HPV Vaccine Side Effects: What’s Normal, What’s Not, and When to Get Help

The HPV vaccine helps protect people from certain kinds of cancer caused by the human papillomavirus (HPV). Doctors and health experts around the world say the vaccine is safe and works well. Millions of people have received it.

Still, many parents and teens want to know about side effects before getting the shot. Most side effects are mild and go away quickly. Serious problems are very rare.

Here’s what you should know about HPV vaccine side effects and when to call a doctor.

What Is the HPV Vaccine?

HPV stands for human papillomavirus. This virus can cause:

Cervical cancer
Throat cancer
Anal cancer
Genital warts

The HPV vaccine helps your body fight off the virus before it can cause disease. The vaccine is usually given to kids and teens around ages 9–25, but older teens and adults above 25 can get it too.

Common HPV Vaccine Side Effects

Most people who get the HPV vaccine have only mild side effects. These are normal signs that the body is building protection.

Sore Arm

The most common side effect is pain where the shot was given.

Your arm may feel:

Sore
Red
Swollen
Warm

This usually lasts a day or two.

Feeling Tired or Sick

Some people may feel a little sick after the shot. Common symptoms include:

Headache
Tiredness
Muscle aches
Mild fever
Nausea

These side effects are usually mild and go away within a few days.

Studies of millions of vaccine doses have found these are the most common reactions.

Fainting After the HPV Vaccine

Some teens faint after getting shots, including the HPV vaccine. This is called syncope.

Fainting is usually caused by stress, fear, or nervousness about needles, and not by the vaccine itself.

Signs that someone may faint include:

Dizziness
Sweating
Blurry vision
Pale skin

Doctors often ask patients to sit for 15 minutes after getting vaccinated to help prevent falls and injuries.

Rare but Serious Side Effects

Serious side effects are very rare. Health experts around the world carefully watch vaccine safety.

Severe Allergic Reaction

A very small number of people may have a serious allergic reaction called anaphylaxis.

Signs include:

Trouble breathing
Swelling of the face or throat
Hives or rash
Fast heartbeat
Feeling very weak

This usually happens soon after the shot. Medical workers are trained to treat it quickly.

Guillain-Barré Syndrome (GBS)

Some people worry about a rare nerve problem called Guillain-Barré syndrome, or GBS.

GBS can cause:

Weakness
Tingling
Trouble walking

Large safety studies found no clear link between the HPV vaccine and GBS. Researchers studied millions of vaccine doses and found the risk to be extremely low.

Does the HPV Vaccine Cause Autoimmune Diseases?

Many studies have looked for a connection between HPV vaccines and autoimmune diseases. Researchers have not found evidence that the vaccine causes these illnesses.

Large reviews involving millions of people found no increased risk of autoimmune disease after HPV vaccination.

When Should You Call a Doctor?

Most side effects are mild and go away on their own. But you should get medical help right away if someone has:

Trouble breathing
Chest pain
Severe swelling
A very high fever
Trouble walking
Severe weakness
Symptoms that keep getting worse

These reactions are rare, but it’s always best to be careful.

How Long Do Side Effects Last?

Most HPV vaccine side effects do not last long.

Side Effect	How Long It Usually Lasts
Sore arm	1–3 days
Headache	1–2 days
Mild fever	1–2 days
Tiredness	1–2 days
Dizziness	A few minutes to hours
