Chilean scientists have announced the discovery of the first-ever southern hemisphere remains of a type of Jurassic-era “winged lizard” known as a pterosaur.Fossils of the dinosaur which lived some 160 million years ago in what is today the Atacama desert, were unearthed in 2009.They have now been confirmed to be of a rhamphorhynchine pterosaur — the first such creature to be found in Gondwana, the prehistoric supercontinent that later formed the southern hemisphere landmasses.Researcher Jhonatan Alarcon of the University of Chile said the creatures had a wingspan of up to 2 meters, a long tail, and pointed snout.”We show that the distribution of animals in this group was wider than known to date,” he added.The discovery was also “the oldest known pterosaur found in Chile,” the scientists reported in the scientific journal Acta Palaeontologica Polonica.

Several hundred people line up every morning, starting before dawn, on a grassy area outside Nairobi’s largest hospital hoping to get the COVID-19 vaccine. Sometimes the line moves smoothly, while on other days, the staff tells them there’s nothing available and they should come back tomorrow.Halfway around the world, at a church in Atlanta in the U.S. state of Georgia, two workers with plenty of vaccine doses waited hours Wednesday for anyone to show up, whiling away the time by listening to music from a laptop. In six hours, one person came through the door.The dramatic contrast highlights the vast disparity around the world. In richer countries, people can often pick and choose from multiple available vaccines, walk into a site near their homes and get a shot in minutes. Pop-up clinics, such as the one in Atlanta, bring vaccines into rural areas and urban neighborhoods, but it is common for them to get very few takers.In the developing world, supply is limited and uncertain. Just more than 3% of people across Africa have been fully vaccinated, and health officials and citizens often have little idea what will be available from one day to the next. More vaccines have been flowing in recent weeks, but the World Health Organization’s director in Africa said Thursday that the continent will get 25% fewer doses than anticipated by the end of the year, in part because of the rollout of booster shots in wealthier counties such as the United States.Bidian Okoth said he spent more than three hours in line at a Nairobi hospital, only to be told to go home because there weren’t enough doses. But a friend who traveled to the U.S. got a shot almost immediately after his arrival there with a vaccine of his choice, “like candy,” he said.”We’re struggling with what time in the morning we need to wake up to get the first shot. Then you hear people choosing their vaccines. That’s super, super excessive,” he said.Okoth said his uncle died from COVID-19 in June and had given up twice on getting vaccinated because of the length of the lines, even though he was eligible because of his age. The death jolted Okoth, a health advocate, into seeking a dose for himself.He stopped at one hospital so often on his way to work that a doctor “got tired of seeing me” and told Okoth he would call him when doses were available. Late last month, after a new donation of vaccines arrived from Britain, he got his shot.The disparity comes as the U.S. is moving closer to offering booster shots to large segments of the population even as it struggles to persuade Americans to get vaccinated in the first place. President Joe Biden on Thursday ordered sweeping new federal vaccine requirements for as many as 100 million Americans, including private-sector employees, as the country faces the surging COVID-19 delta variant.Riley Erickson poses for a photo at Springfield Missionary Baptist Church in Atlanta on Sept. 8, 2021, where the disaster relief group CORE was offering COVID-19 vaccinations. The one person who showed up was a college student.About 53% of the U.S. population is fully vaccinated, and the country is averaging about 145,000 new cases of COVID-19 a day, along with about 1,600 deaths, according to Johns Hopkins Coronavirus Resource Center. Africa has had more than 7.9 million confirmed cases, including more than 200,000 deaths, and the highly infectious delta variant recently drove a surge in new cases as well.John Nkengasong, director of the Africa Centers for Disease Control and Prevention, told reporters Thursday that “we have not seen enough science” to drive decisions on when to administer booster shots.”Without that, we are gambling,” he said, and urged countries to send doses to countries facing “vaccine famine” instead.In the U.S., vaccines are easy to find, but some people are hesitant to get them.At the church in northwest Atlanta, a nonprofit group offered the Johnson & Johnson and Pfizer vaccines for free without an appointment from 10:30 a.m. to 4:30 p.m. But site manager Riley Erickson spent much of the day waiting in an air-conditioned room full of empty chairs, though the group had reached out to neighbors and the church had advertised the location to its large congregation.Erickson, with the disaster relief organization CORE, said the vaccination rate in the area was low and he wasn’t surprised by the small turnout. The one person who showed up was a college student.FILE – In this Aug. 20, 2021, photo, medical workers prepare to remove the body of a coronavirus victim in the intensive care unit of a hospital in Machakos, Kenya.”When you put the effort into going into areas where there’s less interest, that’s kind of the result,” he said. His takeaway, however, was that CORE needed to spend more time in the community.Margaret Herro, CORE’s Georgia director, said the group has seen an uptick in vaccinations at its pop-up sites in recent weeks amid a COVID-19 surge fueled by the delta variant and the FDA’s full approval of the Pfizer vaccine. It also has gone to meatpacking plants and other work locations, where turnout is better, and it plans to focus more on those places, Herro said.In Nairobi, Okoth believes there should be a global commitment to equity in the administration of vaccines so everyone has a basic level of immunity as quickly as possible.”If everyone at least gets a first shot, I don’t think anyone will care if others get even six booster shots,” he said.

