Tóm tắt

The comparative safety profile of SARS-Cov2 vaccines requires further characterization in real-world settings. The aim of the VigilVacCOVID study was to assess the short-term safety of BNT162b2 and mRNA-1273 during the vaccination campaign of healthcare professionals (HCPs) and solid-organ transplant recipients (SOTRs) at a hospital clinic. We conducted an observational, prospective, single-center, post-authorization study to characterize short-term adverse reactions (ARs) after vaccination. The primary endpoint was to assess between-vaccine differences (HCPs receiving BNT162b2 or mRNA-1273) and between-population differences (HCPs and SOTRs, both receiving mRNA-1273) in the risk of any ARs. Propensity score and covariate-adjusted multivariate models were used. The key secondary endpoint was to provide a descriptive assessment of the frequencies and intensity distribution of ARs. We included 5088 HCPs and 1289 patients. mRNA-1273 showed greater reactogenicity than BNT162b2, with an odds ratio (OR) for any AR of 3.04 (95% confidence interval (CI) 2.48–3.73; p value: < 0.001) and a higher frequency and intensity of reported ARs. Compared with HCPs vaccinated with mRNA-1273, SOTRs showed a lower risk of ARs (OR = 0.36; 95% CI 0.25–0.50), with fewer and less severe ARs. Age, sex, and previous SARS-CoV-2 infection were statistically significant covariates for the risk of any AR. A history of drug allergy was significant in the comparison between vaccines (BNT162b2 vs. mRNA-1273), but not in that between SOTRs and HCPs. Our study shows that mRNA-1273 had greater reactogenicity than BNT162b2. Overall, both vaccines had an adequate tolerability profile. mRNA-1273 vaccination caused fewer ARs with milder severity in SOTRs.
