Why Do You Suppose Retailers Aren’t Dispensing mRNA Injections to Toddlers so Why Not Refuse Them to All Children?

The major retailers in the U. S. (such as Walgreens, Walmart, Costco, and Rite Aid) refusing to dispense the mRNA shots to children under three years old have not yet said why they are refusing to dispense, but obviously safety is the concern (what else could it be?), so how do they explain to parents of a child a few weeks over three years old that the shots are safe for their kid, and why wouldn’t the shots be considered dangerous to all people considering they’re called “Clot Shots?”
