Introduction
After receiving the vaccine, it is generally recommended to keep the injection site clean and dry for a period of time to reduce the risk of infection. Gently washing the area is acceptable, as long as you avoid vigorous rubbing or prolonged soaking. The vaccine has already been injected into the subcutaneous tissue and primarily spreads to other parts of the body through the bloodstream, rather than relying on external contact.
The 9-valent human papillomavirus (HPV) vaccine refers to the 9-valent recombinant HPV vaccine. Generally, getting the injection site wet after vaccination does not have any significant impact, as the vaccine's effectiveness does not depend on external contact. The detailed explanation is as follows:
After receiving this vaccine, it is generally recommended to keep the injection site clean and dry for a period of time to reduce the risk of infection. Gently washing the injection site is acceptable, as long as vigorous rubbing or prolonged soaking is avoided. If the injection site comes into brief and mild contact with water after receiving the 9-valent HPV vaccine, it typically will not noticeably affect the vaccine's efficacy. The vaccine has already been injected into the subcutaneous tissue and primarily spreads throughout the body via the bloodstream, rather than relying on external exposure.
In certain special circumstances, such as prolonged immersion in water or exposure to contaminated water, there may be some risks, potentially leading to local wound infection. If any discomfort occurs after vaccination, prompt medical attention is advised.
