Human Papillomavirus Virus Vaccine

Synonyms :

Cervarix, Nine Valent Vaccine

Mechanism :

The HPV vaccines are based on hollow virus-like particles (VLPs) assembled from recombinant HPV coat proteins. The virus possesses circular double stranded DNA and a viral shell that is composed of 72 capsomeres. Every subunit of the virus is composed of two proteins molecules, L1 and L2. The reason why this virus has the capability to affect the skin and the mucous layers is due to its structure. The primary structures expressed in these areas are E1 and E2, these proteins are responsible for the replication of the virus. E1 is a highly conserved protein in the virus, E1 is in charge of the production of viral copies is also involved in every step of replication process. The second component of this process is E2 ensures that non-specific interaction occur while interacting with E1. As a result of these proteins working together is assures that numerous amounts of copies are made within the host cell. The vaccines are designed to elicit virus-neutralizing antibody responses that prevent initial infection with the HPV types represented in the vaccine. The vaccines have been shown to offer 100 percent protection against the development of cervical pre-cancers and genital warts caused by the HPV types in the vaccine, with few or no side effects. The protective effects of the vaccine are expected to last a minimum of 4.5 years after the initial vaccination.
