Herd immunity was a hoax. This was demonstrated when they shifted the goal posts and declared vaccination prevents 'serious illness and death'.
Sounds like the anti-carbon climate fascists shifting goal posts by changing 'global warming' to 'climate change', then just conveniently blame ALL extreme weather patterns on CO2 emissions. Because they weren't sure whether it's cooling or warming anymore, being concern trolls for 'drowning polar bears' is no longer a priority for their agenda.
