A world-wide immunization project was launched at the peak of COVID-19 pandemic to contain and minimize the adverse effects of SARS-CoV-2 virus. We carried out a series of statistical analyses in this paper to determine, confirm and quantify the impact of the vaccinations on COVID-19 cases and mortalities, amidst critical confounding factors-temperature and solar irradiance. ⋯ Results show that the world-wide vaccination against COVID-19 project had a significant impact in reducing mortalities and minimizing the adverse effects due to COVID-19 globally, in all five (5) major continents of the world and the countries studied in this work, however, temperature and solar irradiance still had effects on COVID-19 response in the vaccination eras.

Growing evidence suggests an important contribution of airborne transmission to the overall spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), in particular via smaller particles called aerosols. However, the contribution of school children to SARS-CoV-2 transmission remains uncertain. The aim of this study was to assess transmission of airborne respiratory infections and the association with infection control measures in schools using a multiple-measurement approach. ⋯ Molecular detection of airborne and human SARS-CoV-2 indicated sustained transmission in schools. Mask mandates were associated with greater reductions in aerosol concentrations than air cleaners and with lower transmission. Our multiple-measurement approach could be used to continuously monitor transmission risk of respiratory infections and the effectiveness of infection control measures in schools and other congregate settings.

ReviewUnderstanding advance care planning in care homes throughout the COVID-19 pandemic: A critical realist review and synthesis.
The COVID-19 pandemic has disrupted advance care planning discussions in care homes, particularly discussions involving relatives and surrogate decision makers. There is a need to collate and examine current evidence to assess the extent of the problem. ⋯ Results highlight part of the new context facing staff, relatives and residents in care homes, thus providing valuable insight for future intervention development required to maintain and improve the effectiveness of advance care planning in care homes during and beyond the pandemic.
