By design -- as far es the ON is concerned -- a vaccine has the potential to make a strong immune system more resilient, but in contrast a weak immune system might suffer more likely from adverse reactions. Doesn't that sound like the common "the strong will survive"-refrain of social darwinism aka eugenics? The line has to be drawn somewhere and this line may be manipulated by choosing the right subjects for tests. A vaccine might be of little harm to a well fed middle class steak eater but not so for the rest of humanity. Urban (talk) 08:51, 25 May 2020 (UTC)
Some information I found on Stem cell therapy used in vaccines
Not sure if these links are useful to anyone, I did a search of stem cell therapy being used in vaccines. I will be looking further into it. Sorry if this information is not useful.
