Covid-19 Vaccines Yield Breakthroughs in Long-Term Fight Against Infectious Disease
Â
The pandemic has opened a new era for vaccines developed with gene-based technologies, techniques that have long stumped scientists and pharmaceutical companies, suggesting the possibility of future protection against a range of infectious disease.
Johnson & Johnsonâs Covid-19 vaccine, which was authorized Saturday for use in the U.S., is at the vanguard of a class of shots designed to mobilize a personâs immune defenses against the disease. It will be the first Covid-19 vaccine administered in the U.S. that uses viral-vector technology, which employs an engineered cold virus to ferry coronavirus-fighting genetic code to the bodyâs cells.

Home delivery of HIV medicines in South Africa significantly increased viral suppression compared to those who received clinical care, a study conducted by researchers at the University of Washington School of Medicine.
The study, conducted with Amazon.com guidance during COVID-19 restrictions in South Africa, showed that among study participants, paying a fee for home delivery and monitoring of antiretroviral therapy (ART) was highly acceptable in the context of low income and high unemployment, and improved health outcomes as a result.
The researching findings were presented March 8 at Virtual CROI 2021.
Up to this point, vaccine-related ethical questions have mostly been about taking them: Should you accept a shot thatâs about to be thrown away? Does increasing herd immunity justify jumping the line? Now the focus is turning to giving. Will affluent countries contribute to the greater good by releasing their hold on so much of the worldâs vaccine supply? If they donât, that could extend the pandemicâand depress global trade, keep borders closed, and provide variants the opportunity to evolve.
âThis is a question of global justice, fairness, and morality,â says Gavin Yamey, a physician and director of Duke Universityâs Center for Policy Impact in Global Health. âThere is a very powerful ethical reason why people everywhere should have the right to vaccines as a global public good, and that vaccines should not just be hoarded by rich nations. I know that that argument alone may not be persuasive to rich people in rich countries, but it is one t
Scientists at the University of Washington have developed a new artificial intelligence system that allows smart speakers, like the Amazon Echo and Google Home, to locate and measure both regular and irregular heartbeats

As it turns out, smart speakers have proven to be handy in hospitals, allowing patients to independently control devices, as well as lessen the workload for clinicians and caretakers. And now, researchers from the University of Washington have developed an artificial intelligence system that enables these devices to monitor regular and irregular heartbeats.
