How does the HPV vaccine work?
assistant
The HPV vaccine works by helping the body build immunity against certain strains of the human papillomavirus (HPV). It does this by introducing a harmless version of the virus or its antigens, which then stimulates the body’s natural defenses to produce antibodies against the virus. The antibodies produced help protect the body from infection if it is later exposed to the HPV virus. With proper immunization, the HPV vaccine can help prevent cervical cancer and other diseases caused by HPV.
