As from my perspective (EU-based, so maybe not comparable) I’d happily give up more than 10% of my monthly salary just to stand a chance of getting a vaccination this quarter.
(I fully appreciate that it’s easy to say this when you are in a wealthy nation and have a lot more disposable income than many people in the world… but I guess what I’m saying is for such a unique and important situation as the pandemic, it’s probably not an unreasonable price to pay.)
