Lower probability and shorter duration of infections after COVID-19 vaccine correlate with anti-SARS-CoV-2 circulating IgGs.

The correlation between immune responses and protection from SARS-CoV-2 infections and its duration remains unclear. We performed a sanitary surveillance at the European Institute of Oncology (IEO) in Milan over a 17 months period. Pre-vaccination, in 1,493 participants, we scored 266 infections (17.8%) and 8 possible reinfections (3%). Post-vaccination, we identified 30 infections in 2,029 vaccinated individuals (1.5%). We report that the probability of infection post-vaccination is i) significantly lower compared to natural infection, ii) associated with a significantly shorter median duration of infection than that of first infection and reinfection, iii) anticorrelated with circulating antibody levels.

COVID-19 and radiotherapy: impact on work and personal life of Lombardy residents during first lockdown, survey endorsed by AIRO Young.

AIM: Since 20 February 2020, Lombardy has been one of the most affected areas worldwide by the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study is to evaluate work and psychological impact of COVID-19 on Lombardy radiation therapy (RT) residents in the first 3 months of the outbreak (first lockdown). METHODS: An online questionnaire (22 multiple choice questions) via Microsoft Forms was administered on 30 May 2020 to RT residents. RESULTS: Nineteen Lombardy RT residents responded to the survey. Nineteen percent of residents underwent a nasal swab and 11% were quarantined. Seventeen residents (89%) reported an increase in workload. Twelve residents (63%) did not find any difference in terms of work distress; worsening was highlighted in 5 cases (26%). The majority has never considered the possibility of stopping work due to excessive stress (89%). Almost all the residents experienced self- or relative-referred apprehension (95%). Ninety-five percent reported having missed extra-work social relationships. Most of the sample noted worsening sleep quality and difficulty concentrating (69%). No residents requested psychological support, even if provided by the hospital. CONCLUSION: Overall, the residents adapted to the new workplace scenario, although some health risks and well-being challenges have been reported. An extension of the survey to all Italian RT residents endorsed by Italian Association of Radiotherapy and Clinical Oncology "Young AIRO" will allow an evaluation of COVID-19 impact on a national level. A second survey is planned to underline differences between the first lockdown and the current situation of the pandemic.
