Someone receives a vaccine.

Three days later they have a heart attack.

Someone else develops Bell’s palsy. Another has a seizure. Another dies unexpectedly.

Those events matter.

But there is one question we must answer before deciding the vaccine caused them:

How often would these events have happened anyway?

A thread about BACKGROUND RATES—and one of the most important concepts in drug and vaccine safety. 🧵

Science depends on skepticism.

But skepticism is not the same as refusing every possible answer.

One of the fairest—and most revealing—questions we can ask in any scientific disagreement is:

“What evidence would change your mind?”

A thread about evidence, belief and intellectual honesty. 🧵

@EmpiricGame Planning to cover this study on #SGEMPeds. Suffice it to say...I'm quite skeptical of these findings. Also they keep equating odds with risk... @TheSGEM

[Dennis Ren MD @DennisRenMD]

Time to hear from you #SGEMPeds audience. What are you using to guide pulmonary embolism work up in pediatric patients? https://t.co/IsT2vUuPBo @TheSGEM @PECARNteam @LWestafer

[Dennis Ren MD @DennisRenMD]

Did you know there's a new modified tool for identifying children at low risk for pulmonary embolism? #MemeMonday #SGEMPeds @PECARNteam @LancetRespirMed @TheSGEM @LWestafer https://t.co/IsT2vUuPBo
