An upper bound on one-to-one exposure to infectious human respiratory particles.
Proceedings of the National Academy of Sciences of the Un... Bagheri G, Thiede B et. al.

Dec 4th, 2021 - There is ample evidence that masking and social distancing are effective in reducing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. However, due to the complexity of airborne disease transmission, it is difficult to quantify their effectiveness, especially in the case of one-to-one exposure. Here, we introduce the concept of an upper bound for one-to-one exposure to ...

American Journal of Transplantation : Official Journal Of... Reischig T, Kacer M et. al.

Dec 4th, 2021 - Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccination may fail to sufficiently protect transplant recipients against coronavirus disease 2019 (COVID-19). We retrospectively evaluated COVID-19 in kidney transplant recipients (n=226) after BNT162b2 mRNA vaccine administration. The control group consisted of unvaccinated patients (n=194) during the previous pandemic wave. W...
