1. Type O and Rh negative blood groups associated with slightly lower risk for SARS-CoV-2 infection
A person's blood type may affect their risk for SARS-CoV-2 infection and for developing severe COVID-19-related illness. A population-based retrospective cohort study is published in Annals of Internal Medicine.
Researchers from ICES in Toronto studied 225,556 persons who had an ABO blood group test from January 2007 to December 2019, and had a SARS-CoV-2 lab test subsequently to determine whether ABO and Rh blood groups are associated with risk for SARS-CoV-2 infection and severe COVID-19 illness. The population-based study was conducted in Ontario Canada, which has universal health care and widespread SARS-CoV-2 testing. The authors found that O and Rh? blood groups were associated with a slightly lower risk for SARSCoV-2 infection as well as severe COVID-19 illness or death. The authors wonder whether similar differences will be seen within ongoing clinical trials studying the therapeutic efficacy of SARS-CoV-2 immunotherapy or vaccination.

2. If licensed soon, a SARS-CoV-2 vaccine would be an unprecedented achievement
The development of a safe and effective vaccine for SARS-CoV-2 is a crucial global health goal, but anticipated success rates and timelines for COVID-19 vaccine development vary.
Researchers from McGill University reviewed trials testing viral vaccines that had not advanced to phase 2 between January 2005 and March 2020 on ClinicalTrials.gov, and tracked the progress of each vaccine from phase 1 through to FDA licensure to estimate timelines and probabilities of success for recent vaccine candidates. Ultimately, they found success probabilities and timelines varied widely across different vaccine types and diseases. If a SARS-CoV-2 vaccine is licensed within 18 months of the start of the pandemic, it will mark an unprecedented achievement for noninfluenza viral vaccine development. The findings are published in Annals of Internal Medicine.

3. Surviving COVID-19 patients may benefit from home health care after hospital discharge
Survivors of COVID-19 are a vulnerable population and may require further hospitalization, but little is known about recovery after hospital discharge. Authors from the University of Pennsylvania Schools of Nursing and Medicine, Villanova University Fitzpatrick College of Nursing, and the Visiting Nurse Service of New York describe the home health recovery of patients with COVID-19 and risk factors associated with rehospitalization or death.
The researchers studied 1,409 patients with COVID-19 admitted to home health care (HHC) after hospitalization. After an average of 32 days in HHC, 94 percent of patients were discharged and most achieved statistically significant improvements in symptoms and function. These findings suggest that acute care providers might carefully consider which COVID-19 survivors would benefit from HHC after hospitalization. They call for further research to determine longer-term outcomes of CO VID-19 and to target extra attention to patients with risk factors. The findings are published in Annals of Internal Medicine.
