How is Pfizer gold standard? Needs to be stores in -70 degrees. Still needs to be manually diluted before jabbing. Do you really trust the pinoy nurses to do the dilution properly?pfizer-biontech dosage is 0.3ml each jab 3 weeks apart while moderna dosage is 0.5ml each jab 4 weeks apart. yet the former efficacy is a few percentage points better than the latter. better efficacy, better efficiency. that’s why the former is the gold standard. moderna takes the silver.
