Summary
New study: COVID vaccines linked to increased coronary artery risk after 2nd Pfizer dose, but 3rd doses showed no increased heart risks. Different vaccines had varying cardiovascular risk profiles.
The story
I just learned about a new Bayesian meta-analysis on COVID vaccines and heart risks that breaks down some important details most people don’t talk about.
The study found COVID vaccines are linked to increased coronary artery disease [CAD] risk, especially after the second dose of the Pfizer vaccine specifically.
Interestingly, they didn’t find an overall increased risk of heart attack, arrhythmia, or stroke from COVID vaccination. Even more surprising, after the third dose, there was no significant increase in risk for any cardiovascular problems, and some outcomes actually showed a protective effect.
Different vaccines had different risk profiles:
– Pfizer: Increased risk for several cardiovascular events [except arrhythmia]
– AstraZeneca: Mainly associated with increased arrhythmia risk after first dose
The timing of doses mattered too:
– First doses: Higher risk of arrhythmia and stroke
– Second doses: Increased risk of heart attack and broader cardiovascular disease
– Third doses: No significant increased cardiovascular risks
The researchers suggest these findings should help guide future vaccine development. It shows how medical interventions can have complex risk profiles that vary by individual circumstances and dosing schedules.
