The aim of this study is to determine the frequency of adverse events of COVID-19 vaccination in patients with SLE who are attended at referral medical centers in Paraguay. This is an observational, cross-sectional, descriptive study. Fifty-two patients with SLE who received at least one dose of anticovid vaccine were included. Of which 100% received the first dose, 92.3% the second dose and 15.38% the third dose; 44.6% received SputnikV; 16% Moderna; 12.5% Pfizer, 7.1% AstraZeneca, 3.6% Covaxin and 2.1% Hayat Vax, 8 patients received their third dose corresponding to 3 from Pfizer, 3 from Moderna, 2 from AstraZeneca. In the 108 doses applied, a total of 43 adverse events were recorded, 95.3% within the first 5 days and the rest at 5 days. A total of 51.2% presented the adverse event after the first dose, 39.5% after the second dose and 9.3% after the third dose. The mean duration of symptoms was 2.3 days ±1.4. The most important adverse effect was pain at the injection site, followed by fever and fatigue. Exacerbation of SLE was also recorded as an adverse event in 8.3%. Mild adverse effects were recorded, it is concluded that vaccination against covid 19 is safe for patients with SLE.
