Thimerosal!?

Aluminum!?

Formaldehyde!?

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! 🐟

Cases in many parts of Canada are on the rise 😩

Yes, because of a more infectious sub-variant (Omicron BA.2), relatively low booster coverage, and relaxing protection measures: health-infobase.canada.ca/covid-19/epide…

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.

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?

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).

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.

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.

🧵[1/13]

#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.
