Polyethylene glycol!?

There’s lots of misinformation about these vaccine ingredients, so let’s spend some time finding out what’s safe and what’s not. 👇🏿

It’s a form of mercury that stops microbes from growing in some vaccines. 🛑

It hasn’t been used in routine kids’ vaccines in Canada since 2001, but is in some flu shots.

The mercury dose is less than a can of tuna! 🐟

When it comes to routine vaccines, stick to the schedule. It’s better that way. 📅

Cases in many parts of Canada are on the rise 😩

And, because testing is so limited right now, most case graphs tell only part of the story.

So what do we do about it?


🧵 [1/10] How do we respond to rising... First of all: Are cases really going up?

Yes, because of a more infectious sub-variant (Omicron BA.2), relatively low booster coverage, and relaxing protection measures:…

People don’t just wake up one morning convinced “globalists run the Internet.” 👁️

To get to that point, they need to travel down the rabbit hole. 🕳️

So what drives people towards conspiracy theories and extremism?

A recent safety report by Pfizer has been seized upon by misinformers. There’s nothing particularly new or scary about it, despite the #Pfizer #VaccineSideEffects hashtags circulating online.

Let’s dig in on how this data has been misrepresented 👇


#ScienceUpFirst A screenshot of the cover p... Part of the mix up comes from a misunderstanding of “adverse events”.

Adverse events (AEs) ≠ side effects

AEs may or may not be related to a treatment (e.g. vaccines) and they are monitored for both treatment groups and placebo groups.

COVID isn’t over. We know that’s not what anyone wants to hear right now, but it’s true. 🤷🏽‍♂️

So what is endemicity, and what will it take for us to get there?

Read on to learn more 👇


🧵 [1/12] Is COVID-19 endemic?  A lot... What is an endemic disease? 🤔

A single definition of “endemic” is tough to pin down (1). But epidemiologists say it’s when the rates of a disease are constant - not rising and not falling (2).

Reality: COVID-19 vaccines are not responsible for an HIV variant circulating in the Netherlands. A misrepresented study actually says the variant likely emerged in the 1990s.

Misinformers often present only 2 choices. This or that.

But two seemingly opposite ideas can be true! 🤝

Come with us on a journey across the pandemic’s most popular false dichotomies. 🗺️ And learn how the world is more nuanced than this vs that.


🧵 [1/8] Three circles overlap, red,... Why bother with masks if you have the vaccine? 💉

Protecting yourself isn’t an either/or situation.

Both vaccines AND masks help protect you and everyone around you from disease. Who doesn’t want that?

No vaccine is perfect. That includes the COVID-19 vaccines.

But they don’t need to be in order to save millions of lives.

A thread about transmission 👇

🧵 [1/11]

#ScienceUpFirst We keep hearing, “Vaccines don’t stop transmission”  T Transmission is the passing of a disease-causing pathogen (like a virus) from an infected person to someone else.

COVID-19 vaccines directly and indirectly reduce the transmission of COVID-19.

Beware of the fake news trap! 🕳

Last month we put out a series of Misinformer Tactics in collaboration with the amazing illustrator Jordan Collver (@JordanCollver).

Here is a recap of what to look out for 👇

Similarly, Astroturfing is a practice where a message *appears* to have authentic grassroots support… but is really operated by just a few individuals.

Anecdotal reports find reinfections happening weeks apart. Experts expect it is possible to catch Omicron more than once. Scientists are currently assessing how often reinfections occur and who is at most risk.

“Should I get Omicron and just get it over with?”

NOPE! 🙅‍♀️

We’ve heard this line of thinking from our friends and family. But we’re here to tell you that getting COVID-19 isn’t inevitable and now isn’t the time to throw our hands in the air.

We’re here to set the record straight on spike proteins.

Here’s why the spike proteins generated via the vaccine are safe, activate an effective immune response, and are *not the same* as the spike on the virus.


#ScienceUpFirst Misinformation continues to spread about spike proteins. Let First, a little Spike Protein 101

Spike proteins live on the surface of SARS-CoV-2

The virus infects human cells by binding to receptors. Once attached, the spike protein changes shape, letting the virus infiltrate our cells.

Health Canada approved the Pfizer-BioNTech vaccine for kids 5-11 today. 🥳

NACI has also provided recommendations on how best to use the vaccines, including dose interval.

Let’s discuss why they recommend at least 8 weeks between doses.
