It was found all the females had antibodies against virulent strains of HPV called as 16 and 18 and it persisted in the body for about four years.

The antibodies’ levels appeared stable too over the time though it was found to be lower in the single dose females. It suggested of lasting responses.

The researchers used Cervarixx vaccine in the study. It is made by British drugmaker GlaxoSmithKline.
