A 🧵 on safe schools, below. (1/n)
Let's begin with other provinces who are RIGHT in the storm of their Omicron surges. Quebec has delayed opening of 'everything' to Jan 17. Ontario has delayed opening till Jan 5 to try to distribute HEPA filters & N95s for staff (not students). (2/n)
Modelling released by @SKGov predicts DRAMATIC rise in cases, hospitalizations, & ICU admits w/ #Omicron if no additional measures to reduce contacts (i.e. gathering & capacity limits).
Briefing today: NO measures to be implemented at present. Wait and see.
Here is ICU / non-ICU modelling data. Not great, as you can see. Also not being taken into account - scores of HCWs taken out of circulation as a result of widespread community transmission.
Who will look after all the patients? Many HCWs have already moved on.
"Hi Alex. With #Omicron in Canada, what's the optimal 2nd dose interval for kids b/w 5-11 who have 1 dose?"
VERY different space w/ Omicron now vs 4 weeks ago when NACI guidance was released.
We'll try for 3-4 wk interval in #SK for our 5 year-old, NOT 8. Here's why. (1/n)
Let's start by acknowledging that we have no real clinical data in this space right now. We don't know HOW protected kids b/w 5-11 are with 1 dose vs different variants like Delta or Omicron.
Kids immune systems are ++ robust, so 1 dose definitely confers some protection. (2/n)

"Hi Alex, how do I keep my holiday gatherings safe? Do I have to cancel everything?"
Depends on your risk tolerance. If your bubble has persons who are medically vulnerable, elderly, maybe reconsider.
Otherwise, use ALL measures to keep things safe as able.
Brief 🧵. (1/n)
We all know that seeing & reconnecting with friends & loved ones over the holidays is SO critically important. But with the transmissibility of #Omicron, the risk-benefit calculus has changed dramatically again. What do we do now? (2/n)

"Hi Alex. My (5 to 11) year old just got their 1st #COVID19 vaccine dose. Yay! Should we wait 8 weeks for the 2nd dose as recommended, or should we just get a 2nd dose ASAP at 3 weeks?"
No clear answer, but my wife & I WILL WAIT 8 WEEKS for our 5 year-old son.
Brief 🧵. (1/9)
A longer duration between 1st and 2nd doses of Pfizer-BioNTech vaccine has been shown to increase antibody levels and makes COMPLETE SENSE from the immunological perspective given our experience with all other vaccines in both kids and adults. (2/9)
"Hi Alex. What is this Western Canadian variant? Is it something to be worried about?"
Yes, there's a new Canadian AY.25 clade which originated from Idaho. This AY sublineage appears to have become dominant in Alberta and Saskatchewan. (1/9)
This is a bit technical, but as you can see in the phylogenetic analysis below, the strain appears to have originated from Idaho and then spread quickly throughout all of Western Canada. (2/9)
"Hi Alex. My 11 year-old is ready to get vaccinated. BUT, he/she turns 12 in less than a month. Should I wait and get the higher 30 μg dose of vaccine at age 12, or just go ahead & give the lower 10 μg dose right away?"
Answer: DON'T wait, go right away.
🧵 below. (1/7)
The appropriate dosing of vaccine ISN'T dependent on weight, but rather their age. The immune system of a 'small' 11 year-old is functionally the same as a 'large' 11 year-old. The immune response isn't weight-dependent, per se. (2/7)

"Hi Alex. If vaccinated folks can transmit #COVID19 like unvaccinated folks, why get vaccinated? Negative testing is good enough!"
Fully vaxxed persons transmit #COVID19 at FAR LOWER LEVELS than unvaxxed persons. Rapid antigen testing has limitations.
🧵 below to explain
If you're fully vaccinated, your chances of getting #COVID19 infection are MUCH lower, so your chances of transmitting are ALSO much lower too.
If you're fully vaccinated but still get #COVID19, you clear the virus MORE quickly, so you're less contagious overall.

"Hi Alex. Do #COVID19 vaccines affect fertility? Should I get it if I'm pregnant?"
There's SO MUCH misinformation about how COVID-19 vaccines aren't safe in pregnancy or can affect fertility. THIS IS NOT TRUE.
Excellent link 👇 & short 🧵.
All the information we have with billions of doses of #COVID19 vaccine given is that there's NO EVIDENCE that COVID-19 vaccines affect fertility at all.
Every person, whether actively trying to conceive or just thinking about conceiving, SHOULD be vaccinated.

The benefits of vaccinating ALL children b/w ages 5-11 with Pfizer #COVID19 vaccine OUTWEIGHS known or potential risks.
A long-ish 🧵 on data & risk/benefits thus far.
As an ID physician, I'll vaccinate my 5 year-old w/ confidence, and recommend to others to do the same.
#COVID19 is a serious infection for all kids.
Although kids who acquire COVID are at much lower risk of death than adults, other complications can occur after recovery from acute infection, including Multisystem Inflammatory Syndrome (MIS-C), and Long #COVID.

A LONG explanatory 🧵 on ICU 'capacity' & 'flow' in Saskatchewan & why we need MULTIPLE interventions to avoid compromised care for ALL #SK citizens & triage.
I'm going to use an analogy of ICU capacity = bathtub. Patients = water. Health care system = house.
Water is running into the bathtub. That's all the patients who need ICU care in Saskatchewan. Some have COVID, some don't. The patients have now overflowed our ICUs.
To cope, we've built walls up on our bathtub to hold more water. That's our 'surge' capacity.
Summary 🧵 of last night's SHA "town hall" for MDs:
- Overall #SK test positivity ~14%
- Cases declining, but so is testing
- #SK has HIGHEST current case & death rates of all provinces
- HIGHEST ICU census per capita of ANY province at ANY point in pandemic.
Vaccine & mask mandates have helped, but not enough. #SK remains in exponential growth & cases NOT coming down at this point.
Public health experts @SaskHealth recommend gathering restrictions, including limits on household gatherings, capacity limits, etc.
This is an explanatory 🧵 on ICU capacity in Saskatchewan, the different levels of ICU care & support provided across #SK, and why freeing up ICU beds in Regina & Saskatoon is SO important right now for us.
Put plainly: "not all ICU beds are equal"
Not all ICU "beds" are created equal. There's different capability levels to provide support for complex patients depending on the expertise of available doctors, nurses, respiratory therapists, and specialist support. (2/n)
