Hpv and cc

Not sure if posting in the right place but just need some advice really. When I was at school I received the hpv vaccine (cervarix) which only protects against the 2 most common strains of hpv to cause cancer. I received 3 doses, which I believe was the standard amount back then to receive. However, my second and third doses were given on the same day, 7 months apart from my first dose. I know they’re not meant to do this, I believe there’s supposed to be a few months between the second and third dose. Would this effect the effectiveness of the vaccine in my body and make hpv more likely?

hi @cait11198

it is recommended that they follow the schedule, each dose was supposed to be given at 0, 1 and 6 months but it doesnt necassarily matter when the vaccines were administered aslong as you hadnt been exposed too strains 16 & 18 before the 3rd dose was administered it wouldnt have impacted your immunity against those 2 strains in particular… you are still susceptible to the other many strains of HPV including the other 12 high risk types

i had the same vaccine 15 years ago, my second shot was at 6 months and my 3rd was near the 12 month mark

“The second main study showed that two doses of Cervarix given 5 to 13 months apart were no less effective in girls aged 9 to 14 than a standard three-dose vaccination was in older subjects: all previously unprotected subjects had developed high levels of protective antibodies against virus types 16 and 18 one month after their last dose.”

there is more info on the above quoted here: https://www.ema.europa.eu/en/medicines/human/EPAR/cervarix


Thank you for your reply! Yes I had the vaccine before I became sexually active. I heard the newest vaccine they are using now protects against other strains, would it be worth getting? It’s apparently free up until 25th birthday, Im currently 24 x

Yeah the one that is offered now is gardasil9 which includes the 9 most prevalant strains 6, 11, 16, 18, 31, 33, 45, 52 and 58 (7 high risk strains and the 2 main low risk GW strains that account for 90% of GW cases) as it still doesnt cover all 14 cervical screening would still be advised

It would definitely be worth getting, it wouldnt necassarily help with a current strain or strains we have already been exposed too but it would protect you against a covered strain that hasnt already been aquired so it would reduce the chances significantly xx
