This study aims to determine the effects of vaccination against SARS-CoV-2 in people with long COVID
The Sociedad Española de Médicos Generales y de Familia (SEMG) and the collective of affected people @longcovidACTS have been working together for months to try to provide answers to those affected by Persistent or Long COVID.
Now they want to go a step further and want to know what the situation is regarding vaccination against SARS-CoV-2 when suffering from Persistent COVID or Long COVID.

More about this Study:
Scientific Context: The increase in COVID-19 infections has made the existence of so-called persistent COVID-19 or « long COVID-19 » increasingly evident. This is the name given to cases where the infected patient has symptoms beyond the approximately 14 days that are considered normal for COVID-19 cases. Although sometimes referred to as sequelae, these are actually symptoms: patients with persistent COVID-19 may experience symptoms four weeks or even months after infection. Symptoms may include coughing, hair loss, fatigue or chest pain.
