Regarding the vaccine efficacy, I wish you asked why Dr. Bhattacharya thinks it's effective, but it hasn't achieved herd immunity yet, while historically all effective vaccines achieved herd immunity when the coverage reaching &lt; 70%? An example is measles, which is whole lot more contagious (250%) and reached herd immunity at the coverage of &lt; 65% during 1963 - 1964. In the part of hesitancy, lacking answers to the legit questions, makes the mandate absurd IMO.,(reply>), @ZeroSugarMatcha well I don't have any idea how you would even attempt to reach a conclusion with charts, there are just so many confounding parameters. You have to take into account lockdowns (that usually are relaxed after vaccine coverage is high), difference between apparent and actual cases for Covid, difference in approach. I try to be aware of possible explanation, but refrain from choosing a single one.,(reply>), @Дмитро Попович YouTube keeps deleting my reply. I tried to post a link to the measles cases / vaccine coverage chart from Wikipedia (there are 2, the actual one per year). I'm saying COVIT-19 vaccine chart is in contrary of the measles vaccine chart.,(reply>), @ZeroSugarMatcha Sorry I didn't quite understand your reply, what patter is not seen? I can only say that flu is very very different from coronaviruses.,(reply>), @Дмитро Попович It's a possible explanation, though I wouldn't think it's conclusive, as the pattern it's not seen in other vaccines, including those for other corona viruses like flu.,(reply>), @Ratatouille2017You are confused with the theoretical herd immunity threshold (HIT) and actually HIT. 95% is the theoretical HIT for measles, the actual HIT is below 65%, you can find the chart on Wikipedia.
