This sounds pretty heartless. Significantly greater numbers of children are getting sicker because the R0 is around 7 compared to 2.5 before. The percentage of infected children getting very sick is holding steady I believe, but when you apply that small percentage to a greater number, you get a greater number of deaths. There is absolutely no guarantee that if you are a healthy child you won’t be affected by the “bad” outcomes. If the chance of infection goes up significantly because the variant is many times more contagious, than COVID becomes riskier for children because a much larger population will be affected by those small chances of complications and death. If Delta turns out to be no more severe than the other variants, then 2.5% of children infected will be hospitalized, .8% will need ICU care, and .1% will die. It should matter in our calculus of whether this is a big deal if 50% of the country’s children are likely to be infected or 2% of the country’s children are likely to be infected. With the highly contagious nature of the delta variants I have heard doctors saying that it is likely that nearly everyone who is not vaccinated will contract it at some point. There are 73 million kids in the US. Some are over 12 and vaccinated and some will be vaccinated in coming months as vaccines become available for younger children, so let’s apply the serious sickness and mortality percentages to just a quarter of the kids in the country. That’s 456,250 hospitalizations, 146,000 ICU admissions, and 18,250 dead kids. To put that in perspective, in 2019-2020, 188 children died of influenza and it was considered a bad year. Between 2012–2014, there were 228 diabetes-related deaths in children under 19. So we are not talking here about some miniscule number where we throw up our hands and say, “Well, it will be what it will be.” Especially not when we can do things that will lower the number like increase the overall vaccination rates of the population and wear masks in areas of high transmission to reduce spread.
Experts are going to recommend it for all children except a small minority with known issues with vaccines.
Your opinions seem to be informed by gut feelings more than math though, which is problematic. Unless you are going to post facts, I think it’s time you bow out of this conversation with your opinions.
