Major Field of Science: | Medical and Health Sciences | Field Category: | Health Sciences | Keywords: | COVID-19;Healthcare workers;Pandemic;Vaccines | Issue Date: | 9-Aug-2021 | Source: | Vaccine, 2021, vol. 39, no. 34, pp. 4788-4792 | Volume: | 39 | Issue: | 34 | Start page: | 4788 | End page: | 4792 | Journal: | Vaccine | Abstract: | In Italy, the COVID-19 vaccination campaign started in December 2020 with the vaccination of healthcare workers (HCW). To analyse the real-life impact that vaccination is having on this population group, we measured the association between week of diagnosis and HCW status using log-binomial regression. By the week 22-28 March, we observed a 74% reduction (PPR 0.26; 95% CI 0.22-0.29) in the proportion of cases reported as HCW and 81% reduction in the proportion of symptomatic cases reported as HCW, compared with the week with the lowest proportion of cases among HCWs prior to the vaccination campaign (31 August-7 September). The reduction, both in relative and absolute terms, of COVID-19 cases in HCWs that started around 30 days after the start of the vaccination campaign suggest that COVID-19 vaccines are being effective in preventing infection in this group. | URI: | https://hdl.handle.net/20.500.14279/22925 | ISSN: | 0264410X | DOI: | 10.1016/j.vaccine.2021.07.003 | Rights: | © The Authors.
