Research Progress of Human Papillomavirus(HPV)Type Competition and Type Replacement
Human papillomavirus(HPV)is one of the most common sexually transmitted pathogens,causing various cancers,and more than 200 HPV genotypes have been identified.The HPV vaccine is expected to eventually reduce or eliminate the burden of diseases attributable to HPV vaccine type.However,current vaccines do not cover all types of HPV.A concern has been raised that it may lead to type replacement following widely implementing HPV vaccination programs.Progress has been made in researching type replacement following HPV vaccination.Here,we review the research progress on the HPV type competition and type replacement.
