1. Data is still emerging on myocarditis post-vaccination and whether it's a consequence of the vaccine or coincidence

At this time CDC/PHAC still encourage vaccination in those 12+

Here's a short thread on what you should know 🧵

(More details here: cdc.gov/coronavirus/20…)

2. When has myocarditis been reported?

Myocarditis after vaccination has been noted
-more commonly with 2nd dose
-usually within a few days after vaccination
-mostly in males, 16+ or older

3. What should you look out for?

Contact your doctor if, within a few days of receiving the vaccine, you or child have
-chest pain
-shortness of breath
-palpitations (fluttering or fast-beating or pounding heart)

4. What should your doctor do if you report these symptoms?

Your doctor should order an ECG (a reading of your heart, that can be done in the office or lab) and also order blood tests (inflammatory markers: troponin and either CRP or ESR)

5. If these tests are normal, it's unlikely you/your child have myocarditis

If the tests show concerns, then you/your child likely need a consultation with a specialist

6. For my MD colleagues, I found this slide from Dr. Allison McGeer's to be really helpful when managing a recent case

7. A reminder that this discussion about myocarditis is happening because our surveillance systems are working

Any adverse event following vaccination needs to be reported to our local public health unit. They do careful reviews to see if there are any concerning signals.

8. Finally, please keep in mind that we are talking about a very rare event

I thought this article by @wencyleung ft @kgrindrod @DavidJuurlink @AnnaBanerji provided a great, nuanced overview
