HPV Vaccine Information

HPV Vaccine

Nearly all men and women will get at least one type of Human Papillomavirus (HPV) at some point in their lives. The HPV vaccine Gardasil 9 is now recommended for all girls and boys when they are 11 or 12 years old.

What is the HPV vaccine?

HPV immunizations are recombinant viral protein vaccines. They contain highly purified virus-like particles, but they do not contain any viral DNA. Therefore, they can’t infect healthy cells, replicate, or cause disease.

There are two types of HPV vaccines:

  • Gardasil® Quadrivalent HPV Vaccine (Genotypes 6, 11, 16, 18) — Produced in recombinant S. Cerevisiea culture, contains Aluminum Hydroxyphosphate, Polysorbate 80, sodium borate, and L Histidine.
  • Cervarix® Bivalent HPV Vaccine (Genotypes 16, 18) — Produced in recombinant Baculovirus expression vector system, contains Aluminum Hydroxide plus deacylated monophosphoryl Lipid A used as an adjuvant (AS04).