At a taxi stand by a bustling market in Kampala, Uganda’s capital, traders simply cross a road or two, get a shot in the arm and rush back to their work.Until this week, vaccination centers were based mostly in hospitals in this East African country that faced a brutal COVID-19 surge earlier this year.Now, more than a dozen tented sites have been set up in busy areas to make it easier to get inoculated in Kampala as health authorities team up with the Red Cross to administer more than 120,000 doses that will expire at the end of September.“All of this we could have done earlier, but we were not assured of availability of vaccines,” said Dr. Misaki Wayengera, who leads a team of scientists advising authorities on the pandemic response, speaking of vaccination spots in downtown areas. “Right now, we are receiving more vaccines and we have to deploy them as much as possible.”In addition to the 128,000 AstraZeneca doses donated by Norway at the end of August, the United Kingdom last month donated nearly 300,000 doses. China recently donated 300,000 doses of its Sinovac vaccine, and on Monday a batch of 647,000 Moderna doses donated by the United States arrived in Uganda.Suddenly Uganda must accelerate its vaccination drive. The country has sometimes struggled with hesitancy as some question the safety of the two-shot AstraZeneca vaccine, which is no longer in use in Norway because of concerns over unusual blood clots in a small number of people who received it.Africa has fully vaccinated just 3.1% of its 1.3 billion people, according to the Africa Centers for Disease Control and Prevention. Public health officials across Africa have complained loudly of vaccine inequality and what they see as hoarding in some rich countries. Soon hundreds of millions of vaccine doses will be delivered to Africa through donations of excess doses by wealthy nations or purchases by the African Union.Africa is aiming to vaccinate 60% of the continent’s population by the end of 2022, a steep target given the global demand for doses. The African Union, representing the continent’s 54 countries, has ordered 400 million Johnson & Johnson doses, but the distribution of those doses will be spread out over 12 months because there simply isn’t enough supply.A nurse administers a coronavirus vaccination at Kisenyi Health Center in downtown Kampala, Uganda, Sept. 8, 2021.COVAX, the U.N.-backed program which aims to get vaccines to the neediest people in the world, said this week that its efforts continue “to be hampered by export bans, the prioritization of bilateral deals by manufacturers and countries, ongoing challenges in scaling up production by some key producers, and delays in filing for regulatory approval.”Uganda, a country of more than 44 million people, has recorded more than 120,000 cases of COVID-19, including just over 3,000 deaths, according to official figures. The country has given 1.65 million shots, but only about 400,000 people have received two doses, according to Wayengera. Uganda’s target is to fully vaccinate up to 5 million of the most vulnerable, including nurses and teachers, as soon as possible.At the Red Cross tent in downtown Kampala, demand for the jabs was high. By late afternoon only 30 of 150 doses remained, and some who arrived later were told to come back the next day.“I came here on a sure deal, but it hasn’t happened,” said trader Sulaiman Mivule after a nurse told him he was too late for a shot that day. “I will come back tomorrow. It’s easy for me here because I work in this area.”Asked why he was so eager to get his first shot, he said, “They are telling us that there could be a third wave. If it comes when we are very vaccinated, maybe it will not hurt us so much. Prevention is better than cure.”Mivule and others who spoke to the AP said they didn’t want to go to vaccination sites at hospitals because of they expected to find crowds there.Bernard Ssembatya said he had been driving by when he spotted the Red Cross’s white tent and went in for a jab on the spur of the moment. Afterward, he texted his friends about the opportunity.“I was getting demoralized by going to health centers,” he said. “You see a lot of people there and you don’t even want to try to enter.”Yet, despite enthusiasm among many, some still walked away without getting a shot when they were told their preferred vaccine was not yet available.The one-shot J&J vaccine, still unavailable in Uganda, is frequently asked for, said Jacinta Twinomujuni, a nurse with the Kampala Capital City Authority who monitored the scene.“I tell them, of course, that we don’t have it,” she said. “And they say, ‘OK, let’s wait for it.’”

