- jopsen 6y agoCurious, does anyone know if is any safety concerns with these methods?
- netsharc 6y agoWhy? It's the same liquid. It's like getting the last drop of gas when filling up your car, but there's wastage because some liquid remains in the syringes, and the amount depends on the type of syringe: https://arc-w.nihr.ac.uk/research/projects/low-versus-high-dead-space-syringes-user-preferences-and-attitudes/ https://arc-w.nihr.ac.uk/research/projects/low-versus-high-d...
- ghostpepper 6y agoHopefully someone will correct me if my numbers are off, but this is what I remember from a conversation with a nurse: A vial contains 0.24 mL of concentrated vaccine, which is then diluted with 1.8 mL for a total of 2.04 mL. This is enough for six 0.3 mL doses, or 1.8mL - which leaves 0.24 mL remaining. ie. not quite enough for a seventh 0.3 mL dose. So.. what is the method to obtain a seventh dose? The article does not say.
