That's a quote from the article.

Did you read between the lines?

They (the people making and pushing the shots) talk about "chasing the tail" of outbreaks all across the continent just to have them "spring up again", and needing more vaccines because low coverage is causing outbreaks. It's from the exact playbook as Covid.

And since when is polio dangerous to children? I'm not an immunologist but everything I've read abouy polio says it behaves like chicken pox and that reactions in children are rare, while adults are heavily affected by the disease. Why are kids getting sick at all?

They're assuming that none of the thousands of severe cases they're seeing have to do with their shots, because they haven't looked into it. These seven are people waking up, just like the adverse events with Covid.

They literally have "experts" saying things like "we hoped this wasn't going to happen, but knew it was possible"; so they obviously didn't do proper testing, probably because it's on impoverished African kids so who cares?
