"Safe" appears one time in this article and is here, in a block about why mRNA vaccines have to be kept supercold:
> Modification of the mRNA building blocks and development of the particles that can cocoon it relatively safely have helped the mRNA vaccine candidates. But this new class of vaccine still requires unprecedented freezer conditions for distribution and administration.
I would say this article doesn't address safety really at all.
The Moderna Vaccine can be kept at refrigerator temperatures. The author addresses safety in that he explains why the vaccine was able to be produced more quickly while still going through the same level of safety testing.
If you are alluding to the rumor of it modifying human DNA by quoting "modification of mRNA building blocks"-- this is a modification of a piece of the viral mRNA. It DOES NOT modify human DNA or RNA.
To add to the what the article is saying RE:safety, the vaccine only stays in one's body for a few days to a week. Then it's gone. Also Moderna made a previous mRNA vaccine for Avian flu that was safe-- no long term side effects.https://www.nejm.org/doi/full/10.1056/nejmoa2022483?fbclid=I....
