👩🏾🔬Response to the most common question I got today:
The new variant has a lot of mutations, what does this mean in terms of epidemiology & vaccines❓
🧬 short answer: to early to tell‼️
🔬Long, more nuanced answer: whilst having too many mutations, some of which are known to 1/
affect for instance how fast the virus replicates inside our cells or how it interacts with our immune system, it is difficult to say what synergistic effect all those mutations could have when put together, without functional assays coupled with real-world data‼️ 2/
Analogy: some vegetables on their own taste quite meh, some combination of those vegetables put together could make an absolutely awful meal, but sometimes you add in a bunch of other ingredients & you get something that’s tolerable‼️
(Can you tell I don’t like vegetables 🙃) 3/
All that to say that yes, we must 💯 be vigilant, which is why we have a Coronavirus Variants Rapid Response Network @CoVaRR_Net, but at the moment claims of immune escape, etc. are based on very little evidence. The honest response is we don’t know yet but we will soon 😉 4/
In the meantime, let’s focus on things we know:
📌vaccines ⬇️ transmission & are an important tool in hampering viral evolution #SayYesToVaccines
Hearing the news of Omicron cases in Europe in people who travelled through various countries (Malawi, Egypt, Namibia, Dubai, etc.) indicates that Omicron was flying under the radar in undersequenced countries for some time until Botswana & 🇿🇦 detected it & alerted the 🌎.
The thing about pathogen evolution, particularly in obligate cellular parasites, is that detecting new lineages is difficult unless it is being transmitted AND someone is looking for it (biological samples including wastewater)➡️need capacity building in genomic surveillance
We’re lucky to have good genomics capacity (but always more can be done), many countries do not! We MUST help them develop these capacities so they can be continuously monitoring their regional evolution!!
🔬🧬We are the Coronavirus Variants Rapid Response Network @CoVaRR_Net working to accelerate & facilitate our understanding and management of #SARSCoV2 variants of concern!
Science doesn’t happen in silos & is not one dimensional!
@Covarrnet is founded on the belief that the best science is one that is collaborative & #EDII-centred.
Here are some of the brilliant people who make up @CoVaRR_Net: @langlois_ma@ninan_abraham1@JenGommerman@gingraslab1
This is an extremely difficult time to be a scientist & even more so if you are a minority #WomanInScience.
Last night I went on @globalnews radio thinking I was going to talk about the differences between PCR & other screening methods for COVID—basically science. 1/
The conversation was steered towards border policy & that some want more restrictions to be removed. Doing my duty as a scientist & using the best current evidence, I noted the rise in cases 🌍, the not so perfect💉 rate in some places & importance of using #RapidTest
2/
I then urged my fellow Canadians to be prudent & cautious when making travel arrangements.
The host then made an off-the-cuff remark on how “if I were in charge of making that policy I would probably close the border”—a completely inappropriate misinterpretation of my advice‼️

📊 Ontario Science table’s survey shows significantly lower vaccination intention amongst groups who experience a disproportionate burden of COVID outcomes: low income & racialized.
As someone who belongs to this group & does literacy outreach I’d like to dissect it further 🧵⤵️
1️⃣
This phenomenon isn’t new. In every aspect of medicine, racialized, marginalized, underserved & low-income groups, who often experience the highest burden of bad outcome, also happen to be the most reluctant to seek medical intervention, including vaccination. But why⁉️
2️⃣
Barriers to access is at the root of the issue‼️
These barriers include:
📌 Mistrust
📌 Low health literacy
📌 Financial & logistical burden
1-Today there was a big protest in Montréal by healthcare workers opposed to mandatory vaccination.
As a healthcare professional & a bioethics I want to underline a few points about #VaccineMandates for healthcare provides
🧵👇🏾
2-In bioethics, autonomy is no longer that centuries-old belief that the individual can or does somehow stand apart from their community, social circumstances & political environment. Also, autonomy has a different scope when intervention in question has implications beyond self.
3-Dr Nedelsky(osgoode.yorku.ca/faculty-and-st…) calls the belief that autonomy is isolated from outside influence a “pathology”: “If we ask ourselves what actually enables people to be autonomous, the answer is not isolation, but relationships—with parents,
teachers, friends, loved ones.”
