I bought a bidet attachement in February and use very little TP. I recommend it.

On the heels of Pfizer's vaccine announcement last week (developed jointly with BioNTeh), this week Moderna announced that the preliminary results for their vaccine show 94.5% efficacy, somewhat higher than Pfizer's 90%. However, both are fairly small sample sizes, each with fewer than 100 infections, so the difference may well be within the margin of error.
The positive, though, is the consistency of the results from two independent tests for two different vaccines. This is significant because both are mRNA vaccines, made with synthetic messenger RNA (which directs the body's protein production) so they really should have fairly consistent efficacy. The biggest practical difference between the two is the storage requirement: Pfizer's vaccine must be stored at -70C or colder, whereas Moderna's can handle six months at the more common -20C temperature, and one week in a refrigerator. We will need more than one company, so the two should complement each other. But, realistically, both of these, as well as any of the other candidates, are not going to be available for mass vaccinations until 4-6 months from now, so we need to manage the current situation until then.

Not looking forward to standing out in a line for 15 minutes in the middle of winter - summer was already annoying enough haha. Gimme that vaccine, Pfizer.

She does a great job of explaining RNA in general and mRNA vaccines in particular. If you are interested in some more reading, here is an interesting history of how this is possible today: https://www.statnews.com/2020/11/10/the-...cine-race/

The Moderna vaccine is stable at higher temperatures as well (the Pfizer needs -45C, this one only -20) so distribution on that, especially outside large centres where specialty freezers are less common, should be easier.

MONDAY 2020-11-16
Waterloo Region reported 53 new cases for today (14.7% of the active cases). 363 new cases for the week (+14), averaging 18.9% of active cases. 357 active cases (+143 in the last seven days). Next testing report on Tuesday, but the region's dashboard indicates an average positivity of 3.6% for the past week. Ontario reported 1,487 new cases today -- not a record but still the third-highest daily total to date -- with a seven-day average of 1,449 (+35). 992 recoveries and 10 deaths translated to an increase of 485 active cases, and a current total of 12,870. +3,356 active cases for the week, and 126 deaths. 33,351 tests resulted in a 4.46% positivity rate. The positivity rate is averaging 3.87% for the past seven days. ICU bed count is up to 125 (+7).
GTA is back up to new 1157 cases.

Ottawa seems to have plateaued, at least for now.

Why Moderna’s COVID-19 vaccine results represent more good news for Canada: https://outline.com/fBUvbK

Their doses include a tiny recipe for spike protein DNA (...)". Protein's don't have DNA. The mRNA is the recipe to make the proteins. And the Moderna vaccina requires refrigeration to only -20C (the BioNTech/Pfizer requires -70C).

-70C seems pretty extreme for most facilities. Would they just store it on dry ice or something?

This is fairly manageable for urban hospitals but becomes very challenging for smaller rural hospitals -- and especially so remote areas (such as our territories) or for developing countries. One strategy we may end up with is the use of BioNTech/Pfizer at the big urban hospitals with Moderna used in most other locations. Lots of logistics work remains to be planned, regardless of which vaccine is used!

Urban hospitals (like ours) will generally have the refrigeration equipment to maintain -70C. This is not the first medication with this particular storage requirement. Pfizer has developed a dry ice based storage box for smaller facilites which lack a -70C capable refrigeration facility, but there are pretty substantial limitations as described here: https://www.youtube.com/watch?v=byW1GExQ...roductions
