Comment by Dr.Fiala:
"The authors describe their significant finding as "The incidence of any subsequent
HPV related disease was 6.6 and 12.2 in vaccine and placebo recipients respectively (46.2% reduction (95% confidence interval 22.5% to 63.2%) with vaccination)" This is further detailed in table 2.
Furthermore the authors describe an unexpected finding in table 3: "Impact of quadrivalent
HPV vaccine on incidence of subsequent cervical intraepithelial neoplasia grade I or worse* associated with 10 tested non-vaccine
HPV types among women who had undergone cervical surgery". The effect is similar, a 42.5% reduction.
In summary, the authors found a similar reduction in subsequent diseases of all
HPV types (46.2%) and non-vaccine
HPV types (42.5%).
This leads to the conclusion that the reduction in subsequent disease was unrelated to the vaccination. The only other possibility would imply that the vaccine was active even on virus types not contained in the vaccine."
