Pfizer's COVID-19 Vaccine Distribution May Be a Logistical Nightmare (cbsnews.com) 143

Posted by BeauHD from the what-to-expect dept.
hey! writes: Pfizer's BNT162b2 vaccine must be stored at a constant -100F/-70C temperature, presenting a logistical nightmare for hospitals, which don't normally have freezers that go that low. This is because it is an mRNA vaccine, and mRNA is unstable unless stored at extremely low temperatures. Pfizer will distribute doses in dry-ice packed "suitcase" shipping containers containing 1,000-5000 doses, but these cases only work for ten days, during which they may be opened only twice a day, each time for less than three minutes. This will pose a special challenge for rural hospitals, who can't afford specialized freezers; they'll be forced to distribute hundreds of doses a day from the dry ice packed shipping crates to avoid their stocks going bad. Rural vaccination is further complicated by the fact that the vaccine must be given in two doses spaced three weeks apart.

The Moderna MRNA-1273 vaccine candidate is also an mRNA vaccine, but can be stored at -4F/-20C. This is because Moderna has experience in stabilizing mRNA. MRNA-1273 can be stored in a regular hospital freezer, making it a better candidate for smaller hospitals and clinics, although nationwide distribution in the volumes of doses needed is still going to take an unprecedented effort. If both vaccines are approved at the same time, we'll likely see both rolled out in parallel, with smaller hospitals and clinics getting the Moderna vaccine and higher volume facilities getting the Pfizer vaccine.

      The suitcases can be refilled with dry ice, but it only extends the total design storage time from 10 to 15 days. That's probably because every time you open the case it degrades the vaccine inside, which is why you're limited to under three minutes, twice a day.

    If both vaccines are approved at the same time, we'll likely see both rolled out in parallel, with smaller hospitals and clinics getting the Moderna vaccine and higher volume facilities getting the Pfizer vaccine.

    Even if they don't, I assume that the Pfizer one is initially limited to "priority" candidates: Medical personnel, "essential" personnel who will routinely come into contact with those likely to be infected (e.g. non-medical, but essential, nursing home staff such as janitors), and rich fucks with connections. Not a whole lot of rich fucks in more remote areas, so the hospitals/clinics will probably get stock for just their staff. With that assumption, while storage is still a concern the short time frame and requirements of the "suitcases" might be manageable. (Hospitals/clinics will probably administer it rather quickly, in many cases it wouldn't sit at the destination for more than a day or three.)

    Aside from that, I found this interesting:

    Pfizer has received $1.95 billion from the Operation Warp Speed to manufacture and distribute the first 100 million doses. The government will remain responsible for distributing syringes and other medical supplies needed for the vaccination effort.

    Considering how much the federal government has fucked up the response thus far, any hospital that assumes they'll get the distribution supplies at the same time as, or before, the doses is insane. (Particularly if they're in a "blue" state or have a Democratic government and distribution begins before Jan 20.) Hopefully most are handling their logistics assuming they'll have to personally order the supplies and/or use what they have in hand, and any government assistance will help them stock back up after the fact.

      I think the reality is that most of us will get a ChadOx based vaccine because they are substantially cheaper and can be stored in a fridge. It doesn't sound like a very pleasant vaccine to take but it should do the job.

      We don't have the efficacy data for these yet, but remember that these types of vaccines have been in development the longest, and I believe, has been in trial for the most time. The very good mRNA vaccine results demonstrate it has a high chance of working but we will soon see.

      If one of the ChadOx ones (or even the J&J weakened virus version) come through then I suspect most of the world will be getting that. I also suspect part of the reason the mRNA candidates released preliminary results is because (a) the results were very good and (b) they realise they are going to be pushed aside in the news once the $5 a shot ChadOx results come in.

    The first doses will go to health care workers. The initial supply will be limited in volume. Because the Pfizer and Moderna vaccines will be ready about the same time, hospitals that can store at a lower temperatures can get the Pfizer vaccine and smaller hospitals and nursing homes can get the Moderna vaccine. Most of the vaccine for health care and nursing homes will be used immediately, so longer term storage is moot anyway.

Regular RNA is notoriously unstable, but even it can stay at -20 for weeks. Moderna is a bit secretive but what I understood from what I've seen about how they are stabilizing the RNA, it is more aimed at preventing it from being degraded by endonucleases (which are everywhere) or in the cell from stuff like ribosome collision etc. Biontech too incorporates many of these tricks. I would like to see independent comparisons of storing the biontech vaccine vs. the moderna vaccine.

    TL;DR .. the biontech vaccine too can probably last for at least a few months at -20C which may be good enough for a pandemic.

    Most decent quality fridges can become a -20C .. you just bypass the thermostat and it will likely get that low.
