Simon Hollosi, the Reform candidate in Bournemouth Central, Westbourne and West Cliff, reposted “anti-vax” theories on at least three separate occasions to his 2,600 X followers.
These revelations come just weeks after Reform were criticised for allowing a doctor— who claimed the King’s cancer was caused by the Covid vaccine— to run in the upcoming local elections.
In December 2024, Mr Hollosi shared a post by William Makis, who was barred from practicing medicine in Alberta, Canada, after it was determined he posed a “risk to the public”.
The post on X read: “Pfizer and Moderna COVID-19 MRNA Vaccines cause Turbo Cancer— Top 5: Lymphoma, Brain, Breast, Colon, Lung.”
Another post shared by Mr Hollosi, in February 2025, reads: “PFIZER JUST RELEASED IT’S [sic] LIST OF SIDE EFFECTS OF ITS ‘COVID-19 VACCINE’”
A spokesperson for the Medicines and Healthcare products Regulatory Agency (MHRA) said: “The currently available evidence from clinical trials and thorough post-approval safety monitoring does not support an association between COVID-19 vaccination and an increased risk of cancer.
“Peer-reviewed, population-level studies across the UK and Europe, which together included millions of people, found no evidence of increased rates of cancer.”
This is not the first occasion Reform’s stance on vaccines has been questioned.
A Guardian report in December 2025 revealed that a third of Reform UK’s council leaders across the country have expressed vaccine-sceptic views.
In September 2025, Aseem Malhotra, a British cardiologist and senior adviser to US health secretary Robert F Kennedy, claimed the Covid vaccine caused cancer at the Reform party conference.
The remarks drew immediate condemnation from the health secretary, Wes Streeting, and others.
“When we are seeing falling numbers of parents getting their children vaccinated, and a resurgence of disease we had previously eradicated, it is shockingly irresponsible for Nigel Farage to give a platform to these poisonous lies,” Streeting said.
A Reform UK spokesperson said: “Our Candidates, like many, will have a social media history.
“Before joining a political party all candidates may have posted or shared messages that are later to be found to be out of keeping with their Party’s views or policies.
“Reform UK respects and supports the sterling work undertaken by scientists and the NHS in developing and rolling out safe vaccines used to protect our population, particularly the most vulnerable over the past few years.
“We do not expect our candidates to continue sharing any views publicly that are not in keeping with our Party Political Views and policies and there is no recent evidence of that occurring in [Mr Hollosi’s] case.”
