Approved vaccines are effective, they stop infections at least in 95% of cases on average for 10 years. Covid vaccine was tested in clinical trials which showed strong efficiency preventing infections.
That means that covid vaccines should be mandated to everyone, young and old and they will help to almost eliminate covid via heard immunity, right?
What went wrong with this reasoning? Despite vaccination most people got infected with covid anyway. The protection was short lasting (3-4 months at most). It reduced severity and hospitalizations in elderly though. Other people especially children were not that much affected anyway.
Biology is more complicated than we could infer from a simple graph.
I have no strong opinion about global warming but I am against trivialization of this science. Too many unknowns for me. How believable are the models? How warmer temperatures will affect us? I can see both negative and positive aspects. How much would it cost to prevent that versus to adapt to the change?
