> Heart Problems After Covid Are Much Worse for the Vaccinated, Nature Study Shows It might as well be that those who are vaccinated and still get sick are just predisposed to heart complications. Saying they get those because they were vaccinated is a fallacy.

No, it's based on a study with a sample size of 42 million. See https://www.medrxiv.org/content/10.1101/2021.12.23.21268276v...

(Argues so poorly that it doesn't really deserve a response, but I'll follow this digression)

If someone is in poor health, they may be

A) more likely to get COVID, despite being vaccinated, AND

B) more likely to have heart problems

In turn, it doesn't matter what the sample size of your study is. A & B will be correlated, even though there's no causal relationship between vaccination+covid->heart problems; the causal relationship is between "poor health" and "heart problems".

This is interesting to contrast with the numerous studies mentioned here: https://www.statnews.com/2021/05/14/setting-the-record-strai...

This is how Science work old studies and new studies can come to contrast conclusion. Why? Because of time, better understanding, more data and many more facts. So yeah we will probably see more long covid problems in the next 2 years.

I love when someone understands and summarizes the scientific method in so feew words. Thanks.

COVID and the autoimmune response to it damages the endothelial layer of your cardiovascular systems. https://www.ahajournals.org/doi/10.1161/ATVBAHA.121.316101 and https://www.nature.com/articles/s41392-021-00819-6 The big question is how quickly and completely can that layer restore itself? If damage accumulates over time and people are catching new variants every 3-4 months it is only a matter of time before morta…

I had Delta once. Prior to it I would ride 30 miles on my bike like it was a breezy day. When I'd take breaks to vacation or whatever I could pick back up easily. A year after COVID, I'm struggling to hit 20 miles and I lose my progress easily. I'm not sure it's COVID related, but nothing else has changed in my life.

We got rid of the control group, I wonder if that was smart.

Control group here. My heart is perfectly fine and I got symptomatic COVID 2 times.

Also control group here.

Early 50's, caught original (& symptomatic) Rona early on. Heart seems fine.

Son (also control group) caught COVID recently, recovered, heart seems fine.

Wife had a vaccine so not in the control group - had an adverse reaction to it and stopped at jab #1.

We're trying to isolate just one single claim. A claim about myocarditis alone. An article saying that the vaccine reduces complications overall, and is therefore a good choice, does not address the question of myocarditis in particular, and if it is reduced in the vaccinated population.

The rate of myocarditis is much higher if you get Covid than if you get the vaccine . So indirectly getting vaccine will lower your risk since of heart disease as everyone will eventually get covid.

> The rate of myocarditis is much higher if you get Covid than if you get the vaccine . What are you basing this on? There was a recent UK study (preprint, last I checked) of 40 million people that showed that the risk of myocarditis was definitively higher compared to Covid in the Moderna sample and higher (albeit statistically insignificant) in the Pfizer sampler for young men. > So indirectly getting vaccine will…

Exactly why, after this was found out, young people were vaccinated with Pfizer and not Moderna

If I'm reading Figure 5 right in the original paper*, it looks like the biggest cardiac impact is on people who were hospitalized or went to the ICU for covid, and the effect on people who were not hospitalized is present but relatively small. Am I interpreting the data correctly?

As I read the text of the study (https://www.medrxiv.org/content/10.1101/2021.12.23.21268276v...) it directly says: "First, we confirm and extend our previous findings in more than 42 million persons that the risk of hospitalization or death from myocarditis following COVID-19 infection is higher than the risk associated with vaccination in the overall population." Is it another study you have where the risk [] is higher after Moderna/Pfizer than after COVID?
