I am not crazy about it. My general view of all medications is that unless there is a clear benefit, it's better not to interfere in the body's systems. We never know what types of unexpected effects that changing normal responses will have. For example, some of the findings in recent years about childhood leukemia and why it is more common in developed nations.
I'm also of the view that it's better to avoid new medicines, procedures, or devices until they have been around for a bit, unless there will be a significant benefit over the current situation.
Neither of which are crazy or reactionary views - they are very much the product of having grown up in a medical household where there was a good understanding that good intentions don't always produce the desired results.
At the moment it's not at all clear to me that vaccines and boosters are going to give the best outcomes with covid long term, and they are still fairly new vaccines.
I had my two jabs in the spirit of duty to the public good, and I was in bed for two days with all over muscle cramps and a fever for the first one, so I think I've been willing to do my part. But no, I won't just go along with whatever I'm told because the authorities are panicked and I have very little patience for them telling others they have to.
Actually, that is probably the thing that's made me most likly to refuse, is the mandates and public pressure. Damage to liberal democracy and civil liberties is at least as important as public health IMO.
