Popis: Since universal vaccinations represents the most effective strategy to mitigate coronavirus disease 2019 (COVID-19), baseline assessment and post-vaccine monitoring of anti-SARS-CoV-2 neutralizing antibodies are essential to vaccination programs. Therefore, this study aimed to compare data of five commercial anti-SARS-CoV2 immunoassays after administration of an mRNA vaccine.Venous blood was collected from three healthcare workers, receiving a double (30 g) dose of BNT162b2 mRNA Covid-19 vaccine (Comirnaty, Pfizer), on the day of the first vaccine dose and then at fixed intervals for the following 2 months. Anti-SARS-CoV-2 neutralizing antibody response was assayed with Roche Total Ig anti-RBD (receptor binding domain), DiaSorin TrimericS IgG (spike trimer), Beckman Coulter IgG anti-RBD, SNIBE IgG anti-RBD and Technogenetics IgG anti-N/S1.A total number of 45 samples were drawn at the end of the 2-month study period. The Spearman's correlations of absolute anti-SARS-CoV-2 antibodies were always excellent (all p0.001), comprised between 0.967-0.994. Satisfactory results were also observed when absolute antiSARS-CoV-2 antibodies values of the five methods were compared with the mean consensus value, with correlations always higher than 0.979 (all p0.001). The agreement of anti-SARS-CoV-2 antibodies positivity versus the consensus median positivity ranged between 0.764 and 1.000 (always p0.001), but become always0.900 after readjustment of one assay cutoff.All the immunoassays evaluated in this study appear suitable for monitoring anti-SARS-CoV-2 neutralizing antibodies response in subjects undergoing mRNA COVID-19 vaccination.Pošto univerzalna vakcinacija pretstavlja najefikasniju strategiju za zaustavljanje koronavirus oboljenja 2019 (COVID-19) veoma je važno praćenje nakon vakcinacije anti-SARS-CoV-2 antitela koja su va`na za programe vakcinacije. Iz tog razloga ovo proučavanje je imalo za cilj da poredi podatke pet komercijalnih anti-SARS-CoV-2 imunodređivanja nakon davanja mRNA vakcine.Uzeta je venska krv od tri zdravstvena radnika koja su primila duplu dozu (30 g) BNT-162b2 mRNA Covid-19 vakcine (Comirnaty, Pfizer) odmah nakon davanja prve doze vakcine a zatim u fiksiranim intervalima u roku od sledeća 2 meseca. Anti-SARS-CoV-2 neutrališuća antitela su određivana sa Roche Total Ig anti-RBD (receptor vezujući domen), DiaSorin TrimericS IgG (spike trimer), Beckman Coulter IgG anti-RBD, SNIBE IgG anti-RBD i Technogenetics IgG antiN/S1.Nakon 2 meseca uzeto je 45 uzoraka. Spearma - nova korelacija apsolutnih anti-SARS-CoV-2 antitela bila je uvek odlična (svi p0,001) sa obuhvatom između 0,967-0,994. Zadovoljavajući rezultati su dobijeni između vrednosti apsolutnih anti-SARS-CoV-2 antitela dobijenih sa svih pet metoda kad su upoređivane sa konsenzus vrednostima i korelacijom koja je bila veća od 0,979 (svi p0,001). Slaganje pozitivnosti anti-SARS-CoV-2 antitela prema konsenzus srednjoj pozitivnosti koja se kretala između 0,764 i 1,000 (uvek p0,001), bila je uvek0,900 nakon podešavanja cutoff vrednosti za jedno određivanje.Sva imunodređivanja koja su procenjivana u ovom izučavanju su pogodna za praćenje anti-SARS-CoV-2 netralizirajućih antitela koja nastaju kod osoba koja su bila vakcinisana sa mRNA COVID-19 vakcinom.
