Bell has been a non-executive director of
Roche since 2001. A
BMJ campaign to make the results of unpublished studies on the anti-
influenza drug
oseltamivir (Tamiflu) available to researchers led to the journal's editor
Fiona Godlee urging Bell "as an internationally respected scientist and clinician and a leader of clinical research in the United Kingdom, to bring your influence to bear on your colleagues on Roche's board." Roche subsequently agreed to a wide policy of data transparency in clinical trials. Matthew Thompson and
Carl Heneghan wrote in a letter to the journal "...according to Roche's 2011 financial report, John Bell received 390 000 Swiss Francs (£260 450; €322 450; $420 000) last year for his role on the board of directors. What do Roche and its shareholders expect for this level of involvement and remuneration?" The House of Commons Science and Technology Committee report on the subject broadly supported the release of more clinical trial data but urged caution on public release of individual patient data. Bell serves on the
Genentech Board in San Francisco, and formerly served on the scientific advisory board of
AstraZeneca (1997–2000). He chairs the Global Health Scientific advisory board of the
Bill & Melinda Gates Foundation, he is a Trustee of the
Rhodes Trust, he sits on the award jury of the
Gairdner Foundation, he is a non-executive member of
Genomics England, and he is a member of
Cancer Research UK. He has advised governments and foundations in Singapore, France, Canada, Sweden, Finland, and Alberta on biomedical research. He is on the
Jenner Institute Board and the Gray Institute Board. He is on the advisory Board for the McGill Genomics Institute and the
Montreal Neurological Institute, and chairs the advisory board for the Oak Foundation and the Robertson Foundation. He attended the
2013 Bilderberg Conference. A 2021 feature article by freelance journalist Paul D Thacker in the
BMJ stated: "The government and Oxford University's failure to be open about Bell's financial ties make[s] it impossible for the public to know what, if any, interests the professor has when influencing key decisions about which of the many covid-19 tests the UK should purchase." ==Research==
