The Food and Drug Administration is investigating an outbreak of Listeria that has killed at least one person.The FDA, CDC and public health officials are looking into ten cases of Listeria monocytogenes infections reported in Florida, Massachusetts and New York. One person has died, the only available information is that the person lived in Florida.Genome sequencing of the Listeria bacteria isolated from those infected shows the ten people in this outbreak are more likely to share a common source of infection, according to the FDA. Samples were taken from patients between August 6 and October 3.In interviews with nine of the infected people, they all reported eating Italian-style meats recently, like salami, mortadella, or prosciutto, according to the FDA.Public health investigators have not found a common type of deli meat or common supplier among the patients at this time.The patients in this outbreak range in age from 40-to-89 years old, and all of them needed to be hospitalized.Listeria can cause different symptoms, depending on the person and part of the body affected, according to the Centers for Disease Control and Prevention. Symptoms include headache, stiff neck, confusion, loss of balance, fever and muscle aches. 1251

The FDA announced on Friday that it has issued an emergency use authorization for a second coronavirus vaccine. Its approval comes just one week after the FDA gave an emergency use authorization for a similar vaccine by Pfizer. That vaccine began distribution earlier this week. Moderna’s vaccine has been hailed as a medical breakthrough. The vaccine has been considered 94.1% effective against the virus. According to Moderna, none of the thousands who were given two shots of the vaccine had severe COVID-19 symptoms. That is compared to 30 patients who were given a placebo who had symptoms.In order to obtain an emergency use authorization, the FDA weighed the vaccine’s benefits against possible side effects. An emergency use authorization is not a full FDA approval, but it allows those outside of a clinical or hospital setting to obtain the vaccine. “With the availability of two vaccines now for the prevention of COVID-19, the FDA has taken another crucial step in the fight against this global pandemic that is causing vast numbers of hospitalizations and deaths in the United States each day,” FDA Commissioner Stephen M. Hahn said in a statement. “Through the FDA’s open and transparent scientific review process, two COVID-19 vaccines have been authorized in an expedited timeframe while adhering to the rigorous standards for safety, effectiveness, and manufacturing quality needed to support emergency use authorization that the American people have come to expect from the FDA. These standards and our review process, which are the same we have used in reviewing the first COVID-19 vaccine and intend to use for any other COVID-19 vaccines, included input from independent scientific and public health experts as well as a thorough analysis of the data by the agency’s career staff.”According to Moderna, approximately 20 million doses will be delivered to the U.S. government by the end of December 2020. Moderna said it expects to have between 100 million and 125 million doses available globally in the first quarter of 2021, with 85-100 million of those available in the U.S.While the vaccine could nearly eliminate the number of hospitalizations and deaths associated with the virus, the shot might result in some symptoms.In an interview with CNN last month, Operation Warp Speed chief scientific adviser Moncef Slaoui said that 10 to 15% of those immunized had noticeable side effects.“Most people will have much less noticeable side effects. That frankly -- in comparison to a 95% protection against an infection that can be deadly or significantly debilitating -- I think is an appropriate balance," he told CNN. 2648

The FBI held an unforeseen news conference on Wednesday to say that Iran and Russia have been leading a misinformation campaign ahead of this year’s election.Although the sudden nature of Wednesday’s news conference made the announcement seem urgent, intelligence community officials have been warning of interference by Iran, China and Russia for months.Director of National Intelligence John Ratcliffe said that the countries obtained voter registration information, and then used that data to direct misinformation toward voters. Ratcliffe, along with FBI Director Christopher Wray, would not take any questions.Voter registration information is generally public information. Information like voters’ names, addresses and voting history are generally available nationwide. It is unclear if Iran and Russia received information that is publicly available."We have already seen Iran sending spoofed emails designed to intimidate voters,” Ratcliffe said.Ratcliffe claimed that the emails worked to hurt Trump's campaign, but House Democrat Ted Lieu, a member of the Intelligence Committee, questioned how the emails were intended to hurt Trump's campaign. 1164

The FDA said on Wednesday that some vials of the Pfizer coronavirus vaccine, which began being administered to health care workers earlier this week, are overfilled with doses. These doses, the FDA says, can be used for additional vaccinations, which will help expand the supply.Each vial of the Pfizer vaccine contains five doses. But after the vaccine is thawed and administered, those administering the vaccine discovered it is possible to get a sixth, or even seventh dose from the vaccine.This discovery could potentially allow more health care workers to become vaccinated, extending the supply of the vaccine.“However, since the vials are preservative free, it is critical to note that any further remaining product that does not constitute a full dose should not be pooled from multiple vials to create one,” the FDA said.A Pfizer spokesperson said that each dose of the vaccine must contain .3 mL of the vaccine. The spokesperson said that the amount of vaccine in each vial varies, depending on what type of needles and syringes are being used.According to FDA data, the federal government has allocated 2.9 million doses of the vaccine for the first round of distribution. Those being vaccinated will need to return in 21 days to get a booster in order for the vaccine to be fully effective. 1310

The Federal Bureau of Investigation is warning holiday shoppers to be aware of increasingly aggressive and unorthodox scams designed to steal money and personal information.Online shopping scamsIf a deal looks too good to be true, officials say it probably is.FBI Pittsburgh said Monday that consumers should steer clear of unfamiliar websites that offer unrealistic discounts on brand name merchandise. Scammers frequently prey on holiday bargain hunters by advertising “one-day only” promotions from recognized brands.“Without a skeptical eye, consumers may end up paying for an item, giving away personal information, and receive nothing in return except a compromised identity,” the FBI wrote in a press release.Payment red flagsThe FBI says to be cautious of sellers and websites that demand payment solely through gift cards.“Scammers sometimes encourage shoppers to conduct wire transfers, allowing criminals to quickly receive illicit funds,” the bureau wrote.It’s best to use credit cards, because they provide several layers of security against fraud and are typically the safest way to conduct online shopping.Charity scamsWhile others are focused on giving during the holiday season, others are ready to take advantage of that generosity.“Charity-related frauds increase during the holidays as individuals seek to donate money to those less fortunate,” said the FBI.Criminals have been known to use phone calls, email campaigns, and fake websites to solicit on behalf of fraudulent charities. These scammers target people who want to donate to charity, then hoard their well-intentioned donations while those most in need never see a dime.FBI tips to avoid holiday fraud schemes:Before shopping online, secure all financial accounts with strong passwords or passphrases. Additionally, the FBI recommends using different passwords for each financial account.Check bank and credit card statements routinely, including after making online purchases and in the weeks following the holiday season.Never give personal information— such as your date of birth, Social Security number, or billing addresses— to anyone you do not know.Be wary of promotions and giveaways that request your personal information.Prior to donating to any charity, verify that they have a valid Taxpayer Identification number by visiting their website or calling the charity directly. 2373
