This is entirely normal for drug development. AIUI they also didn't test on pregnant people. Given that the aim here is to produce herd immunity, rather than sterilising immunity in 100% of the population, this should all broadly be fine.
I'm not sure if this was talked about before, but the fact that (like basically every vaccine ever) it won't initially be available to pregnant women was certainly talked about ahead of time. This isn't a fiasco; it's normal.
Medical institutions (CDC, BMJ, Public Health England), the Government, and the broader media (newspapers, TV stations, companies like Facebook) are responsible for encouraging safe and efficacious use of medicine for the good of society, but they can't do that when the narrative is co-opted by anti-vaxxers, the right, and other shameless opportunists.
