Study: COVID-19 vaccination protects against serious cardiovascular disease - Published Oct 1, 2024

Full vaccination against COVID-19 protects recipients from serious cardiovascular disease linked to COVID-19, according to a new study in the European Heart Journal.
The findings come from a review of more than 8 million adults in Sweden who were followed up in national healthcare registers from the end of December 2020—when COVID-19 vaccination began—until the end of 2022.
Among the 8,070,674 adults included in the study, 88.5% received at least one dose of vaccine, 86.9% at least two, and 67.9% three or more. There were 1,668,508 new cases of COVID-19; 40.3% occurred before the first dose of vaccination, 3.7% between the first and second dose, 34.3% between the second and third dose, and 21.7% after the third dose.
Outcomes included inflammation of the cardiac muscle or the pericardium, cardiac arrhythmia, heart failure, transient ischemic attack (TIA), and stroke.
Individual vaccine doses linked to increased risk
Overall, vaccination was associated with decreased risks of cardiovascular disease by about 20% to 30% compared to no vaccination.
The authors note, however, that some cardiovascular effects have been seen after individual doses of the vaccine, especially among older men.
There was a 17% higher risk of extrasystoles, or extra heart beats, after dose one and 22% after dose two. While the overall the risk of stroke was lower in vaccinated people, there was an increased risk of TIA.
"It should be noted that for outcomes showing slightly increased risks (myopericarditis, TIA, and extrasystoles), the incidence rates were generally lower than for the other outcomes that showed decreased risks," the authors said.
"The increases in cardiovascular risk we saw following COVID-19 vaccination are temporary, and do not apply to the more severe conditions," said study author Fredrik Nyberg, PhD, in a press release from the University of Gothenburg. "On the other hand, full vaccination significantly reduced the risk of several more severe cardiovascular outcomes linked to COVID-19, such as heart attack, stroke, and heart failure. This emphasizes the protective benefits of full vaccination."
