By Hati HealthVerified by Hati HealthMedically reviewed by Maria GaitanidouLast reviewed

Common side effects of Gardasil 9 include pain at the injection site, headache, fever, and nausea. Serious side effects are rare but can include allergic reactions.

Understanding Side Effects of Gardasil 9

Gardasil 9 is a vaccine designed to protect against nine types of Human Papillomavirus (HPV), which can lead to cervical cancer, genital warts, and other types of cancer. Like any vaccine, Gardasil 9 may cause some side effects.

Common Side Effects

  • Pain at the injection site: This is the most frequent side effect, usually mild and temporary.
  • Headache: Some individuals may experience mild to moderate headaches after vaccination.
  • Fever: A low-grade fever might occur as the body's immune response is activated.
  • Nausea: Some people report feeling nauseous, though this is generally mild.

Less Common and Serious Side Effects

Serious side effects are rare but can occur. These include:

  • Allergic reactions: Symptoms may include difficulty breathing, rash, or swelling. Immediate medical attention is required.
  • Dizziness or fainting: Some individuals may feel dizzy or faint shortly after receiving the vaccine, which is why it's often recommended to sit or lie down for a few minutes after the injection.

It's important to discuss any concerns with your healthcare provider, who can provide guidance based on your health history and help ensure that the benefits of vaccination outweigh any potential risks.

everything went smoothly with Ashrey Clinic in Makati. I even forgot my vaccine card on my last dose of hpv vaccine yet they still allowed me to get vaccinated and then provided me with a new vaccine card. Excellent customer experience.
