Brother, I’m not sure if these are rhetorical questions or not. But if I can just answer a few:
Originally it was thought that COVID-19 was not much of a risk to most healthy children. Now with the variants, that has changed. This virus is mutating. This is why it’s so important to “get ahead of it”, so to speak (even though we really haven’t been able to due to other factors, sadly).
As I mentioned before, the vaccine’s biggest protection is against severe hospitalization and death. Even the Governing Body has stated that the vaccine does provide a higher measure of protection! I know you may not trust the secular authorities, but we all trust the GB has prayed and PRAYED for guidance on how to handle this, and it seems that they trust the medical experts.
The vaccine was developed so quickly because a) they had all the resources and none of the red tape they usually work with and b) the technology was already there. There’s no conspiracy here! That’s just the power of unlimited funds and thousands of people working to get it done.
Also, immunity does not always last a lifetime, and other vaccines require boosters. I had to have a second chicken pox vaccine as an adult, and tetanus is supposed to be redone every 10 years. Jehovah has created our bodies to be amazing at many things, but sadly our immune systems aren’t perfect, so they do need a “boost” at times.
I’m not trying to tell anyone to get the vaccine by the way, just trying to clear up some things! And maybe our resident virus expert can correct anything I may have gotten wrong 😄
