Judy am I missing something? That link you provided talks about Malaria NOT Covid vaccine.
“WARNING : MALARIA VACCINE DEPLOYMENT IN AFRICA
720,000 children in three countries were targetted - (Malawi, Kenya and Ghana) with an experimental vaccine, Mosquirix”
That warning is on there, Spunky. Look just above it on the very first line. I think they just threw that warning onto the site for those interested.
