In March 2010, following the publication of the House of Commons Science and Technology Committee's report "Evidence Check 2: Homeopathy", Vis signed Early Day Motion 908: Science and Technology Committee Report on Homeopathy, which was critical of the report.
Rudi Vis has signed a number of Early Day Motions that support the use of herbal medicines. These include EDM 1103: Traditional Herbal Medicinal Products Directive (2005), EDM 1549: Herbal Clinic at The Royal London Homeopathic Hospital (2008), EDM 2080: Herbal Remedies (2008), and EDM 295: Statutory Registration of Herbalists (2009).
Rudi Vis signed the February 2009 Early Day Motion 754: MMR Vaccine and the Media supporting the use of the MMR vaccine. The motion expressed disappointment with the reporting of the vaccine by Jeni Barnett on her LBC radio show in January 2009, and expressed the hope that future reporting of the issue of MMR would be less sensationalist and more evidence-based.
In May 2008 in the abortion amendments to the Human Fertilisation and Embryology Bill (now Act), Rudi Vis voted to keep the current time limit of 24 weeks in line with the scientific and medical consensus.
Animals in Medical Research
In 2006, Rudi Vis signed Early Day Motion 1850: Animals in Medical Research which noted that "animal research is only permitted where there is no better alternative and that pain and suffering are minimised and balanced against the potential benefit to humans and animals", supported "the building of the new state of the art biomedical research laboratory at Oxford University", condemned "unlawful animal rights extremism, including any violence, harassment or intimidation of those associated with lawful animal research", and supported "the well-regulated use of animals in medical research".
Rudi Vis was one of 79 MPs who signed Early Day Motion 377 noting the achievements of Charles Darwin, and calling for Darwin's birthday to be designated a public holiday to honour "one of the fathers of modern science and one of Britain's greatest, if not the greatest, scientific minds."
Policymaking On Drugs And Alcohol
Rudi Vis signed Early Day Motion 2244 calling for Government policy on alcohol and drugs misuse and harm to be based on scientific evidence. The motion came shortly after the sacking of Government drug adviser David Nutt by Home Secretary Alan Johnson in 2009.
Libel Law Reform
In December 2009, Rudi Vis signed Early Day Motion 423 calling for a reform of the English libel law. The motion noted that human rights activists, scientists, writers and journalists are currently prevented from publishing, and the public prevented from reading, matters of strong public interest due to the chilling effect of the law.
The motion was tabled following the recent formation of Libel Reform Coalition, which has the backing of Index on Censorship, English PEN and Sense about Science. Sense about Science have been campaigning in defense of a member of its board of trustees, author and journalist Simon Singh, who has been sued for libel by the British Chiropractic Association. They issued a statement entitled "The law has no place in scientific disputes".
In January 2010, Rudi Vis signed Early Day Motion 524: Recognising Climate Change which states that "this House agrees that climate change is happening and is man-made" and calls this statement a "fact, which has the support of the overwhelming majority of the scientific community".
