BioNTech pfizer–biontech covid-19 vaccine vials
(a) Dead-volumes (μl) of different syringe—needle combinations measured according to standard method NF-EN ISO 7886-1. (b) Actual volume administered by different syringes at 0.3-ml graduation. (c) Number of extractable dose from Pfizer–BioNTech <t>COVID-19</t> vaccine vials according to different syringe–needle combinations. The data are quoted as the mean ± standard error of mean from at least 5 (a), 50 (b) or 3 (c) independent and blinded measurements. The differences with the theoretical value (0.3 ml) were probed using t -test. * * * * P < 0.0001; * * * P < 0.001; * P < 0.05: volume of one syringe compared with the theoretical volume withdrawn (0.3 ml)
