LONDON (AP) — Scientists at Oxford University say their experimental coronavirus vaccine has been shown in an early trial to prompt a protective immune response in hundreds of people who got the shot. British researchers first began testing the vaccine in April in about 1,000 people, half of whom got the experimental vaccine. Such early trials are usually designed only to evaluate safety, but experts were also looking to see what kind of immune response was provoked. In research published Monday, scientists said that they found their experimental COVID-19 vaccine produced a dual immune response in people who got the shot. 637

LOS ANGELES (AP) — California environmental officials say a popular agricultural pesticide they say has been linked to brain damage in children will be banned after next year under an agreement reached with its manufacturer.Under the deal announced Wednesday, all California sales of chlorpyrifos will end on Feb. 6, 2020.Farmers will have until the end of 2020 to exhaust their supplies.The pesticide is used on numerous crops in the nation's largest agriculture-producing state, including alfalfa, almonds, citrus, cotton, grapes and walnuts.State regulators say the pesticide has been linked to health defects in children, including brain impairment.Officials say they are budgeting million to help manufacturers develop a safer alternative.The pesticide's manufacturer, Corteva Agriscience, says it reached the agreement "in the best interests of the affected growers." 884

LONDON — U.K. regulators say people who have a “significant history’’ of allergic reactions shouldn’t receive the new Pfizer-BioNTech vaccine while they investigate two adverse reactions that occurred on the first day of the country’s mass vaccination program. Stephen Powis, the national medical director for the U.K.'s National Health Service in England said Wednesday that health authorities were acting on a recommendation from the Medical and Healthcare Products Regulatory Agency. He says the agency has advised, on a precautionary basis, that "people with a significant history of allergic reactions do not receive this vaccination." Powis added that both people are recovering well.Dr. June Raine, head of the U.K.'s Medical and Healthcare Products Regulatory Agency, told Parliament on Wednesday that the reactions were not seen in clinical trials for the drug.“We know from the very extensive clinical trials that this wasn’t a feature,” Raine said, according to the Associated Press. “But If we need to strengthen our advice, now that we have had this experience with the vulnerable populations, the groups who have been selected as a priority, we get that advice to the field immediately.The FDA is currently weighing whether to approve the Pfizer-BioNTech vaccine for emergency use in the United States. 1325

LOS ANGELES (CNS) - An initiative to split California into three states has received enough signatures to qualify for the November ballot, its author said Wednesday.Venture capitalist Tim Draper said backers of what he has dubbed "CAL 3" would submit petitions with more than 600,000 signatures to election officials next week. The initiative needs signatures from 365,880 registered voters - five percent of the total votes cast for governor in the 2014 election - to qualify for the ballot."This is an unprecedented show of support on behalf of every corner of California to create three state governments that emphasize representation, responsiveness, reliability and regional identity," Draper said.   Splitting California into three states would require congressional approval. One proposed state would be called California or a name to be chosen by its residents after a split. It would consist of Los Angeles, Ventura, Santa Barbara, San Luis Obispo, Monterey and San Benito counties. A second state, Southern California or a name to be chosen by its residents, would consist of Orange, Riverside, San Bernardino, San Diego, Imperial, Kern, Kings, Fresno, Tulare, Inyo, Madera and Mono counties.   The remaining 40 counties would be part of the state of Northern California or a name chosen by its residents.   Draper said he conceived the initiative out of a belief that "the citizens of the whole state would be better served by three smaller state governments while preserving the historical boundaries of the various counties, cities and towns."   Steven Maviglio, a longtime Democratic Party political consultant who was a co-chair of the effort to oppose Draper's 2014 initiative to split California into six states, told City News Service, "Splitting California into three and creating three new governments does nothing to solve our state's challenges other than tripling them." "CAL 3'' has no connection to efforts to have California succeed from the United States. 2050
