Lifesite News.com gives a thorough discussion of how the US federal government, in moves adopted throughout the West, changed the definition of “vaccine,” so that the mRNA gene therapies could be classified as vaccines. Otherwise the definition, in turn of ‘biological product” would have precluded defining the mRNA gene therapies as vaccines.

There was no independent scientific reason for this, other than promoting the MRNA gene therapies.
