What are the side effects of the 9-valent cervical cancer vaccine?

Common side effects of the 9-valent cervical cancer vaccine include redness, swelling and pain at the injection site, fever and fatigue, headache and dizziness, muscle and joint aches, and gastrointestinal discomfort.

Redness, swelling and pain at the injection site is the most common reaction after vaccination. It usually manifests as redness and swelling of the skin at the vaccination site accompanied by pain when pressing. It usually lasts for 1-3 days and resolves on its own. Fever and fatigue usually appear within 24 hours after vaccination, and the body temperature is usually between 37.5-38.5 degrees Celsius. It can return to normal in 2-3 days after appropriate rest. The symptoms of headache and dizziness are mild and can be relieved by bed rest in most vaccinated people, while a few require drug intervention. Muscle and joint soreness is mainly concentrated in the upper arms and thighs, and the pain is obvious during activities. Maintaining local relaxation can help reduce discomfort. Gastrointestinal discomfort mainly manifests as loss of appetite and mild nausea. Usually no special treatment is required, just pay attention to a light diet.

After vaccination, attention should be paid to keeping the injection site clean and dry, and avoiding strenuous exercise that may aggravate discomfort. When fever occurs, water intake can be appropriately increased and physical cooling methods can be used. If severe allergic reactions occur, such as difficulty breathing, facial swelling, etc., seek medical attention immediately. It is recommended to observe for 30 minutes after vaccination, avoid drinking alcohol and spicy food for the next 2-3 days, and ensure adequate sleep to help reduce vaccine reactions.
