HPV vaccine linked to 'dramatic' drop in cervical disease

  >When the vaccination programme began, researchers thought that the vaccine would knock out two types of HPV, which cause 80% of pre-cancerous conditions. >Instead, they have found it knocks out another three types as well, which means it eliminates nearer 90% of cervical pre-cancer in Scotland. This is the real story. Everyone knew there would be a "dramatic drop"

  > "The findings will need to be considered by cervical cancer prevention programmes worldwide", the study reports. With 140,000 girls being the population of the study, results are interesting. And as "Virtually all cervical cancers are caused by HPV." [0], "Most oropharyngeal cancers (70%) in the United States are caused by HPV." [0] and the same for anal, penile, vaginal and vulvar cancer, it seems to be a big gain for public health.

  To my knowledge, the first generation prevented infection from 2 strains. The second generation added 2 more. Eventually, Gardasil-9 came out, protecting against 9 strains. But these are all precise genetic vaccines that should not affect non-included strains; they don't generally activate the immune system at large (hence their safety). Perhaps something changed since I stopped reading papers about it?
