The Basics
What is HPV?
HPV stands for Human Papillomavirus, a group of more than 200 related viruses. It is extremely common; most sexually active people will be infected at some point in their lives. While most HPV infections go away on their own, “high-risk” strains can persist and cause several types of cancer, including cervical, anal, and throat cancers. “Low-risk” strains can cause skin warts or genital warts. It is spread through direct skin-to-skin contact, most commonly during sexual activity.
Vaccination Overview
The HPV Vaccine (Gardasil 9)
| Feature | Details |
| Number of Doses | Under 25s: Usually a single dose. Over 25s/Immunocompromised: A 3-dose series. |
| 3-Dose Schedule | Doses given at 0, 2, and 6 months. |
| When to get it | Ideally before becoming sexually active (ages 11–13), but it is effective and recommended for adults up to age 45. |
| The Booster | Currently, no routine boosters are required once the primary course or single dose is completed. |
| How it is given | Administered as an injection into the upper arm. |
| Suitable Age | Licensed for use in both males and females from age 9 up to 45. |
Safety & Side Effects
What to Expect After the Injection
The HPV vaccine has a very strong safety record with over 500 million doses administered worldwide. Side effects are typically mild:
Local Reaction: Redness, swelling, or soreness at the injection site (very common).
Fainting: Some teenagers may feel faint after the injection. It is recommended to remain seated for 15 minutes after the shot.
General: A mild headache, dizziness, or a low-grade fever.
Recognising Symptoms
Understanding HPV Symptoms
Most people with HPV do not have any symptoms and never know they are infected. However, the virus can still cause changes in the body over time.
Asymptomatic: Most infections have no visible signs and are cleared by the immune system within two years.
Genital Warts: Small bumps or clusters of growths in the genital area. They can be flat, raised, or cauliflower-shaped.
Cellular Changes: High-risk HPV can cause “silent” changes to cells in the cervix, which are only detectable via a smear test (cervical screening).
Cancer Signs: Persistent sore throat, ear pain, or unexplained lumps in the neck (associated with HPV-related throat cancer).
Additional Precautions
Staying Safe Beyond the Vaccine
Screening is Key: The vaccine protects against the most dangerous strains, but not all of them. Women should continue to attend regular cervical screening (smear tests) as scheduled.
Barrier Protection: Using condoms can reduce the risk of passing on HPV, but because the virus can live on skin not covered by a condom, they do not provide 100% protection.
Vaccinate All Genders: HPV affects everyone. Vaccinating males helps prevent them from developing cancers and prevents the spread of the virus to partners.

FAQ
Is the vaccine still useful if I am already sexually active?
Yes. Even if you have been exposed to one type of HPV, the vaccine (Gardasil 9) protects against nine different strains. It is unlikely you have been exposed to all of them, so the vaccine still offers significant value.
Does the HPV vaccine cause fertility problems?
No. Extensive studies have shown no link between the HPV vaccine and fertility issues. In fact, by preventing cervical cancer and the treatments associated with it, the vaccine helps protect future reproductive health.
