Some infections (e.g. polio, HPV and bacterial meningitis) can have very serious or even fatal consequences and so it is much better to avoid infection. The best way to do this is through vaccination.
Vaccination triggers the immune system to respond to an infection without actually getting the disease. Inactivated pathogens, or parts of a pathogen — or, as with HPV vaccine, synthetic virus-like particles (VLPs) produced from protein of each HPV type using recombinant DNA technology — are introduced into the body. They act as antigens. The immune system recognises these injected antigens as foreign and develops antibodies against them. Special memory cells retain a memory of the pathogen. If at a later date the real pathogen gains access to the body, the immune system reacts quickly to prevent the infection developing. Vaccination immunises a person against the disease.
Some low risk HPV types cause genital warts. Most HPV infections are asymptomatic and clear naturally but some, caused by high risk types, can persist and cause cancer. It is estimated 80% of sexually active adults develop some HPV infection.
