Child cannot Walk After Jab - Do You Care?

Humanity is split between those who are deeply concerned about the roll out to young children and those who do not care and those who believe that it is a good thing. I heard that a healthy 12 year old boy could not walk after getting the jab. That is deeply concerning for me. Do you care about that happening to someone else's child or do you need it to happen to yours fir you to be concerned. Where has our empathy and compassion gone?
