This is not science. This is us giving them an inch and them taking a mile. The shots we have taken to protect the vulnerable do NOT prevent infection, transmission or immunity, regardless of how many people take them. There are no long term safety studies for children and fertility. This has gone far enough. It is unethical to experiment on the young to shield the old.
