"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.
