Last point...always important to consider public health measures & how these may impact virus transmission, but also negatively impact marginalized groups/businesses. How do we best support the mental health & financial well-being of those impacted?
pp(p?)s: These measures may still not be enough given high rates of community transmission in Peel and Toronto, but they are certainly steps in the right direction. @IrfanDhalla

"Of 11 participants who developed severe Covid while on the trial, all were in the placebo group."
"The results also suggest the vaccine is effective in older people and those from diverse ethnic backgrounds."
Nice.
From a logistical standpoint - MUCH easier to transport.
"the vaccine can be kept in a conventional freezer at -20C for up to 6 months and that once thawed the vaccine can be kept for up to 30 days at standard refrigerator temperatures of 2 to 8C."
"A vaccine against #COVID19 is in sight, with the announcement of the first interim results in large-scale trials showing the Pfizer/BioNTech candidate is 90% effective"
Pro: Amazing- if this holds true.
Con: Science by press release, let's see the data.
pps: While clearly very promising and exciting, best to see the final data on safety and efficacy.
ppps: "People from black and minority ethnic backgrounds appear to have been as well protected as everyone else, the company says."
Additional helpful details:
-Trial is enrolling 43000 people
-They've had 94 cases of #COVID19
-Much more covid in non-vaccinated group...less than 10% of those vaccinated diagnosed with covid
-Protection seen 7 days after 2nd dose of vaccine
-Goal is to enroll up to 164 cases
"Our findings suggest that environmental contamination leading to SARS-CoV-2 transmission is unlikely to occur in real-life conditions, provided that standard cleaning procedures and precautions are enforced."
2nd example: On a 10 hour flight, 1 person (also reported in business class) likely transmitted to 16 others, out of 217 passenger & crew. Proximity a risk.
Once again: "Face masks were neither recommended nor widely used on airplanes in early March"
Could there be something about business class that facilitates transmission (e.g. seating arrangement/air flow, lax mask use)? Is this a real issue vs reporting bias? Not sure.
Other examples of rather limited #COVID19 transmission on planes here 👇
TIME on train:
-Attack rate with 1-hour co-travel time is 0.25%, and with 7 hours 0.38%
PROXIMITY to case:
-Closer to index case = higher risk (shocker).
-3.5% attack rate if sitting next to case
-Attack rate drops significantly if >2 rows apart
This is the gold standard of how to effectively conduct contact tracing, especially in stigmatized populations (see below) bit.ly/2ZQpnJC
"...prejudice against homosexuality, gay men in South Korea...discrimination & stigmatization...often unwilling to reveal their sexual identity. Thus, the Seoul Metropolitan Government consulted sexual-minority groups to discuss ways to encourage testing among gay men."👍👍👍👍
"To conduct contact tracing for this outbreak, we used multiple forms of advanced information technology, including location data from mobile devices, credit card payment history,...
