Q: Paragraph: The public-private partnership includes the World Health Organization, UNICEF, the Bill & Melinda Gates Foundation and the World Bank, among others. The funding announcement was made after a meeting of GAVI's board. GAVI said the investment, which it called an estimate, will be provided between now and 2025. Since the current outbreak in eastern Congo was identified last August, health officials have immunized more than 255,000 people with a recently licensed vaccine made by Merck. To date there have been nearly 3,200 confirmed Ebola cases, including more than 2,200 deaths, in what has become the second deadliest Ebola outbreak in history. Dr. Ngozi Okonjo-Iweala, chair of Gavi's board, called the creation of the Ebola vaccine stockpile a "historic milestone in humanity's fight against this horrific disease." GAVI said "a coordinating mechanism" to decide how and when vaccines will be used will be established with partner organizations. There are similar stockpiles for vaccines against yellow fever, meningitis and cholera. Those limited shots are doled out to developing countries by WHO, UNICEF, the Red Cross and Doctors Without Borders after receiving technical advice from others. The Ebola vaccine stockpile will be available to all countries, but only developing countries will be able to get vaccines for free in addition to support for the logistical costs of mounting vaccination campaigns. Jason Nickerson, a humanitarian affairs adviser at Doctors Without Borders, said the new stockpile would change how officials respond to future Ebola outbreaks. "Knowing how many doses of the vaccine exist in the world, and then being able to get a supply of them to high-risk countries in a very quick way, gives us another tool to respond to these outbreaks," he said. Earlier this year, the medical charity publicly called for an independent committee to oversee Ebola vaccination efforts in Congo, saying WHO sometimes used arbitrary criteria to determine who would get immunized. It said the fact that Ebola was continuing to spread despite the large number of people vaccinated was a damning assessment of the response. Containing this outbreak has been complicated by violence and misunderstandings in a part of Congo that had never reported an Ebola case before. Last week, response activities were suspended after attacks killed four Ebola responders, including a member of a vaccination team. Multiple rebel groups operate in eastern Congo and the region has been described as a war zone. WHO has warned continued attacks on health workers and Ebola clinics could undermine attempts to curb Ebola and prompt a resurgence of the disease. Claim: Vaccine group announces creation of Ebola vaccine stockpile.

A: The vaccine alliance GAVI announced Thursday it would invest $178 million to create a global stockpile of about 500,000 Ebola vaccines, a decision that health officials say could help prevent future outbreaks from spiraling out of control.

Q: Paragraph: The Paris regional administration suspended the job of removing hazardous substances from the fire-ravaged Paris cathedral last month under pressure from labor inspectors concerned about health risks for workers. The administration had said that when the lead-removal work resumed, stricter safety procedures, new equipment and allowing much fewer workers inside at a time would "prevent any release of polluting elements to the outside." But representatives from environmental groups and the CGT union said at a news conference Monday they don't think the government safeguards go far enough. They asked for a regularly updated chart showing the level of lead in the air. Labor and environmental groups are also pushing for the creation of a medical center to monitor of firefighters, workers and residents. Paris Deputy Mayor Anne Souyris said updated measurements of lead levels are set for release on Tuesday. The decontamination work is scheduled to resume Wednesday, starting with the square in front of Notre Dame and adjacent streets, Souyris said. Hundreds of tons of lead that was in Notre Dame's spire and roof melted during the April 15 fire, which came close to destroying the cathedral. Lead levels remain elevated at some spots inside and in the soil of the adjacent park and forecourt, according to the Paris regional health agency. Those areas have been closed to the public since the fire. The environmental activists and union officials said they want a containment shield built over Notre Dame to keep more lead from being released into the atmosphere. "For the efficiency of the decontamination measures within the area, it is absolutely necessary that the site is confined", Annie Thebaud-Mony, co-founder of health and environment group Henri Pezerat, said. Notre Dame rector Patrick Chauvet acknowledged that lead can escape into the environment from a big hole in the cathedral's roof but ruled out building a containment shield before the decontamination work resumes. Paris authorities ordered new checks of schools and day care centers in the Notre Dame neighborhood and recommended blood tests for children under age 7 and pregnant women who live nearby. Children are especially vulnerable to health problems from lead poisoning and exposure. Claim: France: Groups want Notre Dame enclosed during lead cleanup.

A: Environmental groups and one of France's largest labor unions called Monday for a containment shield and other safety measures to ensure decontamination work at Notre Dame Cathedral does not expose workers and residents to unsafe levels of lead.

Q: Paragraph: New Hampshire recently set some of the nation's toughest standards for perfluoroalkyl and polyfluoroalkyl substances, collectively called PFAS, but a judge temporarily blocked enforcement in November after chemical company 3M sued. The New Hampshire standard limits one chemical to a maximum of 12 parts per trillion and another to 15 parts per trillion, far lower than the 70 parts per trillion the Environmental Protection Agency has advised for the chemicals. Sanders, a Vermont senator, said instead of spending millions on lawsuits to gut clean water rules, such companies should be paying to clean up contamination. He said as president, he will create national clean water standards for PFAS and other chemicals in an effort to guarantee clean drinking water "as a human right." "Corporate greed is threatening one of the most basic necessities of life: clean water," he said in a statement. "Not only will we support state efforts to enforce stronger clean water laws, we are going to create federal clean water standards that force these companies to clean up their mess." More than 700 homes in New Hampshire whose drinking water was contaminated by PFAS have been connected to new water, and the state estimates that more than 100,000 other people eventually could be affected. The contamination is the result of the chemicals leaking into groundwater from industrial facilities, as well as a former Air Force base. Studies have found potential links between high levels in the body of one form of the contaminants and a range of illnesses, including kidney cancer, increased cholesterol levels and problems in pregnancies. 3M Co., based in St. Paul, Minnesota, said in a statement Tuesday that it "supports appropriate science-based regulations of PFAS" and therefore backs "consideration of an enforceable, science-based national drinking water standard" for the toxic chemicals. "A consistent and unified federal policy based on sound science can help avoid the confusion and uncertainty of a state-by-state patchwork of regulations," the company said. ___ Catch up on the 2020 election campaign with AP experts on our weekly politics podcast, "Ground Game." Claim: Sanders says he'll enact national drinking water standards .

A:
Democratic presidential hopeful Bernie Sanders said Tuesday that he would enact federal drinking water standards for a group of toxic chemicals that have caused widespread contamination in New Hampshire and other states.
