Substantially reduced incidence of genital warts in women and men six years after HPV vaccine availability in Sweden

BACKGROUND: Between 2007 and 2011, opportunistic HPV-vaccination was available in Sweden and partially subsidized to girls aged 13-17, reaching a ∼30% overall coverage. METHODS: All Swedish women/men aged 15-44 were followed between 2006 and 2012 for condyloma. Average annual percent changes (AAPCs) in incidence were estimated. RESULTS: Substantial decreases were seen in women aged 15-24 from 2008-onwards (AACP-range: -8.5% to -18.5%); similar effects were seen for men aged 15-29 (AACP-range: -7.0% to -16.6%) from 2010-onwards. DISCUSSION: Despite low population vaccination coverage in women and no coverage in men, similar condyloma incidence reductions were observed among men and women, with delays of >1 years in men.
