Earlier today, @PremierScottMoe posted a letter. In it, he stated:

- Being vaccinated DOES NOT prevent one from contracting #COVID19
- Vaccines are NOT reducing transmission of #COVID19

Both statements are FALSE & should be corrected ASAP for the record. Thank you.

Many studies show 3 doses of mRNA vaccine (Pfizer or Moderna) provides 60-70% protection (vaccine effectiveness, VE) vs Omicron infection.

If you don't get infected, then you don't transmit the virus. Simple.

So being vaccinated, esp. w/ 3 doses, makes a HUGE difference. (/2)
Here is a recent pre-print from Moderna showing ~68% VE against Omicron infection with 3 doses of vaccine.

Also, VE to prevent hospitalization w/ Omicron following 3 doses was >99%. That's HUGE. (/3)

medrxiv.org/content/10.110…
Here is Canadian pre-print data published yesterday from colleagues in #ON showing ~61% VE against Omicron infection with 3 doses of vaccine.

More importantly, 95% reduction in severe illness with 3 doses of vaccine. Again, HUGE. (/4)

medrxiv.org/content/10.110…
Another recently published study in JAMA showing that having 3 doses of mRNA vaccine significantly reduces (by about 2/3rds) the likelihood of testing positive w/ Omicron vs. being unvaccinated or having 2 doses of vaccine. (/5)

I could keep posting endless studies, but you get the idea.

Even though Omicron IS far more contagious compared to previous variants, 3 doses of vaccine makes a REMARKABLE difference BOTH in reducing your chances of being infected (~60-70%) AND getting really sick (95%+). (/6)
As we navigate Saskatchewan's Omicron surge, the scientific evidence AND public health guidance BOTH point OVERWHELMINGLY to a focus on getting as many persons optimally vaccinated with 2 or 3 doses as we can.

We must protect our already overwhelmed health care system. (/7)
Earlier this week, Premier Moe labeled peer-reviewed work from @MoriartyLab "egregious misinformation".

Tara's work, rigorously done & reviewed by the likes of @DFisman, suggests #SK's death toll from #COVID19 is several times higher than reported. (/8)

thestarphoenix.com/news/local-new…
Our Premier asked our media outlets to retract their stories regarding Tara's work.

Oops. Tara's work isn't "misinformation". It's actual SCIENCE.

Now, ironically, our Premier is dangerously undermining the #SK vaccine push by circulating false information on vaccines. (/9)
Courtesy @Craig_A_Spencer, here's the INCREDIBLE real-world efficacy of vaccination on cases, hospitalizations, and deaths in New York City.

Pictures are worth literally millions of words. (/10) ImageImageImage
Lastly, if you want even more data, here's a SUPERB thread on vaccine effectiveness against Omicron from #SK's own @angie_rasmussen that summarizes pretty much everything as only she can, with a unique combination of sass, wit, and knowledge. (/11)

I hope our Premier corrects these statements ASAP. #SK citizens listen to every word he says.

It would be very unfortunate if they assumed that vaccines don't do what we know they do, because of this "misinformation", whether accidental or otherwise. (/12)
In summary:

Being fully boosted DOES significantly reduce the chances of getting infected w/ Omicron.

Vaccines DO reduce transmission of Omicron.

Vaccines DO keep nearly everyone out of hospital & ICU.

For yourself & those around you, get fully vaccinated!

Be safe.

Latest wastewater data for #SK communities was released earlier today. It's NOT good.

Let's work through what has been going on over the last couple of weeks as BA.2 has taken complete hold across Saskatchewan.

Short 🧵 - here we go. (1/7)
Regina & Saskatoon have seen HUGE increases in wastewater viral burden since early April. It's all driven by the more contagious BA.2 Omicron variant.

@LaurenPelley tweeted last week as Saskatoon's viral burden increased an astonishing *742%*. (2/7)

As of Apr 13, Saskatoon's viral burden has increased by yet another 25%, setting a new historic record once again. Nuts.

