Position paper of the Italian Society of Cardiology (SIC) on COVID-19 vaccine priority in patients with cardiovascular diseases

In over a year, the COVID-19 pandemic caused 2.69 million deaths and 122 million infections. Social isolation and distancing measures have been the only prevention available for months. Scientific research has done a great deal of work, developing in a few months safe and effective vaccines against COVID-19. In the European Union, nowadays, four vaccines have been authorized for use: Pfizer-BioNTech, Moderna, ChAdOx1 (AstraZeneca/Oxford), Janssen (Johnson & Johnson), and three others are currently under rolling review. Vaccine allocation policy is crucial to optimize the advantage of treatment preferring people with the highest risk of contagion. These days the priority in the vaccination program is of particular importance since it has become clear that the number of vaccines is not sufficient for the entire Italian population in the short term. Cardiovascular diseases are frequently associated with severe COVID-19 infections, leading to the worst prognosis. The elderly population suffering from cardiovascular diseases is, therefore, to be considered a particularly vulnerable population. However, age cannot be considered the only discriminating factor because in the young-adult population suffering from severe forms of heart disease, the prognosis, if affected by COVID-19, is particularly ominous and these patients should have priority access to the vaccination program. The aim of this position paper is to establish a consensus on a priority in the vaccination of COVID-19 among subjects suffering from different cardiovascular diseases.
