It’s unfortunate that the shot series can run you $50k in the US if you don’t have insurance or your insurance is run by assholes.
One person needed the shot and was told they had 10 days initially so were not super worried. They were then told by the heath department they actually only had three days to do it. The health department referred them to a hospital. The hospital said since it happened where it did, they would need to go to a different hospital. That hospital did not have the shot. The initial hospital was reluctant to provide it because it was expensive but eventually caved and gave it to them.
I agree: get the shot. But don’t expect it to necessarily be easy.