Viral burdens are TRIPLE that of the worse levels seen with Delta last Fall. It's all BA.2 - 99.3% now. The tiny 0.7% remaining is BA.1. (3/7)

Between February 1-26, 143 Saskatchewan citizens have died from #COVID19, despite Omicron being "less severe".

That's an INSANELY high number.

Saskatchewan's most deadly month thus far was October 2021, when 156 people died during our horrific Delta wave. /1
As highlighted by @DrKyle, Saskatchewan's death rate from #COVID19 is more than DOUBLE that of the 2nd highest province, Manitoba.

No province is even remotely close in terms of deaths per capita at this point with Omicron. So embarrassingly bad. /2

With 2 days left, February 2022 might not technically be Saskatchewan's deadliest month during this pandemic, but remember... there's only 28 days in February vs 31 days in October.

If you pro-rate 5.5 deaths per day (February 2022's deaths per day) x 31 days? *170* deaths. /3

Hi, Saskatchewan.

Though @SKGov has now dropped all #COVID19 protections & mandates, sadly, COVID is NOT over.

#SK hospitals & ICUs remain packed.

Patients are being admitted, and dying, tragocally, eacn and every day.

A short 🧵 below for my fellow Saskatchewanians. /1
Please, be mindful of our medically vulnerable, kids under 5 who can't be vaccinated, the elderly & frail. Those who will and already face long COVID.

Respect their health and their right to live their lives as fully as possible in a manner that is safe & low-risk. /2
If your immediate response for those who are vulnerable to or anxious of COVID is, "well, just stay home"?

Remember how you felt when "others" said the same to you about mask mandates or proof-of-vaccine programs.

Let's end the divisiveness. Let's do things TOGETHER, safely. /3

Weekly Saskatchewan COVID-19 data for Feb 13-19.

KEY POINTS:
- 37 deaths over 7 days. 1 b/w 20-39, all others >= 40
- Hospitalizations & ICU admissions decreasing (phew)
- Weekly test positivity 14.4% (last wk ~20%)
- ALL Omicron (no breakdown of BA.1 vs BA.2)

Brief 🧵 /1
Let's start with key data around hospitalizations & ICU admissions.

Week-by-week hospitalizations down 9% to 372, ICU down 18% to 27. Slowly coming down, thankfully.

Of those with known COVID status, 42% in hospital/ICU "due to COVID", 58% "incidental". /2
We can see that overall hospital admissions per day definitely decreasing now across all regions of Saskatchewan, but it's a relatively slow decrease, likely driven by limited protections we have in place provincially.

Still, this is reassuring and encouraging. /3

Saskatchewan #COVID19 wastewater data released today for 4 #SK communities.

Both Saskatoon & Regina showing significant INCREASES in viral load week over week. Discouraging.

Reasons for increase unclear at this time. BA.2 driven?

Brief 🧵 to review #SK wastewater data. /1
Let's start with Regina.

@UofRegina wastewater analysis shows rebounding viral load levels week-over-week, suggestive of ongoing high rates of viral transmission in community.

BA.1 remains dominant but 18% BA.2 reported too. We expect BA.2 to dominate in coming days. /2 Image
Also, note that @UofRegina plot is time-lagged by 13 days, as the most recent analysis comes from the time period b/w Feb 6-12 inclusive.

So presumably proportion of BA.2 in Regina is higher now, just don't know how much higher. /3

"Hi Alex, what's BA.2? Is it a little bad or is it REALLY bad?"

BA.2 is a sub-lineage of Omicron. The 'original' lineage of Omicron is designated as BA.1 & remains the dominant strain circulating in most parts of Canada currently.

A brief 🧵 of what we know thus far. /1
BA.1 & BA.2 are both classified by @WHO as Omicron, but are distinct viruses. See the phylogenetic diagram below (thx @kallmemeg).

BA.2 has over 25 mutations that differentiate it vs BA.1.

Many questions still exist around how similar BA.1 & BA.2 are clinically. /2
Danish pre-print data comparing transmission of BA.1 vs BA.2 in household settings suggests BA.2 IS more transmissible than BA.1.

BA.2 also LIKELY possess more immune-evasive properties vs BA.1 that could reduce vaccine efficacy. /3
