THat's another thing about the US. We don't allow adjuvant vaccines. That allows them to use less of the vaccine per person. So there is more doses.

I would think it would be safer because there is less of the virus in your system. The only thing less safe is the fact people think they are safe after these vaccines.

I think if these can protect lives, i see little problem going ahead with it.
