Scientists Estimate 73% of US Population May Be Immune to SARS-CoV-2 Omicron Variant

Clinical laboratory scientists should also know experts warn that ‘herd resistance’ is more likely than ‘herd immunity’ due to low vaccination rates in many parts of the world Scientists estimate 73% of the US population may be immune to the SARS-CoV-2 omicron variant. Whether the nation is approaching “herd immunity” against the disease, however, remains open to debate, the Associated Press (AP) reported. These estimates are relevant to medical laboratories doing serology tests for COVID-19,...

Scientists Identify Growing Number of COVID-19 Variants, But Not All Clinical Laboratories Have the Capability to Test for Variants

Fear that immunity-resistant mutations of SARS-CoV-2 will emerge are real and the scientific community is paying close attention Detection of an increasing number of new variants of the SARS-CoV-2 coronavirus raises the possibility that a new strain of COVID-19 might emerge that brings new problems to the management of the pandemic. Public health officials and clinical laboratory scientists are on the alert to determine if any new COVID-19 variant is more virulent or more easily transmissible....

Immunocompromised Patients with COVID-19 May Remain Infectious for Much Longer than Previously Thought

Clinical laboratory professionals should note that one case study describes a COVID-positive cancer patient shedding infectious particles for five months, which is much longer than expected Just when researchers start believing they understand COVID-19 infections, something happens that reveals there is still more to learn. These additional findings are relevant for clinical laboratory managers and pathologists because the new insights often may play a role in how SARS-CoV-2 results should be...

Where Did all the Antibodies Go? Emory University’s Vaccine Center Studies Bone Marrow to Find Out Why Influenza Vaccines are Short-Lived

Pathologists and clinical laboratory scientists know that influenza vaccines typically produce short-lived protection and researchers have new clues as to why this is true With so much interest in development of a COVID-19 vaccine, findings by researchers at Atlanta’s Emory Vaccine Center into why the vaccine for influenza (Flu) is so short-lived offer a new window on how the body’s immune system responds to invading viruses and what happens to the immunity over time. Because the autumn...

February COVID-19 Superspreader Event in Boston Confirmed by Use of Genetic Sequencing as Next-Gen Sequencing Is Put to Novel Uses, including in Clinical Laboratories

Gene sequencing is enabling disease tracking in new ways that include retesting laboratory specimens from before the SARS-CoV-2 outbreak to determine when it arrived in the US On February 26 of this year, nearly 200 executives and employees of neuroscience-biotechnology company Biogen gathered at the Boston Marriott Long Wharf hotel for their annual leadership conference. Unbeknownst to the attendees, by the end of the following day, dozens of them had been exposed to and become infected by...
