This is true. I followed up with asking a Dr...who said their is no recordings of who has had what vaccine and if they did at all when donating blood. There is also no waiting period after vaccination to donate blood. The theory is it disipates after vaccination blood leaves the body before blood transfusion.

Notice how drs push for this vaccine or are very careful with their wording 'theory". Never asked or suggest I should get the vaccine. It's like we figured out we were on the same page. I learned Moderna hasn't even made vaccines before (and still hasn't but just calling this new covid vaccine).

My thoughts

If it works like a mRNA that means changes to rna and DNA occurs being that your body replicates proteins so you will probably pass it on.
