Yes, that is a legitimate point.Questioning the risk/benefit for children is a legitimate concern.. Questioning it for adults is also a legit concern.. The difference is that adults can be persuaded to volunteer for clinical trials and are informed about the risks.. vs. Children who wouldn't understand the risk even if you explained it to them.
Obviously, the parents are consenting for the kids right now but I would entertain as reasonable concerns about that topic. They are obviously being very cautious because the problem so far is that they give such small doses of vaccine that they provoke no immune response.
So back to the drawing board and trying a slightly higher dose.
Then as you say I expect there will be a risk-benefit in that population. There are high-risk individuals in that age group and we are better to be prepared for the future because Covid has repeatedly taught us it will do the unexpected.
Most of the talk about Covid on here is talking about what it is even though we don't even know the long-term consequences and have NO idea what the next variant will look like.
Sure. As folks like BOB B say Omicron could infect a large majority of the population and create immunity thus stopping the pandemic. BUT, the virus has repeatedly demonstrated that an intense immune response is not long lived and it will mutate. There is NO rule it needs to become less virulent. That is an urban myth. That is hopium.
