Positivity rate is trending downward the last couple of days, which is good.
HVAC Photocatalytic Oxidation pilot testing is currently being finalized on the TTC’s streetcar fleet. In-service efficacy test results and peer agency data from similar pilots are still pending for this technology.
As part of the TTC’s efforts to mitigate airborne transmission, TTC staff have also commenced upgrades to the vehicle filter systems. The goal is to upgrade to MERV 13 filters, which are currently recommended by professional organizations, such as American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), for reducing airborne aerosol exposure to COVID-19. Typically, transit vehicles are designed to use HVAC filters in the range of MERV 5 to MERV 8. Table 2, shown below, details the status of filter upgrades for each mode.
Pilot testing to upgrade the Wheel-Trans bus fleet with a standalone filtration device that accommodates the vehicle’s compact HVAC design, is ongoing and is targeted for completion in Q3 2021
With respect to surface disinfection, the TTC continues to follow guidelines established by the Province of Ontario and is disinfecting vehicles twice daily while evaluating other available surface treatments.
As a pilot, the TTC has engaged a third party supplier to investigate the use of copper coating material as a means for surface treatment for COVID-19. Phase 1 testing has already been completed between this vendor and Vancouver’s Translink agency. Phase 2 testing is scheduled to commence in July with the inclusion of TTC’s subway fleet.
Takes a couple of weeks after any vaccination dose before any noticeable effects. Some still get COVID-19 within that timeframe.A bit distressing that the cases aren't declining very quickly. At this rate we're actually going to need vaccinations to get the numbers down.
I think the more important question is how effective is it at preventing serious illness (requires ICU) and death.I don't think we will see a massive drop untill people get the second shot.
Even this low quality science infotainment story actually has a line in it admitting the headline is totally false.I don't think we will see a massive drop untill people get the second shot.
Following the monograph means many of the infections found in the study occurred shortly after subjects received their first doses, and not two weeks later and beyond when immunity is thought to increase as a result of the injection.
Even this low quality science infotainment story actually has a line in it admitting the headline is totally false.
It's almost as though Canadian media are anti-vaxx. Actually, I'm leaning to not even require the "almost" in that statement at this point.
Ruh roh.I don't think we will see a massive drop untill people get the second shot.
Anyhoo, the part 2 to that Qatar study:

Early efficacy of first Pfizer COVID-19 shot in new study doesn't disprove Canada's dosing strategy: author
The author of a new study that cast doubt on the early efficacy of the Pfizer-BioNech coronavirus vaccine against variants of concern says he believes the data is not applicable to the situation in Canada where doses are being spaced out by up to four months.www.cp24.com

I got my Shopper's email about 12 hours before my appointment at St. Joseph's. And of course, the Shoppers offering was conveniently located in Woodbridge......Great.It figures. The day after I finally get my first shot through the province's website I finally get the email from Shopper's Drug Mart saying I can now book an appointment. It was only 20 days after I signed up for the waiting list! Oh well, hopefully someone else can use that spot.
