But what does "majority of people also got their second shot" even mean now? - my last one was in late 2021 and my mom (a senior) has gotten like 5 overall.

Also I've not even seen anything in the news lately, so maybe I'm just not looking at the right places but right now I am honestly not even sure if I should be getting more shots, or other ones, based on how the situation has developed in... about 22 months.

My point being: I am simply not sure if these last 2 years haven't changed how we looked at the vaccination numbers back then, because e.g. omicron even came after people were still pushing for this "basic immunization".
