Study: Most with severe COVID-19 develop a ‘robust’ antibody response

Study: Most with severe COVID-19 develop a ‘robust’ antibody response

Health
Feb. 11 (UPI) -- Most people's immune systems can fight back against COVID-19 when they develop severe disease, according to a study published Thursday by PLOS Pathogens. Eight people, after recovery from serious illness, had higher levels of neutralizing antibodies against the virus than 10 patients with more mild symptoms, the data showed. Advertisement Neutralizing antibodies are proteins produced by the immune system to fight off infections. The findings support the use of antibody-based therapy, perhaps with blood plasma donated by those who have recovered from COVID-19, to prevent and treat the disease, the researchers said. "Even with a vaccine at our doorstep, arming clinicians with specific anti-[COVID-19] therapeutics is extremely important," wrote the authors, from Tel Aviv Un...

Dec. 28 (UPI) -- Japan clamped down on international visits by non-resident foreign nationals until the end of January in response to the spread of a new more virulent variant of the coronavirus that has sickened people in 20 countries. "They say that no evidence is showing the vaccines that are already being administered overseas are not effective against this variant, and anti-infection steps for it are unchanged from those for the conventional virus," Prime Minister Yoshihide Suga said Monday, urging residents to have a "calm" New Year celebration. "The virus recognizes no year-end or New Year holidays," Suga added.

Oxford vaccine produces strong immune response in older adults, early results show

Technology
The COVID-19 vaccine developed by Oxford University produces a strong immune response in older adults, data from early trials has shown.The phase one and phase two results suggest that one of the groups most at risk of death or serious illness from COVID-19 may be able to build immunity, according to data published in The Lancet medical journal. It comes a day after Pfizer announced its coronavirus vaccine was 94% effective among adults over 65 in its final efficacy results, and that it would be seeking authorisation over the next few days.Live coronavirus updates from the UK and around the world Please use Chrome browser for a more accessible video player ...
Fauci sees similarities between HIV, COVID-19 in public health response

Fauci sees similarities between HIV, COVID-19 in public health response

Health
Oct. 16 (UPI) -- The HIV epidemic in the 1980s and the ongoing COVID-19 pandemic are very different but the two share "some similarities" related to public health response, Dr. Anthony Fauci said Friday. Fauci, director of the National Institute of Allergy and Infectious Diseases, was a researcher at the government agency during the early stages of the HIV/AIDS epidemic, and he recalls the "messaging difficulty" he and his colleagues faced then. Advertisement At least initially, a widely held belief existed that HIV/AIDS affected only "one community" and "would not become a global problem," as it eventually did, Fauci said during a "fireside chat" hosted by Johns Hopkins University's Bloomberg School of Public Health. Because some people infected with the new coronavirus only experience m...
