how well would plastic syringes hold up in -200deg storage???

Prefilled syringes are the safest and standard recommended delivery device for most modern vaccines—so why are covid-19 vaccines being packaged in glass vials in the middle of a global glass shortage?
Pre-filled syringes have emerged as one of the fastest-growing choices for unit dose medication as the pharmaceutical industry seeks new and more convenient drug delivery methods. Pharmaceutical companies are able to minimize drug waste.
The market has expanded and is exploring all options outside of the traditional process. In the past, glass syringes dominated the market, but there has been a movement toward plastic and disposable syringes.
Pre-filled syringes have been utilized across a wide range of therapeutic sectors, such as vaccines, blood stimulants, and therapeutic proteins.
Jen Psaki would stare at whichever reporter spoke, then say
“Well, nobody has ever asked me THAT question before!” then she would just keep going, ask for the next reporter without bothering to ‘Circle Back’ and answer the question.
That reporter would be swiftly, and quietly lead to the nearest exit by ‘Interns’(?), doors clanging and locking after them.
Good question.
Next tid bit — COVID vaccine manufacturers have no liability.
Go look at the temperatures the mRNA vaccines must be stored at and then look at the temperature tolerances for standard single use plastic syringes. Guess what they don’t play well with?
Is that what you want?
s/
plastic is permeable?
and, we have a world sand shortage?
Pretty much this. Standard one-use disposable syringes start to become brittle around 10 degrees C or 50 degrees F. When you get down to the -20C that the Moderna vaccine must be stored at, let alone the -70C that the Pfizer one requires for storage, the disposables (made of polypropylene) literally shatter into shards when touched.
Syringe plastic doesn’t like -20C/-4F or -70C/-94F very much and just shatters when touched or worse turns to dust when disturbed at those temperatures.
Also, yes, some plastics are permeable. :P
Kinda like frozen cpvc pipes, during a Texas ice storm?
The vaccine vials have to be stored at a very low temperature.
Operation Warp Speed awarded contracts for syringes, needles, and vials. It also awarded a contract to ApiJect Systems America pre-filling for syringe bodies from bulk vaccine. IDK why that is not being used.
Yup. CPVC will start shattering if full of water starting when temps hit 20F sustained and keep going down.
Because until last week when the Johnson and Johnson vaccine was approved, there was no vaccine that could use them - see my prior posts above. The Moderna and Pfizer vaccines require storage at extremely cold, near cryogenic temperatures where the standard syringe bodies simply cant be used.
Only in socialist countries.
the same chinese kids injection bold syringes on the other side of the sweat shop.
Thanks, make sense. I just did some checking and the Apijet injector isn't FDA approved for use with any COVID vaccine yet. By looking at the OWS contracts, it's clear the program bet heavily on Astra Zeneca (300 million doses up front), which could also make use of the Apijet.
The COVID vaccines have to be stored and transported at ultra low temperatures of up to -60 degrees C, or -76 degrees F. This is much, much lower than, say, the common flu vaccine needs to be stored at.
Because of the necessity of keeping the vaccine at such ultra low temperatures, and the specialized freezers required to maintain such temperatures, it is best to keep the total volume of material that needs to be stored as compact as possible. Thus, shipping vaccines in vials is much more compact than shipping pre-filled syringes.
speed, perhaps. Trump drove the vaccine project. that’s why it took one third of the 18 months that Almighty Holy Science insisted was the absolute minimum amount of time it would take to formulate a vaccine.
