SINGAPORE - Claims that mRNA Covid-19 vaccines could cause neurological diseases such as Alzheimer's and Parkinson's have been making the rounds on social media and messaging apps recently.
They come after the publication of a research paper in scientific journal Scivision, which suggested that mRNA vaccines such as the ones developed by Pfizer and Moderna could potentially trigger prion disease.
But local scientists have been quick to debunk these claims.
Professor Paul Tambyah, deputy director of the National University of Singapore's Infectious Diseases Translational Research Programme, said that prion disease is a result of one's proteins adopting an unusual arrangement, causing them to aggregate.
