Does the COVID-19 vaccine change my DNA?
No, the COVID-19 vaccine will NOT change your DNA.
The Moderna and the Pfizer vaccines, as you heard, are mRNA, which does NOT get anywhere near your DNA in the actual cell.
Also, the vaccine is pretty fragile and will only last in your body for about 3 days, at most.
After 3 days, it gets destroyed. That's why it has to be frozen because it's really fragile and will not sustain normal temperatures long.
