Unintended Immune Response: 25% of Moderna and Pfizer Covid Vaccine Recipients Affected

A study conducted by Cambridge scientists found that more than a quarter of individuals who received mRNA Covid vaccines, such as those developed by Moderna and Pfizer, experienced an unintended immune response due to a glitch in the way the vaccine was read by the body. This glitch led to the production of nonsensical proteins instead of the desired Covid spike protein, resulting in an immune system flare-up. While the vaccines still provided strong protection against the coronavirus, this off-target effect raises concerns for future mRNA vaccines, as it could potentially lead to the production of rogue proteins. However, the researchers have identified a solution by changing the mRNA code to minimize the use of the problematic component, improving safety without compromising efficacy. Updated vaccines using this improved mRNA code are already being developed for cancer treatments and other therapeutics.
