evidence: Both the Pfizer and Moderna vaccines are mRNA vaccines, which contain tiny fragments of the genetic material known as "messenger ribonucleic acid". And if social media is anything to go by, some people are concerned these vaccines can affect their genetic code. [...] Your genetic code is made up of a different, but related, molecule to the vaccine mRNA, known as DNA, or deoxyribonucleic acid. And mRNA can’t insert itself into your DNA for two reasons. [...] But GMOs are different to the mRNA technology used to make COVID vaccines. Unlike GMOs, which are produced by inserting DNA into the genome, vaccine mRNA will not be in our genes or passed to the next generation. It’s broken down very quickly.
