Vaccine nationalism will not shorten COVID pandemic, warns WHO chief https://ift.tt/3oqykEN

The World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus has called for solidarity in the rollout of future coronavirus vaccines. In a video address at the opening of the three-day World Health Summit in Berlin, Tedros Adhanom Ghebreyesus noted that it was natural for the countries to want to protect their own citizens first but, he urged, "we must also use it effectively".

A Black doctor who died battling COVID-19 complained of racist medical care in widely shared social media posts days before her death, prompting an Indiana hospital system to promise a “full external review" into her treatment.

New top story from Time: Pfizer-BioNTech’s COVID-19 Vaccine Works for Teens, According to a New Study

https://ift.tt/39vkf3g Pfizer-BioNTech says their COVID-19 vaccine is 100% efficacious in protecting adolescents aged 12 to 15 years from COVID-19 disease. On March 31, the companies released a statement summarizing the results of their study of the safety and efficacy of their vaccine, which is already authorized in the U.S. and elsewhere for use in adults 16 years or older, in this younger age group. The results have been highly anticipated as state and local leaders—not to mention parents—are to keen send teens back to in-person school; this study suggests a path towards a return to pre-pandemic learning conditions, in which students won’t spread COVID-19 in the classroom. The trial involved 2,260 adolescents 12 to 15 years old, who were randomly assigned to get two doses of the COVID-19 vaccine or two doses of placebo. During the study, which began earlier this year, 18 teens developed COVID-19, all of them in the placebo group. The researchers found that the levels ...

New top story from Time: Pfizer-BioNTech Have Started Testing Their COVID-19 Vaccine in Children Under 12

https://ift.tt/3vWOQjL Alejandra and Marisol Gerardo are nine years old but already making a little bit of history. The twin sisters are among the first young children to get vaccinated with a COVID-19 shot in Pfizer-BioNTech’s study of its vaccine in kids under age 12. Alejandra and Marisol had their blood drawn in the morning on March 24, then got their first dose of the two-dose vaccine later that afternoon. “Their primary concern was, ‘is it going to hurt,’” says their father, Dr. Charles Gerardo, chief of emergency medicine at Duke University School of Medicine. “They’re not too worried about the long term side effects; they’re looking at the moment, not the future.” Testing the vaccine in younger children will answer critical questions about how much immunity the shots can provide, and potentially give parents and education officials more confidence in re-opening schools. While it appears that younger children don’t get as sick with COVID-19 as older teens and adult...

New top story from Time: I Found a Rainbow At the End of My Hunt For a Vaccine Appointment

https://ift.tt/3dt1i2v A version of this article also appeared in the It’s Not Just You newsletter. Sign up here to receive a new edition every Sunday. CHASING RAINBOWS (AND VACCINES) We humans are notoriously unreliable, superstitious narrators, always scanning the horizon for signs that validate what our hearts have already told us. Take me, for example. I keep telling people I was vaccinated at Hogwarts’ Manhattan campus under the waxing moon (it was a gibbous moon to be exact). How auspicious! Ok, so my COVID-vax site was really The City College of New York . But stepping through its big old gothic gates to receive a blessing of science was wondrous, maybe a little spiritual. There was even a rainbow-y halo around that big moon, another lucky omen if you’re hungry for such things. I started digging for lore on moons and rainbows and learned that the physics of rainbows doesn’t detract from the mythical place they have in our cultural imaginations. In fact ...

New coronavirus variant identified in UK; London to be put under highest level of restrictions https://ift.tt/3nkjcbp

A new variant of the novel coronavirus has been identified as responsible for 'faster spread' of the infection in the United Kingdom, the UK government said on Monday. This comes amid a very sharp spike in COVID-19 cases in London and its surrounding areas. According to the details, Britain's capital will now be placed under the highest level of coronavirus restrictions from Wednesday. Health Secretary Matt Hancock told MPs in the House of Commons that "swift and decisive action" was needed as the doubling rate of the deadly virus has hit just seven days in many of these areas.

New top story from Time: The Heartbreak and Horror of Being an EMT During the Pandemic—and Why I’m Still Working

https://ift.tt/3cC9fTO When COVID-19 erupted in New York City last spring , it forced me to make a decision as to whether or not I would work the disaster as an emergency medical technician. Unlike the thousands of New York City EMTs and paramedics who ride on ambulances for the city, private transport companies and hospitals, as a volunteer EMT I rode for free, so I had a choice about what part I would play in the pandemic. When calls for “sick-fever-cough” patients started to infiltrate the city’s 911 system last March, every first responder I know was terrified. I was, too. One night my EMT partner and I sat in my car after a tour and had a long existential conversation. Was volunteering to work as EMTs during a lethal contagion the stupidest thing we could do? Or was it the most self-sacrificing? In the end I decided to ride. I was far from the only rescuer who wanted to be of service when crisis struck. An army of almost 90,000 health care workers volunteered to ste...

New top story from Time: ‘Garbage Freaking Everywhere’ as Americans Venture Outdoors After a Year of Lockdowns

https://ift.tt/31mr3M8 Across the country, as the weather improved and pandemic lockdowns were lifted, Americans ventured outside and noticed that their neighborhoods looked a little different. A little. . . dirtier. They saw mattresses piled outside cemeteries and disposable masks clogging the gutters. Vacuum cleaners left in the woods, fast food wrappers blowing on the highway, piles of tires. Neighborhoods that had been relatively clean before the pandemic were now full of litter. “There is garbage freaking everywhere,” says David Biderman, the executive director and CEO of the Solid Waste Association of North America (SWANA). In Portland, Ore., the city picked up more garbage in 2020 than any other year on record: 3,000 tons, 50% more than the previous year. Additionally, requests to clean up trash and remove graffiti were up 300% over 2019. Norfolk, Va., is seeing “historic highs” in litter and illegal dumping, according to Sarah Sterzing, the program manager of Ke...

New top story from Time: The World’s First Malaria Vaccine—and What it Means for the Future of Pandemic Response

https://ift.tt/3uQFdD3 On Oct. 6, the World Health Organization recommended use of the first vaccine to fight malaria . The decision is momentous and highly anticipated for many reasons: among them is that this is the first vaccine to help reduce the risk of deadly severe malaria in young children in Sub-Saharan Africa, where the disease remains a leading killer. The vaccine offers hope that there can be a circle of learning from one pandemic to the next. Malaria, our oldest pandemic, may offer insights on how we can survive contemporary scourges like COVID-19. Malaria evolved at least 2.5 million years ago and first infected humans in rural parts of Africa. It then spread to all continents save Antarctica—notably, killing off armies ranging from those trying to conquer ancient Rome to those battling to control the Pacific in World War II. Malaria, according to historians, may have killed more people than any other pandemic. [time-brightcove not-tgx=”true”] Malaria changed ...
