1) Happy Holidays, everyone! Although I will be returning to work on Jan. 4, I wanted to underscore the seriousness of this, the 5th wave of the #COVID19 pandemic in Quebec. In this thread, I will focus on rising hospitalizations among the doubly-vaccinated.
2) First, I can’t emphasize enough the importance of getting vaccinated against #COVID19. The non-vaccinated are nearly 15 times more likely to be hospitalized with #COVID in Quebec than those who have received two shots. But it’s become clear even two shots may not be enough.
3) As the chart below shows, on Nov. 18, the province recorded 17 new #COVID19 hospitalizations. Of that number, a dozen were among the non-vaccinated or those who got a first dose. But five individuals were hospitalized despite two doses. Who were those five?
4) Those five individuals were likely in their late 70s with pre-existing medical conditions and had received their second #COVID19 doses in May or June. Although the life-saving shots are highly effective, research has shown that vaccine immunity wanes over time.
5) In contrast, the most recent chart, dated Dec. 18, reveals that the number of new hospitalizations among those who received two doses jumped to 21. That compares with 38 hospitalizations among the unvaccinated or those that got only one dose.
6) The data suggest that not only are hospitalizations rising among Quebecers who have received two doses, but this group’s percentage of the total number of hospitalizations is rising, too. So was is the impact on intensive care?
7) A month ago, 25 Quebecers who were doubly vaccinated sadly ended up in the ICU during a 28-day period, compared with 70 who were not. Now, a month later, it’s 68 Quebecers doubly vaxxed who ended up in the ICU, compared with 105 who were not.
8) As my @mtlgazette colleague Steve Faguy (@fagstein) pointed out today, “hospitalizations are up 20% in two days. There are 27% more in ICU than two days ago. If these were to continue, hospital capacity would be exhausted in 10 days.”
9) Faguy’s astute warning follows projections this week by the Institut national d'excellence en santé et en services sociaux (INESSS) predicting “a marked increase in the number of daily hospitalizations over the next few weeks.”
10) On Saturday, Premier François Legault disclosed that about 20% of recent screened #COVID samples turned out to be the super contagious Omicron variant of concern — much higher than authorities expected. This aerosolized variant is likely driving Quebec’s fifth wave.
11) The implications of this fifth wave are two-fold: Quebecers must return en masse to #PhysicalDistancing and avoid large gatherings. The government must also mobilize even more quickly to deliver the third booster shots to the adult population.
12) At the same time, it’s worth pointing out that many people in developing nations haven’t even received their first shots. Such is the horrific imbalance of this #pandemic on its second anniversary. End of thread. Stay safe, everyone.

1) Quebec on Wednesday fell from second to third place in its #COVID19 vaccination rate among provinces, behind British Columbia. Surprisingly, Ontario is now in first place among provinces, as the chart below indicates.
2) What’s more, nearly 24% of Ontario’s population is fully vaccinated compared with 18.86% in Quebec. Clearly, Quebec has a lot more to do to find ways for younger adults to get vaccinated, including the possibility of paid leave to workers seeking second shots.
3) Despite lower-than-expected vaccinations and #COVID19 testing, Montreal continues to report reassuring numbers under the direction of its apolitical head of public health, Dr. Mylène Drouin. The chart below shows a decrease of 30 #COVID19 outbreaks in the city since last week.

1) Quebec on Tuesday fell from first to second place in its #COVID19 vaccination rate among provinces, ceding the coveted spot to British Columbia. This reflects the fact that Quebec has been struggling to encourage younger adults to go get their shots. Image
2) On Tuesday, Quebec Premier François Legault again suggested a vaccine lottery for those who have been immunized fully, but there are other incentives that might be more effective, like giving workers a paid time off to get their shots, as other provinces are doing.
3) As things now stand, at least 17.79% of Quebec’s population has been fully immunized and 70.3% partially. At the current rate of 600,000 vaccination a week, it would probably take another nine weeks to fully vaccinate most of the province’s population.

1) Quebec Premier François Legault floated the idea on Monday of a vaccine lottery to encourage younger adults to get their #COVID19 shots, this after a relatively low 57,000 doses were administered in the province on Saturday. montrealgazette.com/news/quebec/qu…
2) Although Quebec is facing a delay in a Pfizer shipment that was supposed to be delivered over the weekend (and will arrive instead on June 24 or June 25), the latest stats show that Quebecers aged 18 to 29 still trail other demographics, including 12 to 17-year-olds.
3) With the province opening up this summer and #COVID19 variants circulating, full vaccination is critical. But on Monday, just 16.87% of Quebec’s population was fully immunized, up from 16.25% the day before. Quebec can and should do much better.

1) Quebec on Friday reported five more cases of the feared P.1 variant, including a single case for the first time in the Capitale-Nationale region. In this thread, I will provide an update on the more transmissible variants circulating in the province.
2) The P.1 variant has been responsible for the massive third wave in Brazil that has caused tens of thousands of #COVID19 deaths. But to date, Quebec has reported 30 confirmed cases of P.1. That compares with 645 in Ontario, 944 in Alberta and 2,063 in British Columbia.
3) The predominant variant by far in Quebec is B.1.1.7. Quebec’s public health institute reported 364 more sequenced cases of B.1.1.7., which was first detected in the U.K. Montreal continues to post the highest number of B.1.1.7 cases in the province.

1) Even as Quebec has made laudable progress in reducing the number of #COVID19 hospitalizations while ramping up vaccinations, hot spots remain — a warning that the #pandemic will probably continue here for months to come. In this thread, I will examine some of those hot spots.
2) As of Wednesday, 35% of Quebec’s population had been partially inoculated and 3.69% had received the second dose. Federal guidelines recommend vaccine coverage of 75% with one dose and 20% with two doses to achieve collective immunity.
3) Among the potential #COVID19 hot spots are hospitals and eldercare homes. Emergency-room workers at St. Mary’s Hospital received their first doses of the Pfizer vaccine in January, and 18 still got infected in an outbreak. montrealgazette.com/news/local-new…

1) In my Twitter thread yesterday, I wrote about how Montreal has continued to defy the odds in the third wave. But that doesn’t mean the #pandemic is over in the city — far from it. In this thread, I will highlight some lingering problems.
2) First, the number of #COVID19 outbreaks in the city inched up by four to 281 since last week. What’s more, the majority involve the more transmissible variants. Still, the head of the Montreal public health department cautioned that the clusters are small. See the chart below. Image
3) And although #COVID19 outbreaks decreased in the workplace in Montreal since a week ago, they increased in grocery stores. Clusters also went up in both health-care institutions and schools, likely fueled by the variants. Please take a look at the chart below. Image
