A study led by Professor Daniel Prieto Alhambra the study found that COVID-19 vaccines proved to be highly effective in reducing the severity of acute SARS-CoV-2 infection, COVID-19-related hospital admission and death. It also proved that The risk of cardiac and clot-related complications following COVID-19 is substantially reduced in people who receive the COVID-19 vaccination compared with unvaccinated individuals.
Authors of the study analyzed 10.17 million vaccinated people and 10.39 million unvaccinated people. The results illustrate that COVID-19 vaccination was associated with reduced risks of heart failure, venous thromboembolism (clot within the veins of a limb) and arterial thrombosis/thromboembolism (blood clot in the artery) for up to a year after SARS-CoV-2 infection.
Reduced risk of other complications, such as ventricular arrhythmia or cardiac arrest (heart attack), myocarditis and pericarditis were also seen, but only in the first 30 days after infection.
Compared with unvaccinated individuals, having a COVID-19 vaccination was associated with reduced risks of venous thromboembolism by 78%, arterial thrombosis/thromboembolism by 47% and heart failure by 55% in the first 30 days after SARS-CoV-2 infection. However, as time progressed the protective effects of vaccination waned.
As time progressed, the protective effects of vaccination waned, but remained at 47%, 28%, and 39% respectively at 91–180 days after infection and 50%, 38%, and 48% respectively at 181–365 days.
