Nine-valent refers to the nine-valent HPV vaccine, and you can exercise after the nine-valent HPV vaccine. Nine-valent HPV vaccine is used to prevent various diseases caused by human papillomavirus (HPV) infection. The injection site of the vaccine is on the arm. If there is no discomfort half an hour after the vaccination, you can exercise appropriately while keeping your body dry to avoid inflammatory reactions at the injection site due to heavy sweating. In general, the side effects of vaccination will gradually decrease after 3 days. Therefore, if you need to do strenuous exercise such as long-distance running or playing basketball, it is recommended to do it 3 days after the vaccination so that it will not affect the effect of the vaccine and will not cause damage to the body. Women should pay attention to rest more and observe whether there is any abnormality after the vaccination with the HPV 9 vaccine.
