Seniors should avoid this vaccine after deadly complications discovered, FDA says
The Ixchiq vaccination, developed by Valneva to prevent the mosquito-borne chikungunya virus, was approved by the Food and Drug Administration (FDA) in November 2023 as the first of its kind.
The approval applies to anyone aged 18 and older who has a risk of being exposed to the virus.
But the FDA and the Centers for Disease Control and Prevention (CDC) released a safety notice on May 9 recommending that adults over 60 years old pause use of the vaccine due to fatal complications.
'FDA and CDC will continue the evaluation of post-marketing safety reports for Ixchiq,' the release reads.
'While the safety of Ixchiq for use in individuals 60 years of age and older is being further assessed, FDA and CDC are recommending a pause in use of the vaccine in this age group. FDA and CDC will update the public when the agencies complete their evaluation of this safety issue.'

The advisory follows reports of 'serious adverse events,' including neurologic and cardiac events in people who received the vaccine.
Two of 17 events resulted in death from severe complications. One death was caused by encephalitis, or inflammation in the brain, the alert stated.

Those who experienced adverse effects of the vaccine were reported to be between the ages of 62 and 89.
The FDA warned that Ixchiq, which contains a live, weakened version of chikungunya, may cause symptoms similar to the virus.
Typical symptoms of chikungunya include fever, severe joint pain, headache, muscle pain and a rash, according to the CDC.
Most people recover within a week, but some may experience 'severe and disabling' joint pain for weeks or months.

'This virus is in a similar category as dengue or Zika and is carried by the same mosquitoes,' Fox News senior medical analyst Dr. Marc Siegel previously told Fox News Digital.
At the time of the vaccine's approval, the FDA described chikungunya as an 'emerging global health threat,' with at least five million cases reported over the past 15 years.
The FDA plans to conduct an 'updated benefit-risk assessment' for Ixchiq use in those over 60 years of age, according to the notice.

Ice Cream Bars and Frozen Treats Recalled in 23 States Due to Listeria
Skip the ice cream truck for now. Depending on where you live, an innocent ice cream truck could hide a potential threat. Rich's Ice Cream Co., based in West Palm Beach, Florida, recalled 110,292 cases of ice cream bars on June 27. The frozen treats may be contaminated with listeria, a potentially lethal foodborne pathogen. Rich's sells its products to schools and ice cream trucks across the country, so this recall is particularly dangerous for school-age kids. When Rich's first recalled the contaminated ice cream bars, the company sent a note to its distributors but not to the public, according to a Food Safety News report. Nearly three weeks later, on July 17, the United States Food & Drug Administration (FDA) classified the recall as Class II, or 'a situation in which use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote,' per the FDA's website. This classification brought the recall to light and caused a wave of media coverage. Here's what you need to know to keep your family safe. What You Need To Know Take care when ordering treats from an ice cream truck this summer. Listeria bacteria can survive refrigeration and even freezing, according to the United States Department of Agriculture. The following frozen products may contain traces of listeria: Chocolate Crunch Cake Bar Cool Watermelon Bar Cotton Candy Twirl Bar Crumbled Cookie Bar Fudge Frenzy Bar Orange Cream Bar Rich Bar Savagely Sour BlueRaspberry Bar Savagely Sour Cherry Bar Strawberry Shortcake Bar The ice cream bars were all individually packaged in plastic wrappers. There's not much parents can do right now, except err on the side of caution when purchasing from ice cream trucks. The distributors of Rich's ice cream bars sold the frozen treats to schools and ice cream truck vendors in the following states: Alabama Arizona California Florida Georgia Illinois Iowa Louisiana Massachusetts Missouri Nebraska Nevada New Jersey New York Ohio Oklahoma Oregon Pennsylvania South Carolina Tennessee Texas Virginia Wisconsin If you think you or your child has eaten one of the contaminated ice cream treats, monitor for symptoms. Listeria can cause fever and flu-like symptoms, such as muscle aches and fatigue, according to the CDC. Other common symptoms are headache, stiff neck, confusion, and loss of balance. If you experience any of the above, contact your healthcare provider to confirm a diagnosis. Read the original article on SIMPLYRECIPES Solve the daily Crossword
