The United States is devoting $3.2 billion to speed development of antiviral pills to treat COVID-19 and other dangerous viruses that could turn into pandemics. The new program will invest in “accelerating things that are already in progress” for COVID-19 but also would work to come up with treatments for other viruses, said Dr. Anthony Fauci, the nation’s top infectious disease expert. He announced the investment at a White House briefing. “There are few treatments that exist for many of the viruses that have pandemic potential,” he said, including Ebola, dengue, West Nile and Middle East respiratory syndrome. But he added, “vaccines clearly remain the centerpiece of our arsenal. The U.S. has approved one antiviral drug, remdesivir, specifically for COVID-19, and allowed emerg...

The internet seems to know exactly which vaccines are the best - and the worst. But you can't compare vaccines that easily. And doing so might even be harmful in a pandemic. We tend to look at efficacy rates. Because they measure how likely you are to get COVID-19 after you’ve been vaccinated. The problem is that these numbers were not created equal. Instead they are determined by when and where the efficacy trials took place and who was included. Watch here: https://www.youtube.com/watch?v=BRKZh_RXJC0 Source: DW

Many people who have been infected with SARS-CoV-2 will probably make antibodies against the virus for most of their lives. So suggest researchers who have identified long-lived antibody-producing cells in the bone marrow of people who have recovered from COVID-19. The study provides evidence that immunity triggered by SARS-CoV-2 infection will be extraordinarily long-lasting. Adding to the good news, “the implications are that vaccines will have the same durable effect”, says Menno van Zelm, an immunologist at Monash University in Melbourne, Australia. Antibodies — proteins that can recognize and help to inactivate viral particles — are a key immune defence. After a new infection, short-lived cells called plasmablasts are an early source of antibodies. But these cells recede soon...

The Centers for Disease Control and Prevention is looking into reports that a very small number of teenagers and young adults vaccinated against the coronavirus may have experienced heart problems, according to the agency’s vaccine safety group. The group’s statement was sparse in details, saying only that there were “relatively few” cases and that they may be entirely unrelated to vaccination. The condition, called myocarditis, is an inflammation of the heart muscle, and can occur following certain infections. The C.D.C.’s review of the reports is in the early stages, and the agency has yet to determine whether there is any evidence that the vaccines caused the heart condition. The agency has posted guidance on its website urging doctors and clinicians to be alert to unusual he...

GHealth News - WHO listed the Sinopharm COVID-19 vaccine for emergency use, giving the green light for this vaccine to be rolled out globally. The Sinopharm vaccine is produced by Beijing Bio-Institute of Biological Products Co Ltd, subsidiary of China National Biotec Group (CNBG).  “The addition of this vaccine has the potential to rapidly accelerate COVID-19 vaccine access for countries seeking to protect health workers and populations at risk,” said Dr Mariângela Simão, WHO Assistant-Director General for Access to Health Products. “We urge the manufacturer to participate in the COVAX Facility and contribute to the goal of more equitable vaccine distribution.” WHO’s Emergency Use Listing (EUL) is a prerequisite for COVAX Facility vaccine supply. It also allows countries to expedite...

By Laurie McGinley and Lenny Bernstein The announcement by the Centers for Disease Control and Prevention on Thursday that people who have been fully vaccinated against the coronavirus no longer need to wear masks in most places was hailed as the path to liberation for many who have endured through the strictures of the pandemic. But the new recommendations also raised an array of questions and complications for businesses, consumers and parents — and the answers might not be clear for some time. Does the new CDC recommendation mean that if I am vaccinated I no longer have to wear a mask anywhere? No. The CDC wants vaccinated people to wear masks in health-care settings and on planes, buses, trains and other public transportation. Also, everyone will have to abide b...

By Vikas Pandey - On Monday, a senior official from India's federal government told journalists that there was no shortage of oxygen in Delhi or anywhere else in the country. As he spoke, several small hospitals - only a few miles from where he stood in the capital - were sending out desperate messages about them running out of oxygen, putting patients' lives at risk. The chief doctor of one of the hospitals - a specialist paediatric facility - told the BBC that "our hearts were in our mouths" because of the risk of children dying. They got supplies just in time, after a local politician intervened. And yet, the federal government has repeatedly insisted that there was no shortage. "We are only facing problems in its transportation," Piyush Goyal, a senior official from India's ho...

CNBC- Pfizer’s experimental oral drug to treat COVID-19 at the first sign of illness could be available by the end of the year, CEO Albert Bourla told CNBC. The company, which developed the first authorized COVID-19 vaccine in the U.S. with German drugmaker BioNTech, began in March an early stage clinical trial testing a new antiviral therapy for the disease. The drug is part of a class of medicines called protease inhibitors and works by inhibiting an enzyme that the virus needs to replicate in human cells. Protease inhibitors are used to treat other viral pathogens such as HIV and hepatitis C. If clinical trials go well and the Food and Drug Administration approves it, the drug could be distributed across the U.S. by the end of the year, Bourla told CNBC’s “Squawk...

by Michael Safi They will be remembered as India’s lost months: the stretch between September and February when Covid-19 cases in the country defied global trends, falling sharply throughout the coldest months of the year until they reached four-figure daily totals. It was inexplicable. Was it the Indian climate? A protection conferred by childhood immunisations? Some speculated India may have naturally reached herd immunity. It was a tantalising idea that took hold in India’s highest circles of policymaking, media and science – even a government-commissioned study suggested herd immunity may indeed have been achieved. It would prove one of the most fatal miscalculations of the Covid-19 pandemic so far. Now, with daily cases crossing 360,000, and recorded deaths beyond 3,200 per ...

By Sandee LaMotte Have you recently had the single-shot Johnson & Johnson Covid-19 vaccine? Get medical attention quickly if you suffer persistent, severe headaches, blurred vision, shortness of breath, chest pain, leg swelling, persistent abdominal pain or unusual bruising within three weeks of getting the J&J vaccine, the US Centers for Disease Prevention and Control said Monday in a new posting on its website. Those could be signs of an extremely rare, severe blood clotting syndrome that may be linked to the Johnson & Johnson vaccine. The risk appears greatest for women under the age of 50, the CDC said. "This adverse event is rare, occurring at a rate of about 7 per 1 million vaccinated women between 18 and 49 years old," the CDC wrote. "For women 50 y...
