My son worked on some of this..at Merck..J&J
To simplify .... In the very beginning .. before anything is made for market...to start of making vaccines.. they use fetal cells.
after that there are none used.. they make what they need.. synthetic... and there are NO fetal cells in the vaccine given.
I robbed a bank and killed three guards but I donated all the loot to the poor. Didn't keep a penny.
Why did they do so? What was the moral necessity; or was it merely for rapid profits? Why have alternative vaccines not received such funding?
