evidence: In a recent study, published in Nature, my colleagues and I revealed that these unintended proteins were produced in a third of the 21 people who participated in the study and were vaccinated with the Pfizer mRNA vaccine. Also, those people generated an immune response against these proteins. [...] The data is clear: there is no evidence linking unintended proteins and immune responses with harm. It’s important to note that humans regularly encounter unintended proteins and generate harmless immune responses, as seen with proteins produced from our food or by harmless gut bacteria. These immune responses, which occur in all of us constantly, are controlled by our immune system to prevent them from causing damage to our bodies.
