dose.
• Immunocompromised people also receive the 3 dose schedule.

Table of HPV Vaccine Schedule:

Age Group Doses Required

9-14 years 2 doses (6-12 months apart)

15-26 years 3 doses (0, 1-2, and 6 months)

27-45 years On doctor’s recommendation

How Does the HPV Vaccine Work?

Targeted HPV Types:

• The vaccine targets specific high-risk HPV types, including those associated with cervical and other cancers.
• Gardasil 9, the most widely used HPV vaccine, provides protection against nine different HPV types.

Stimulating Immune Response:

• The vaccine contains virus-like particles that mimic the structure of HPV.
• When administered, these particles stimulate the immune system to produce antibodies that provide protection against future HPV infections.

Preventing Infection and Disease:

• By producing antibodies against the targeted HPV types, the vaccine helps the immune system recognize and neutralize the virus, preventing both infection and the development of associated diseases.

What are the benefits of HPV Vaccination? Why should I take it?

Cancer Prevention:

• The primary benefit of HPV vaccination is the prevention of cervical, anal, and other cancers associated with high-risk HPV types.

Reduction in HPV-Related Diseases:

• Vaccination has led to a significant decrease in HPV infections and related diseases in vaccinated populations.

Herd Immunity:

• High vaccine coverage contributes to herd immunity, reducing the overall transmission of HPV in the community.

Prevention of Genital Warts:

• HPV vaccination also provides protection against low-risk HPV types that cause genital warts.

Are there any side effects of HPV Vaccine?

Common Side Effects:

• Mild and temporary side effects may include pain and swelling at the injection site, fever, and headache.
• These symptoms typically resolve on their own.

Serious Side Effects (Rare):

• Serious side effects are extremely rare but may include severe allergic reactions (anaphylaxis).
• The benefits of vaccination in preventing HPV-related cancers far outweigh the risks of serious side effects.

Safety Monitoring:

• HPV vaccines undergo rigorous testing for safety before approval.
• Continuous monitoring ensures the ongoing safety of the vaccines.

Is the HPV Vaccine Safe?

Yes! The HPV vaccine is extensively tested and has been found to be safe and effective. Common side effects include:

• Mild fever
• Pain at the injection site
• Headache or dizziness (temporary)

Does the HPV Vaccine affect Fertility?

There is no evidence that the HPV vaccine affects fertility. In fact, by preventing HPV-related cancers, it helps safeguard reproductive health.

Can boys and men take the HPV Vaccine?

Yes, boys and men should take the HPV Vaccine. HPV doesn’t just affect women. Men can get genital warts and HPV-related cancers, making vaccination essential.

Common FAQs

Can I get the HPV vaccine if I’m already sexually active?

Yes, but it’s most effective before exposure to HPV.

Does the HPV vaccine replace Pap smears?

No, regular Pap smears are still essential for cervical cancer screening.

Can pregnant women take the HPV vaccine?

The vaccine is not recommended during pregnancy but can be taken afterward.

Do I need a booster dose?

Current research suggests no booster is needed after completing the series.

Conclusion

The HPV vaccine is a safe, effective, and essential step in preventing HPV-related diseases, including cancer. By getting vaccinated, individuals protect themselves and contribute to a healthier future for everyone.
