Can I take a bath after receiving the bivalent HPV vaccine?

It is not recommended to take a shower on the same day after receiving the bivalent HPV vaccine. It is advised to wait for two to three days before bathing, as doing so earlier may lead to infection and potentially affect the vaccine's effectiveness.

The bivalent HPV vaccine helps prevent diseases caused by human papillomavirus (HPV) types 16 and 18, such as cervical cancer and cervical intraepithelial neoplasia, and is suitable for females aged 9 to 45. After injection, a small puncture site remains. If you bathe before the puncture site has healed, bacteria and dirt in the water may enter the body through the injection site, leading to wound infection. This could cause symptoms such as redness, swelling, pain, and fever. These symptoms might be difficult to distinguish from potential vaccine side effects and could also interfere with the vaccine’s efficacy. Additionally, if the bathwater is too hot, it may cause small blood vessels to dilate, increasing the risk of bleeding at the injection site. Therefore, it is recommended to wait 2–3 days after vaccination before taking a shower.

After receiving the bivalent HPV vaccine, it is also important to monitor for any side effects. You should remain at the vaccination site for about 30 minutes for observation and only leave if no unusual reactions occur. If adverse effects do appear, seek medical attention promptly. After vaccination, avoid smoking and drinking alcohol, refrain from eating spicy or irritating foods, and avoid strenuous physical activity.
