Sure and there are people in this thread implying that that's not a relevant factor and places like the UK and US are going to be seeing massive deaths soon.
And nobody talks about the natural immunity aspect either. Even if it just blunts the severity of the symptoms, places like florida probably have had ~30% of their population infected. I'm going to guess the "bad" people who didn't wear masks, got infected, are mostly part of the non-vaccinated percentage of the population. They could be added to any vaccine percentages from a pandemic response perspective (with downsides of being less accurate count, presumably less consistent immune response ect...).
Why amidst propaganda and conspiracies pushing experimental mRNA injections?
