ORIGINAL: samboct Ishtarr et al I had to do a little digging on topic a couple of months ago... A few points- There are some differences in the two vaccines currently available, although more are in development. Cervarix a bivalent vaccine (protects against 2 strains), uses a more sophisticated adjuvant (an adjuvant is a compound that helps alert the immune system that it should be engaged) that is less likely to cause irritation and will allow the vaccine to stay active longer. Gardasil is a tetravalent vaccine and protects against 4 strains (including 16 and 18 IIRC which are the two strains that Cervarix protects against) but the vaccine may not last as long. Caution-the vaccine does NOT work for life- it's probable that boosters may be needed after some years. The advantage of Gardasil is that the additional strains it targets lead to genital warts in men- hence the push to immunize young men and women with this vaccine. There is a geographical linkage to the various stains of HPV-IIRC, in Thailand, the strains that are most commonly linked to cervical cancer are NOT 16 and 18. (maybe 54?) Some docs are saying that since there are a lot of strains of HPV- and you only get infected with one strain at a time- the vaccine will protect you from infection with additional strains. and that the idea that vaccination should be limited to people with no sexual history is in error. YMMV. Sam I'm not sure in which context you are using the bolded part, but I'll take a shot. ;) I don't think it's the idea of not having any sexual history exactly, it's the idea that if you vaccinate before any sexual involvement, you will prevent those particular infections when that person is sexually active. If it's given after sexual activity is already partaken by the recipient of the vaccine, it might end up being a situation of putting the cart before the horse. There is the potential for that person already being infected by the vaccine they are taking to prevent being infected. I don't think anyone in the medical community is saying "you can't have this because you're sexually active now". Did I misunderstand you here? Also, a person can get infected with as many strains of HPV and or STD's as their partner is carrying. They may or may not get infected with all or any, but it's certainly possible to get multiple infections at one go.
