@drzackmd: Large-scale cohort data published in JAMA Internal Medicine demonstrates that updated COVID-19 vaccination is associated with a significant reduction in major adverse cardiovascular events. Studying over one million United States veterans, researchers identified an approximate thirty percent decrease in the composite risk of acute myocardial infarction, ischemic stroke, and all-cause cardiovascular mortality among vaccinated individuals. SARS-CoV-2 infection induces profound systemic endothelial inflammation, prothrombotic microvascular cascades, and plaque destabilization. Mitigating acute viral inflammation with vaccination directly reduces downstream ischemic vascular injury. #DrZackMD #Cardiology #InfectiousDisease #PublicHealth #EvidenceBasedMedicine

Bobbi 💋 :

I’m saving this for the holidays for my maga family members. 🤣🤣🤣🤣

Kelly Gregory :

I got pericarditis. From Covid. I always get the shot now.

Pharmy2012, PharmD, CSPI :

Scared me for a sec there 😅

Marsutho :

Almost scrolled past your video…😂 Thanks for real science.

Fud :

You’ve referenced cervical manipulation and stroke with the same anecdotal “evidence” that you seem to dismiss for the vaccine.

jeremyluce495 :

Another “southern accent means stupid person”

Drepmd :

I don’t know if you know but a stroke isn’t a “cardio thing” it takes place in the brain

StatisticianProper :

Ooooofff I thought I was in enemy territory. Proceed Doc…

One World Health :

Don’t argue with Dr Zack… he is way too smart 🥰

Dan_Of_All_Trades :

I'm becoming a huge fan of yours. when I looked at the study.It seemed to say that just the shots that were given in 2024 to 2025 reduced the likelihood of a stroke if the person has or had contracted covid. it dud not state that if you get the shot , you have a smaller chance at a stroke. am I reading this correctly?

Sarah Parsons :

Say it for the people in the back.

RNKARA :

I’m not a conspiracy theorist, but as a floor nurse as a hospital, I have to wonder why “Code Stroke” comes overhead on the speaker 8-9 times per day, when prior to the vaccine we maybe heard it 3-4 times per day…but this helps ease my mind, as I also received the vaccine, so thank you 😊

Go Birds :

What’s the study?

Jeremiah Johnson :

I had this conversation with an actual nurse the other day. Then I had to explain "anecdotal".

Nicole Douglass :

Curious, is it causative or correlative? Just bc quick look at screengrab there looks like data came from more recent vaccines, by which time the only folks who are probably still getting them may/may not have great cardiovascular health to start (older, generally sicker, but pro-vaccine generally?). Admittedly lots of generalizations on my part. I have gotten the covid vax every year they’ve been available. Haven’t gotten the most recent one yet because I have to space it for a time when I can take a few days off. I get the WORST body aches from it. Beats intubation every time though!

chigirl312 :

I love science!

Tombuzz :

I was worried at the beginning

LAZERBEANZ :

Danny Plunkett847 :

People who don’t want to believe it won’t and will continue to hold to the weak studies that show harm from the vaccine. Dealing with it in my family. I printed out the study but they refuse to read it.

dogmom :

that's amazing.

studywithmadison :

I’ll take that reduced risk babyyyyy

leern90 :

Almost blocked you there Dr Zack! lol

crystalclearday :

Which COVID vaccine? There are several different types.

ShawnE :

Imagine that
