Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the […]
Giroir: Americans can expect ‘more normal’ conditions by summer Former Trump White House Coronavirus Task Force member discusses what’s next in pandemic on ‘The Story’ Americans will likely see life begin to return to normal this summer as coronavirus cases, hospitalizations and deaths continue to decline, former Assistant Secretary for Health Brett Giroir told “The […]
Health officials around the world are racing to vaccinate enough people to stop the spread of COVID-19, but what qualifies as “enough” is still an open question. The goal is to get to “herd immunity,” which is when enough people have immunity, either from vaccination or a past infection, to stop uncontrolled spread. Herd immunity […]
People who have recovered from the novel coronavirus infection have immune memory to protect against reinfection for at least eight months, according to a new study which provides strong evidence for the likelihood that Covid-19 vaccines will work for long periods. While earlier studies have shown that antibodies against the coronavirus wane after the first […]
The idea of using herd immunity to manage the COVID-19 pandemic — by allowing low-risk people to acquire the infection naturally as they resume their normal lives — is a “dangerous” and “flawed” approach, according to a new letter signed by 80 international researchers. The letter, published Wednesday (Oct. 14) in the journal The Lancet, […]
Corona-infection: do Not automatically immune? According to the Federal centre for health education (BZgA), studies have shown that people develop after arrested by the SARS-CoV-2-infection-specific antibodies. “It is unclear, however, how robust and durable this immune status is established, and whether there may be human-to-human differences,” wrote the BZgA, a few weeks ago. Meanwhile, there […]
Concerns were raised after South Korean health authorities reported more than 300 people who had already beaten the disease tested positive again. Covid-19 patients who recovered but later test positive for the virus are still secreting dead lung cells, not contracting the infection again, WHO told AFP. If patients who have tackled the disease could possibly […]
Italy began conducting antibody tests in the northern region of Lombardy on Thursday, seeking information about coronavirus immunity to help guide authorities as they reopen the long locked-down country. Lombardy, the region hardest-hit by the coronavirus crisis in Europe’s worst-affected country, is betting that the science about “herd immunity” derived from the blood tests will […]
(HealthDay)—Once you’ve had COVID-19 and recovered, are you now immune from the virus? That’s the critical question that will help shape how the United States re-opens for business in the coming months. Unfortunately, there’s still no clear answer. It’s still too soon to tell if the first wave of COVID-19 survivors will remain immune to […]
