Shaking/Inverting the Vaccine Vial

yaknowski

Any chemists care to explain why the nurse should invert the vial and not shake it.

I got the 2 doses of the Pfizer vaccine. On the first dose, the nurse must not have inverted as it was a clear solution. Second solution was cloudy.

Would this matter in reality in terms of the completeness of the vaccine?

At a guess, shaking it may heat up the liquid marginally resulting in it potentially being non-viable.

It could also result in small amount of particulate coming off the cap of the bottle into the solution, or could cause part of the solution to separate resulting in an unequal distribution?

In terms of the two doses you saw, it may just be the difference between diluted -v- undiluted.

"I got my vax" is something to brag about? Because it's such an exclusive club....

I am simply asking a question that someone might know the answer to re the vial appearing not to have been inverted on the first dose.

Spoke to nurse in work. It makes absolutely no difference. Different nurses have different ways of giving iv injections. It’s whatever way they learned/became comfortable doing it. Doesn’t make a difference to the actual solution.

It's so they don't mess up the 5g chip and the magnetic particles.

Cool, thanks for that. Was just wondering as the leaflet seemed quite precise in terms of inverting and not shaking etc.

It depends on personal preference but it can be to prevent airbubbles in the solution but I also used to flick the syringe to get rid of these

Your more likely to inadvertently throw it / drop it if you shake it. Shaking it in a closed fist would warm it up.
