Vaccine news: keep it cool

 notice nothing is 100 percent: but your odds are good for not getting the covid virus is you get the vaccine. Here is one discussion on the data, and other videos with some information about the Philippine's plans in the other videos.

,,,,,ah, but as the saying goes: The devil is in the details. And a spoiled vaccine doesn't work.

This discusses the problem of cold storage so that the vaccine does not spoil: 

 
the Pfizer vaccine requires ultra cold storage, which is not available in most places in the Philippines. 

But the Moderna vaccine only requires cold storage that can be found in ordinary refrigerators.

from Newsmax:

....A key advantage of Moderna's vaccine is that it does not need ultra-cold storage like Pfizer's, making it easier to distribute. Moderna expects it to be stable at standard refrigerator temperatures of 2 to 8 degrees Celsius (36 to 48°F) for 30 days and it can be stored for up to 6 months at -20 degrees Celsius. Pfizer’s vaccine must be shipped and stored at minus 70 degrees Celsius, the sort of temperature typical of an Antarctic winter. At standard refrigerator temperatures, it can be stored for up to five days.

In Africa, we ran into this problem when the measles vaccine was first released in the 1970s. We did have a refrigerator that would stay cool for 24 hours without electricity, so we could keep it frozen, but many small clinics in the small villages did not, so we had to bring it and give the inoculations in a way that the vaccine was still cold until it was ready to be given.

And then how did we transport this for our baby clinic outreach sites that might take an hour or two to get there and another couple of hours to do the inoculations? we used a beer cooler tub with lots and lots of ice.

I posted a link to this BBC article about the difficulties in getting measles vaccine in the DRC to rural patients to stop an epidemic that has killed 7000 children so far.

one will see a similar problem with the covid vaccine: and as for the Pfizer vaccine that requires ultra cold storage: sorry, no way that it will be a practical answer for stopping the epidemic in poor countries.

Tony Blair's organization has a long report about the problem of getting the vaccine into Africa: LINK

and for you conspiracy types: Yes it discusses covid passes so you can travel.

But it also points out that these infectious disease passes have been used for years: In the past, you needed one for small pox, and you still need one if you are traveling from an area with Yellow fever.

and no: it's not a micro chip but a small yellow booklet.
