Most people seem to be overlooking that even 62% efficacy means that 62% will have immunity to Covid and the remaining 38% will have a milder disease.
None of the people vaccinated in the trails required hospital treatment.
Also something that really annoys me is the comparison to the flu jab. The reason the flu jab is 60% effective is that they predict which multiple strains of flu will be prevalent that year and adjust the jab accordingly. The Covid vaccine is targeting one single strain.
