Dominic Raab has resigned as Brexit Secretary. In a statement he said he “cannot in good conscience support the terms proposed for our deal with the EU.”The pound has plunged on the back of Raab’s surprise resignation. Last night, after the United Kingdom and European Union agreed on the text of a Brexit withdrawal agreement, British Chancellor Phillip Hammond held a conference call with business leaders to convince them the draft agreement was the way forward. But Raab’s resignation has sent the business community back into uncertainty with the threat of a no deal scenario resurfacing.When addressing the House Thursday morning, British Prime Minister Theresa May said Wednesday's deal is not the final Brexit deal. May said that delivering Brexit involves difficult choices. She said she respected the views of those who resigned and thanked them.“There is no deal which delivers the Brexit the British people voted for without this insurance policy,” May said, referring to the Irish border backstop agreement that has infuriated some Brexiters.Two Cabinet ministers, two junior ministers and a parliamentary aide resigned on Thursday morning, just hours after May won approval from her Cabinet for the draft Brexit deal.   1296

During the last few months, many health experts have been talking about reaching “herd immunity” with the distribution of the COVID-19 vaccine. Over the Christmas weekend, Dr. Anthony Fauci said he estimates the country needs to reach 80-85% with the vaccine to attain herd immunity.Here’s what that means.Herd immunity is a concept used in discussions about vaccination, and signifies the threshold needed for a population as a whole to be protected from a virus.The World Health Organization clarifies that herd immunity, or population immunity, “is achieved by protecting people from a virus, not by exposing them to it.”The Mayo Clinic also describes the situation following the 1918 Spanish Flu outbreak. They say people who survived the pandemic were later immune to infection of the H1N1 flu, also referred to as swine flu.Health experts warn that relying on community infection to create herd immunity could be dangerous; there are questions about how long the antibodies created by infection protect against reinfection, and a high level of community infection could lead to overwhelmed medical facilities and a high number of deaths.When the threshold of herd immunity is reached, it means the vast majority of a population is vaccinated and has antibodies, thereby lowering the overall amount of community spread of the virus. It also means portions of the population who cannot get vaccinated are kept safer by the limited spread.What that threshold is varies depending on the virus and the efficacy of the vaccine.According to the WHO, herd immunity against the measles is reached with 95% vaccination, while herd immunity against polio is 80%.Dr. Fauci believes herd immunity for COVID-19 can be reached with around 85% of the population having antibodies. 1778

Earlier this week, both the Centers for Disease Control and Prevention and the Food and Drug Administration investigate an outbreak of salmonella infections across multiple states, possibly linked to imported wood ear mushrooms.The agencies said consumers should be on notice when ordering food with mushrooms because the dry mushrooms, which were likely imported by Wismettac Asian Foods, Inc. of Santa Fe Springs, California, could cause salmonella infections.The agencies say the dry mushrooms were shipped to restaurants in 31 states and Washington, D.C."Consumers can ask restaurants where mushrooms are from before ordering to avoid eating recalled mushrooms," the FDA said.The CDC says 41 reported cases of the salmonella infection in 10 states, and four people have been hospitalized.On its website, Wismettac Asian Foods said they voluntarily recall the 5-pound bags of dried fungus imported from China. 920
