Do Covid vaccines alter your DNA?
Many social media posts have centred on the idea that Covid vaccines can alter your DNA, but this just isn’t the case.
Many Covid vaccines, such as the Pfizer/BioNTech and Moderna vaccines, are forms of messenger RNA (mRNA) vaccine.
Although some traditional vaccines may use modified or inactive forms of a virus to help people build up immunity, mRNA vaccines do not contain any live virus.
The mRNA vaccines use codes for a specific antigen which, when produced within the body, is recognised by the immune system.
After cells have made copies of the harmless virus protein unique to the virus, the body destroys the genetic material from the vaccine.
The immune system is then equipped with antibodies prepared to fight a real case of the virus in the future. A person’s DNA is not altered by the process.
