The experimental vaccines from both Pfizer and Moderna utilize mRNA (messenger ribonucleic acid) which instructs the bodys cells on manufacturing proteins.* It is technology that has not
ever been approved for any disease, or even entered final-stage trials until now.* There have been no independently published animal studies on any of the vaccines, and it is not yet known
what effects they will have on the elderly, the very young, or women who are pregnant or might become pregnant in the near future.* Id say those are important groups whose safety is critical.
