Chris Seeks Clarity On The Risk Of Spike Proteins Produced By Vaccinations
Christopher Chope Conservative, Christchurch
To ask the Secretary of State for Health and Social Care, what the potential adverse effects are of the spike proteins produced by mRNA covid-19 vaccinations.
Maria Caulfield The Parliamentary Under-Secretary for Health and Social Care, Parliamentary Under Secretary of State (Department for Business and Trade) (Minister for Women)
A vaccinated individual may be exposed to the spike protein of circulating SARS CoV-2 virus in the population in addition to spike protein produced by the mRNA COVID-19 vaccinations. Therefore, it is not feasible to attribute potential adverse effects to spike proteins produced by the vaccine specifically.
However, studies of toxicity in animals given the vaccine have been performed and allowed such effects to be detected. This is because these studies ensured that the animal was only exposed to the spike proteins through their mRNA vaccination. The toxicity studies of animals were reviewed by the Medicines and Healthcare products Regulatory Agency (MHRA) and the MHRA’s independent expert advisory group, the Commission on Human Medicines.
The study results did not indicate the presence of effects other than those expected for a vaccine. This includes, for example, an increase in body temperature, and swelling and redness at the injection site, which arise from the vaccine working to induce an immune response. The MHRA keeps emerging evidence on the safety of the COVID-19 vaccines used in the United Kingdom immunisation programme under continual review and will take appropriate action to minimise risks to patients.