New U.S. studies released Friday show that COVID-19 vaccines provide strong protection against hospitalizations and death, even in cases involving the highly contagious delta variant.One study, which followed 600,000 people from April through mid-July, found that people who were not vaccinated were more than 10 times more likely to be hospitalized and 11 times more likely to die than those who were fully vaccinated.The unvaccinated were 4.5 times more likely to get infected, according to the study released Friday by the U.S. Centers for Disease Control and Prevention.The CDC also released two other studies that show vaccine protection appearing to wane in older populations, particularly those 75 and older.The studies also show an increase in milder COVID-19 infections among fully vaccinated people.Dr. Rochelle Walensky, the CDC director, said during a White House COVID-19 briefing Friday that the data showed “vaccination works and will protect us from the severe complications of COVID-19.”The release of the studies comes a day after U.S. President Joe Biden announced a new vaccine mandate requiring big companies to ensure their workers are vaccinated. The order could affect as many as 100 million Americans.Republican officials in several states joined Republican calls to fight the new mandate in court.Mississippi’s Governor Tate Reeves, a Republican, said Friday that Biden’s federal vaccine requirements were “clearly unconstitutional” and that Mississippi would join other states in filing a lawsuit.Montana’s attorney general, Austin Knudsen, also promised Friday to fight the new federal vaccine mandate in court as soon as the full guidelines are released.In other developments Friday, Denmark lifted the last of its COVID-19 restrictions. Vaccine passports are no longer required to enter nightclubs; the rule was removed for other venues Sept. 1.On Saturday, Denmark will celebrate its new status with a sold-out concert for 50,000 people.The Scandanavian country’s vaccine rollout has gone well, with 73% of its 5.8 million population fully vaccinated, including 96% of those 65 and older.In France, former French Health Minister Agnes Buzyn was charged Friday over her handling of the COVID-19 pandemic, according to the Agence France-Presse.Buzyn was charged with “endangering the lives of others.”French officials Friday also unveiled new restrictions for U.S. travelers not vaccinated against the coronavirus. Those travelers now must show “pressing grounds for travel” in addition to the previous requirement of a negative COVID-19 test.In South Africa, health officials began vaccinating children, taking part in clinical trials of China’s Sinovac Biotech inoculation for children 6 months to 17 years.The Johns Hopkins Coronavirus Resource Center said late Friday that it had recorded 223.6 million global COVID-19 cases and 4.6 million deaths. The center said 5.6 billion vaccine doses have been administered.Some information for this report came from The Associated Press, Reuters, and Agence France-Presse.

Just over two months ago, on Independence Day, President Joe Biden declared that the United States was “closer than ever to declaring our independence from a deadly virus.” Vaccines had driven down the average daily death toll from COVID-19 from more than 3,400 at the start of the year to around 400 in early July.  It didn’t last.  On Thursday, with about 1,500 Americans dying of COVID-19 each day, according to ourworldindata.org, Biden announced new measures aimed at beating back the virus again.  Public health experts applaud the stepped-up efforts, including new vaccine mandates and increased access to testing. But some say they do not go far enough. And they note that the Biden administration’s mixed messaging deserves some of the blame for the current situation.  ‘Pandemic of the unvaccinated’ Despite vaccines that are safe, effective, free and widely available, one-quarter of the adult population has not yet taken its first shot.  The highly contagious delta variant of the COVID-19 coronavirus has ripped through this unprotected population like California wildfire, overwhelming hospitals in parts of the country and dampening the economic recovery that was starting to take hold.  FILE – In this Aug. 26, 2021 file photo, a syringe is prepared with the Pfizer COVID-19 vaccine at a mobile vaccine clinic in Santa Ana, Calif.The United States has the highest death rate and the second-lowest vaccination rate among major industrialized nations, according to ourworldindata.org. “This is a pandemic of the unvaccinated,” Biden said. The United States is also unusual among industrialized nations for the level of political division over pandemic measures.  Resistance to COVID-19 restrictions that started among conservatives during the Trump administration has persisted under Biden. Republican elected officials have pushed back against mask and vaccine mandates as unconstitutional infringements of personal liberty. The Republican governors of Texas and Florida have barred local school districts from requiring masks in classrooms.  Biden’s new plan will require teachers and federal employees to be vaccinated. It mandates that private businesses with more than 100 employees must require their workers to get the shots or be tested weekly.  Biden took aim in his speech Thursday at “elected officials actively working to undermine the fight against COVID-19.”  Those officials shot back. “See you in court,”  Republican South Dakota Governor Kristi Noem wrote on Twitter. South Dakota will stand up to defend freedom. FILE – In this Tuesday, Aug. 10, 2021, file photo, students, some wearing protective masks, arrive for the first day of school at Sessums Elementary School in Riverview, Fla.‘Not safe’ Overall, public health officials said the Biden administration is doing the right thing. The administration is mandating vaccines under its purview to make workplaces safe.  “It is not safe at this moment to return to a workspace where there are large numbers of unvaccinated people. It is just not,” said Brown University School of Public Health Dean Ashish Jha at a news briefing. “While I appreciate the rights of people who choose not to be vaccinated, people also have a right to be able to go to work and not get infected, not get sick and not die.” Jha said the administration also should have required vaccination at colleges and universities and for interstate travel, areas where the federal government has jurisdiction.  “These things largely work,” he said. “People don’t love them, but they work.”
