• I doubt it's "watered down" I can only imagine it comes with instructions saying "mix 1 part vaccine with X parts saline" or whatever and they're left with at least another 1 part vaccine per vial.

  • The amount I dont know about mass vaccination would fill many books, but it does strike me as odd that we've stumbled upon this fact....surely Pfizer can divide required dose volume by volume of vial to calculate the dose per vial.

    I'm currently teaching my 8 year old her Maths curriculum, and this question would not be out of place.

  • Exactly. It's not 'watered down'. It's being mixed at the correct ratios, but there's enough in each vial for 6 rather than 5 doses.
