Paragraph: Moncef Slaoui, a former GlaxoSmithKline executive, will lead “Operation Warp Speed,” Trump’s push to accelerate the vaccine development process for COVID-19, according to an administration official. Slaoui is to serve in a volunteer capacity, and will be assisted by Army Gen. Gustave Perna, the commander of United States Army Materiel Command. The move comes as the president and White House aides hope to produce vaccines for the coronavirus faster than what many scientists believe is realistic. The administration is aiming to have 300 million doses to distribute to Americans by the end of the year, believing a reliable vaccine is the only way to promote an economic rebound. “Operation Warp Speed” is operating largely independently of the existing White House coronavirus task force, which is also shifting its focus toward vaccine development. The initiative is being promoted by White House senior adviser Jared Kushner, and involves officials from the Defense Department and the Department of Health and Human Services. On Tuesday, Dr. Anthony Fauci, the government’s top infectious disease expert, said a vaccine would not be available by the beginning of the next academic year. “The idea of having treatments available or a vaccine to facilitate re-entry of students into the fall term would be something that would be a bit of a bridge too far,” he said, “even at the top speed we’re going.” Claim: Trump to name former pharma exec as vaccine czar.
President Donald Trump is set to name a former pharmaceutical executive to lead his administration’s all-out effort to produce and distribute a coronavirus vaccine by the end of the year.

Paragraph: Some 100 medical workers are reported to have died from the disease so far, including many nurses, Howard Catton, ceo of the International Council of Nurses, told a news briefing. The world’s 28 million nurses, 59% of all health workers, were overstretched before the crisis began, the WHO, the Nursing Now campaign, and Geneva-based council said in the first “State of the World’s Nursing Report”. Some have become targets out of people’s fear of contagion. “We have picked up reports around the world of abuse, harassment of health workers, we had one case of somebody being spat on as well. It is completely unacceptable, reprehensible,” Catton said. He called for governments to have a “zero tolerance approach” to such abuse and to ensure that public health messages are clear and fact-based. Giorgio Cometto of WHO’s health workforce department said it was a relatively new phenomenon “whereby health workers are seen as a potential risk, as a potential threat as opposed to being a solution to the current crisis”. “This really reinforces the need to have adequate communication for the public as well as specific measures to be put in place to protect health workers particularly in the context of the response to the current pandemic,” he said. Baroness Mary Watkins, chair of Nursing Now, said nurses have been attacked previously during outbreaks of Ebola and the AID-HIV epidemic. Referring to COVID-19, she said: “We have not had active violence that I know of in the UK, but we have had people trying to take nurses’ badges because they have been allowed to go into supermarkets early to buy food before going on their shift... That seems to have had a stop put to it. “But there has been a very very clear directive from the police in many countries that attacking a health care worker is unacceptable. We need to keep pressure up,” Watkins added. There is still a global shortage of nearly 6 million nurses, mainly in low- and lower-middle income countries, where the number of new recruits barely keeps pace with population growth, the report said. Nurses are particularly lacking across Africa, in Afghanistan, Pakistan, Yemen, and Venezuela, it added. Claim: Nurses must be protected from abuse during coronavirus pandemic: WHO, nursing groups.
Authorities must protect nurses and other health workers from harassment and attacks compounding the already heavy toll they are paying in the pandemic, the World Health Organization (WHO) and top nursing officials said on Tuesday.

Paragraph: In the interview, Bolsonaro also stuck to the government’s assertion that a Greek freighter caused the oil spill scattered across beaches along 1,300 miles (2,100 kilometers) of coastline even after the shipowner’s denial of any leakage from its vessel. “All signs point to this Greek cargo ship. All of them,” he told Record TV, adding that the leak, “by all accounts looks like it was criminal.” Brazil’s government has been striving to investigate the cause of the spill that has hit 321 beaches along the northeast coast since early September, hurting fishing and tourism. Authorities have described the spill as one of the country’s worst environmental disasters. The crude’s density renders it invisible from above, making it hard to track its origin or to have a clear picture of the amount of oil yet to reach Brazil’s coast. Some 4,000 tons of oil has been collected from northeastern beaches thus far, according to a statement Sunday from the Navy, Brazil’s environmental regulator, and the national petroleum agency. “To say how much oil there still is very difficult to say,” Commander Leonardo Puntel of the Brazilian Navy said at a press conference on Monday. “Since the oil is underwater, we don’t know if there’s still a lot or a little. There is effectively no correct and accurate way to monitor these oil spots,” he said, adding that they have seen a decrease in oil arriving onto beaches in recent days. He called the disaster “unprecedented.” “There is no case in the world of a large-scale oil spill where the origins are totally unknown. This case has no parallel, we don’t know who polluter is,” Puntel said. Brazil’s defense minister, Gen. Fernando Azevedo e Silva, also stressed how challenging it is to calculate the spill’s scope. “It is not detectable by satellite. ... It is imperceptible. We do not know how much will still come,” he said. David Zee, an oceanographer at the State University of Rio de Janeiro, said that the 4,000 tons of collected oil is “just the tip of the iceberg,” both because the cleanup effort is mostly limited to sandy beaches in populated areas and also because a large portion of spilled oil is likely spread deep beneath the ocean’s surface. Furthermore, when currents bring oil to sandy shores, it is relatively easy to collect, while is nearly impossible to remove from corals and mangrove forests, which make up part of the affected area, Zee said. Brazilian prosecutors have named Greek shipping company Delta Tankers Ltd as a suspect of the leak’s origins. The company issued a statement earlier saying it found no evidence of leakage after reviewing the ship’s cameras and sensors. “This material will be willingly shared with Brazilian authorities, should they contact the company regarding this investigation. So far, no such contact has been made,” the statement said. Federal Police officer Franco Perazzoni said at Monday’s press conference that the company will be officially notified via Interpol. Brazilian prosecutors said previously that Delta’s oil tanker, named Bouboulina, was navigating through Brazilian waters at the time and location of the spill. The ship was carrying oil from Venezuela to Malaysia. In a search order seen Friday by The Associated Press, Brazilian prosecutors said “there is no indication of another boat” that could have discharged the Venezuelan crude into the sea. Brazilian armed forces along with environmental protection agencies and petroleum authorities are leading an operation to clean, monitor and investigate the oil spill. Several public universities are conducting research about the spill’s origins and impact. Television footage has also shown volunteers flocking to beaches to help with the cleanup, often without government supervision. Of particular concern at the moment is the Abrolhos national marine park, home to Brazil’s largest coral reefs. Authorities said Sunday night that they had removed the fragments of oil that had appeared in the park and so far no new traces had been found. “A very small amount of oil arrived on November 2, on November 3 only a few fragments remained, today there’s none,” Puntel said in the Monday press conference. “Will more oil fragments come? Maybe.” Claim: Brazil reckons with new oil spill mystery: When will it end?.

Brazilian authorities said on Monday that they have no way of knowing how much more oil will wash ashore the country’s northeastern coast, despite President Jair Bolsonaro’s ominous warning during a Sunday night TV interview that “the worst is yet to come.”
