After so long and for so many months,  many people here still cannot understand and differentiate what is vaccine efficacy,  vaccine effectiveness,  symptomatic & asymptomatic patients.  They are still treating every vaccinated person who tested positive as a symptomatic patient.   They are expecting and demanding 95% protection if the vaccinated are using Pfizer or Moderna.    They are also expecting Pfizer to give 95% protection when Delta is more vicious and infectious than Alpha which was used to work out the 95% vaccine efficacy

The efficacy of Pfizer-BioNTech/ Comirnaty and Moderna COVID-19 vaccines were shown to be about 95% in preventing symptomatic and severe disease. That means that some vaccinated persons may still be vulnerable to infection.
