Biography

The WHO published the following biography of Helen A. Weiss:

Weiss, Helen A

  • London School of Hygiene and Tropical Medicine
  • Ph.D.[a 2]
  • London, United Kingdom

Professor Helen Weiss is Director of the MRC Tropical Epidemiology Group at the London School of Hygiene & Tropical Medicine. A statistical epidemiologist by training, her research focuses on the epidemiology and prevention of HIV and mental health disorders in low and middle-income countries. She has a particular interest in adolescent health research and is collaborating on projects evaluating strategies to improve HIV-related outcomes among adolescents living with HIV. She is currently leads a study to pilot an intervention to improve menstrual hygiene management in Uganda.

Professor Weiss first worked on male circumcision research in 1999, leading the systematic review that first provided clear evidence that male circumcision was associated with a lower risk of HIV infection among heterosexual men in sub-Saharan Africa. She also led subsequent systematic reviews on different aspects of male circumcision including on safety of neonatal circumcision, and the effect of male circumcision on infections among women.

Professor Weiss has co-authored more than 270 peer-reviewed publications and is a member of the UNAIDS Scientific Expert Panel and the MRC Infections and Immunity Board, as well as the initial WHO Technical Advisory Group on Safe Male Circumcision.[4]

Weiss has been a co-author of numerous papers to promote male circumcision in Africa (VMMC) in the mistaken belief that it prevents HIV infection. She obviously is biased in favor of circumcision.

Population-based studies

September 2021 saw the publication of two huge population studies on the relationship of circumcision and HIV infection:

  1. Mayan et al. (2021) carried out a massive empirical study of the male population of the province of Ontario, Canada (569,950 males), of whom 203,588 (35.7%) were circumcised between 1991 and 2017. The study concluded that circumcision status is not related to risk of HIV infection.[5]
  2. Morten Frisch & Jacob Simonsen (2021) carried out a large scale empirical population study in Denmark of 855,654 males regarding the alleged value of male circumcision in preventing HIV and other sexually transmitted infections in men. They found that circumcised men have a higher rate of STI and HIV infection overall than intact men.[6]

No association between lack of circumcision and risk of HIV infection was found by either study.
