Safety after the second dose of the SARS-CoV-2 vaccine remains to be elucidated, especially among individuals reporting adverse events after their first dose. This study aims to evaluate the impact of a delayed second dose on all-cause mortality and emergency services. ⋯ No significant association between delayed second dose of BNT162b2 or CoronaVac and all-cause mortality, ED visit, and unscheduled hospitalization was observed in the present cohort. Regardless of the recommended or delayed schedule for SARS-CoV-2 vaccination, a second dose of both vaccines should be administered to obtain better protection against infection and serious disease. The second dose should be administered within the recommended interval following the manufacturer's product information, until further studies support the benefits of delaying vaccination outweighing the risks.

Background and Objectives: The safety and effectiveness of vaccines are among the key priorities in COVID-19 pandemic management. Moreover, evidence-based data regarding vaccine safety and immunogenicity can play an important role in building the trust of the community regarding vaccination. The aim of this study was to investigate the safety and immunogenicity of Pfizer-BioNTech vaccine among healthcare workers in one hospital, 21 days after first dose. ⋯ Younger participants experienced adverse events and were positive for IgG antibodies more frequently than older counterparts. It is important to mention that this study specifically considered short-term safety and reactions following vaccination and that long-term adverse effects were not investigated in the study. Thus, future research into both long-term adverse reactions and immune system programming is essential.

Opioids are part of the daily routine in anesthesiology and palliative care; however, treatment of dyspnea with opioids is presented heterogeneously in guidelines. This may result in an uncertainty concerning opioid indications and ethical concerns, especially when caring for COVID-19 patients. ⋯ Anesthesiologists perceived considerable uncertainty in using M/O for nonpalliative care medical settings. Highest uncertainty was seen for the care of patients with COVID-19. The prevalent use of the subcutaneous route for M/O application in palliative care can serve as inspiration for areas outside palliative care as well. Uniform interdisciplinary guidelines for symptom control including dyspnea, education and involvement of a palliative care consultation team should be more considered in the future.

Observational Study
Result Turnaround Time of RT-PCR for SARS-CoV-2 is the Main Cause of COVID-19 Diagnostic Delay: A Country-Wide Observational Study of Mexico and Colombia.
Delay in COVID-19 diagnosis due to late real-time reverse transcription-polymerase chain reaction reporting has been described to be an important cause of suboptimal COVID-19 surveillance and outbreak containment. ⋯ Diagnostic delay was mostly due to test turnaround time. Marginalization status was an important barrier to diagnostic test access.
