Written question – Possible link between COVID-19 mRNA vaccines and aggressive cancers (‘turbo cancer’) in the context of Europe’s Beating Cancer Plan – E-002078/2025

Question for written answer  E-002078/2025/rev.1
to the Commission
Rule 144
Gerald Hauser (PfE)

Although ‘turbo cancer’ is not a medically or scientifically defined term, it is currently being used by doctors to describe the distinctive signs of certain cancer trajectories. Renowned oncologists at home and abroad have recently alerted us to a significant uptick in extremely aggressive, rapidly progressing cancers, particularly in people who have received COVID-19 mRNA vaccines.[1] Among other things, they point to the presence of SV40 sequences in certain vaccines – a potentially oncogenic virus fragment.[2]

• 1.What scientific evidence does the Commission currently have of a possible link between COVID-19 mRNA vaccines and the increased incidence of particularly aggressive forms of cancer (‘turbo cancer’)?
• 2.Has the Commission – as part of Europe’s Beating Cancer Plan for instance – commissioned any independent studies on these indications or is it planning any such initiatives?
• 3.Is the potential presence of SV40 fragments in vaccines currently being investigated or monitored by the Commission, its institutions, bodies, offices or agencies?
