I would like to add:
Weaknesses / Counters:
1) Surrogate endpoint only — HPV PCR positivity is not a clinical outcome; no CIN2/3, no cancer, no mortality measured
2) Correlation ≠ causation — HPV-cancer link is epidemiological association; Koch's postulates not fulfilled in traditional sense; detecting DNA doesn't prove pathogenic activity
3) PCR detection ≠ disease — Transient HPV infections are common and clear spontaneously; most HPV-positive women never develop lesions or cancer
4) Type replacement signal ignored — 66% higher incidence of non-vaccine HR types in vaccinated group is dismissed rather than investigated as potential clinical concern
5) No long-term clinical follow-up — Cervical cancer takes 15-30 years to develop; this 7-year study cannot assess actual cancer prevention
6) Confounding in vaxxed vs unvaxxed comparison — Unvaccinated group is small (n=859), likely differs in health behaviors, screening adherence, socioeconomic factors
7) Circular reasoning — Vaccine "works" because it reduces detection of the types it targets; says nothing about whether those types were actually causing disease in this population
8) Assumes HPV16/18 reduction = cancer reduction — Untested assumption; clinical benefit must be demonstrated, not inferred from PCR
9) High baseline HR-HPV in vaccinated group unexplained — 32% prevalence of other HR types suggests substantial ongoing oncogenic exposure despite vaccination
10) Genome validity unestablished — HPV reference genomes are in-silico constructs assembled computationally; never validated by sequencing purified, isolated viral particles; PCR/sequencing performed on mixed clinical samples where true origin of amplified fragments is indeterminate
