Yeah, I agree completely. It also is difficult position for health agencies to be in, because they want to make clear guidelines to prevent confusion, but there are gray areas. For example, it's completely possible that: (a) The benefits outweigh the risks of a 4th shot for any age group or (b) The risks outweigh the benefits of a 4th shot for some or all age groups [not because the risk are high, but the benefits so low] AFAIK, there aren't any super high quality studies anywhere in the world that have robust data on the 4th shot in particular for all age groups. So one health agency might guess one way, another health agency might guess another way. Reasonable people can disagree. The CDC got a little bit ahead of the science when they were initially recommending the 3rd shot, but in the long run it was proven to be a good gamble that no doubt saved thousands of lives. But now maybe that same logic is a mistake for the 4th shot. But regardless of the CDC's recommendations, most people seem to have figured out the cost/benefit for themselves: The vast majority of people in the US have 2 shots, a little under half have the booster, and very few have the 4th shot. Most people probably have made the right choices for themselves given the various risks and benefits for them personally.
