Several points:
1. At -80 degree storage requirement, it will be difficult to distribute the Pfizer vaccine as easily as other traditional vaccines say like the flu jobs as suggested above. Even with the best cold chain distribution platforms with folks like Zuellig Pharma, it's very difficult to stretch the distribution beyond the larger population centres.
(Apparently the Pfizer vaccine cannot be taken out of its -80 temp environment more than 4 times including leaving the manufacturer facility. Any ins and outs more than that will reduce its efficacy and shelf life.
Then once it's out of its storage box at the hospital or clinic, it has like an 8 minutes exposure time before it deterioates.
2. Moderna has a lower threshold temp requirement like a -30 degree.
3. Singapore has approved both Pfizer and Moderna. The first rounds will be done next week to the healthcare workers. They have enough to innoculate every single resident of the country.
Interestingly they have also bought batches of Sinovac (China.)
4. The Pfizer/Moderna prices will be between $34-40 per vaccine including the double shots. The Chinese vaccines are prices like $10 or below. The Oxford vaccines are expected to be around $4.
Basically, the Pfizer/Moderna vaccines are 1st world solution and the rest due to its easier distribution attributes (no temp requirement) and cheap prices will be more for the 3rd world. (India's main manufacturer has promised that they will not charge more than $2 per vaccine.)
5. The distribution and inoculation process will be problematic as there have been enough unrealistic expectations of the vaccines and bad news coming out of the trials that people are hesitating. A friend of mine who was on the frontline here is now on the vaccine taskforce is hesitating. But she doesn't have a choice since she has to show 'leadership' to the troops in the hospitals! (I now have to take care of her cats and dogs in case she crooks ... as long as she signs her will over to me!!)
They will need to employ the whole Tipping Point approach and layer out the multiple segments of people that need to be inoculated like the introduction of new technology or product.
6. Its been suggested that now with the availability of the vaccines, you only require like 2/3rd of the population before allowing herd immunity to kick in. If this is the case I can't see anything close to a new normal till the end of next 2022.
What's interesting is Indonesia's approach to inoculation:

It's causing quite a stir amongst the Indons I know.
