According to the companies, the trial will evaluate the safety, tolerability, and immune response of the vaccine that can be administered as a primary shot and a booster.

Canadian researchers have found that rapid antigen tests to detect the SARS-CoV-2 virus are associated with a very low rate of false positive results.

As the omicron variant continues to surge across the country, putting staff at many practices on edge, waning immunity may be driving an increase in virus infections.

Informed guidelines are needed to diagnose and treat COVID-19 patients with neurologic manifestations, according to investigators.

The investigators believe that, based on their findings, the impact of COVID-19 on the autonomous nervous system warrants further prospective studies and assessment of pupillary function might be a useful test for determining autonomic dysfunction.

Investigators say study validates the importance of history-based donor screening while also demonstrating that postmortem PCR testing as a criterion for procurement and subsequent use of tissue isn’t necessary.

Delayed presentations and acute shortage of donor corneal tissues for emergency keratoplasty are among reasons given for adverse outcome.

Investigators have cited the need for pharmacologic and non-pharmacologic interventions to improve the ongoing burden after hospitalization for COVID-19.
