US CDC advisers weigh lower age recommendation for RSV vaccines
April 16 (Reuters) - The U.S. Centers for Disease Control and Prevention's vaccine experts are expected to vote on expanding access to respiratory syncytial virus shots in the second round of their meeting on Wednesday.
Guidelines from the Advisory Committee on Immunization Practices help physicians decide what vaccines to recommend to patients and are also used for determining insurance coverage in the U.S.

The country's health regulator has approved three vaccines for RSV — GSK's (GSK.L), opens new tab Arexvy, Moderna's (MRNA.O), opens new tab mRESVIA and Pfizer's (PFE.N), opens new tab Abrysvo.
RSV typically causes cold-like symptoms, but is also a leading cause of pneumonia in toddlers and older adults. An estimated 15,000–20,000 annual RSV-associated hospitalizations occur in the U.S. in adults aged 50–59 years, according to the CDC.
The panel was initially due to meet in February but the meeting was delayed just days after Robert F. Kennedy Jr., a long-time vaccine skeptic, became the head of the U.S. Department of Health and Human Services. The session was postponed to allow for public comment, the HHS had said.
The experts are due to vote later on Wednesday on whether to recommend a single dose of RSV vaccines to adults aged 50 to 59 years who are at an increased risk of the severe disease. The CDC currently recommends the vaccine for adults 75 years and older and at-risk adults aged 60 to 74 years.
The CDC had decided to hold off on recommending RSV shots for adults under age 60 last year.
GSK's Arexvy and Pfizer's Abrysvo are approved for the prevention of lower respiratory tract disease caused by RSV in adults aged 50 to 59 and 18 to 59, respectively, who are at an increased risk of the disease. Moderna's application for at-risk adults aged 18 to 59 years is under review by the U.S. Food and Drug Administration.
The panel will also vote on recommendations for use of chikungunya, a mosquito-borne disease, and meningococcal vaccines.
On Tuesday, it discussed narrowing recommendations on the use of COVID-19 booster shots for the upcoming immunization campaign.

How to actually get a good night's sleep
Getting a good night of shut eye can often seem like a Herculean task. Smartphones provide an enticing distraction — whether you're laughing at a funny YouTube video or texting with friends — and the noise and light pollution can interrupt our body clocks. But, there's no one secret to perfect sleep, and everyone is different. Some people can fall asleep in an instant (even if that seems unfair), while others stare at the ceiling for hours. 'As a nation we are not getting enough sleep,' Dr. Wayne Giles, the former director of the Centers for Disease Control and Prevention's Division of Population Health, previously cautioned. But, what is enough, why is it important, and are there rules we can follow to get it? What is a good night's sleep? People need continuous hours of restful sleep. The American Heart Association says you want multiple cycles of all five stages of sleep, advancing into deep sleep. The two main stages of sleep are rapid eye movement (REM) and non-REM. REM sleep is thought to aid in the development of the central nervous system and protect against dementia. The amount of sleep each person needs will vary and changes as we age, but adults should get between seven and nine hours of sleep per night. Otherwise, you will feel tired throughout the week. About a third of U.S. adults don't get enough sleep and many older adults don't sleep well. Sleep disorders are common, but sleep can also be disrupted by chronic health conditions. 'Older adults have different sleep patterns. They tend to sleep more lightly and may wake earlier in the morning,' Cleveland Clinic's Dr. Michelle Drerup said. 'But you still need the same amount of sleep over 24 hours, so if you're sleeping less at night, you might need a nap during the day.' Why do we need it? A good night's sleep can impact memory, adaptability, and brain function. Without enough sleep, symptoms of depression, seizures, high blood pressure, and migraines can worsen. Peoples' immunity is compromised. A lack of sleep can raise our propensity for obesity, heart disease, and type 2 diabetes, according to Harvard Medical School. People who don't get enough are also at an increased risk of falls or accidents. Even just one night without sleep can create a prediabetic state in an otherwise healthy person, according to Johns Hopkins University. Three nights without sleep can hurt your heart, a recent study found. 'Sleep influences many aspects of health, including mood, cardiovascular health, metabolic health, and increasingly we recognize it is important for brain health,' Dr. Mark Wu, a professor of neurology, medicine, and neuroscience at Johns Hopkins University, told The Independent. 'At Hopkins, for example, we have been investigating the connection between sleep and Alzheimer's disease, and the data suggest that poor quality and insufficient sleep can be a risk factor for Alzheimer's disease.' What can we do to get it? Many experts recommend similar steps — and like all good advice, the hard part is following it consistently. Getting exercise in the morning can help maintain your body's clock. Sticking to a schedule and pre-sleep routine can reinforce your body's sleep-wake cycle, according to Mayo Clinic. If you have trouble sleeping one night, try not to sleep later or nap the next day. You will sleep better that night. Federal health officials also advise people keep their bedroom quiet and cool, and turn off their electronic devices at least 30 minutes before bedtime. Bright lights can disrupt your body's natural sleep-wake functions, also known as your circadian rhythm. Dr. Matthew Walker, a professor of neuroscience and psychology at U.C. Berkeley, said in an email shared with The Independent that the room should be at around 65 degrees Fahrenheit. Reduce caffeine after lunch and don't drink before bed. Nicotine is also a negative, Wu said. 'Most people can get good sleep, but there are many factors that can influence sleep, like pain, mood disorders like anxiety, depression, stress,' he explained.

At least 1.7 million eggs recalled as CDC and FDA investigate multistate salmonella outbreak
The Centers for Disease Control and Prevention and the U.S. Food and Drug Administration are investigating a multistate Salmonella outbreak linked to at least 1.7 million eggs, according to a news release issued on Saturday. The brown cage-free and brown certified organic eggs were distributed by the August Egg Company from Feb. 3 through May 15 to retailers in nine states — California, Nevada, Washington, Arizona, Nebraska, New Mexico, Illinois, Indiana and Wyoming, per the FDA. In an announcement issued Friday, the Hilmar, California-based distribution company recalled 1.7 million eggs, which have sell-by dates ranging from March 4 to June 19 and were sold at retailers including Walmart and Safeway, as well as under many different brands that can be seen here. So far, the outbreak has sickened 79 people in New Jersey, Kentucky, Nebraska, Nevada, Arizona, Washington state and California, the CDC said. At least 21 people have been hospitalized, and no deaths have been reported. 'This outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely much higher than the number reported,' the CDC said. 'This is because many people recover without medical care and are not tested for Salmonella.' Salmonella is a type of bacteria that can make people sick if they consume contaminated food and water, or touch animals, their fecal matter or the areas they live in, according to the CDC. It is 'a leading cause of food-borne illness, hospitalizations, and deaths in the United States and worldwide,' causing about 1.35 million infections in the U.S. every year. Symptoms include diarrhea, fever and stomach cramps and can start six hours to six days after consumption of the bacteria. Children under five, the elderly and people with weakened immune systems can become seriously ill as a result of contracting salmonella. The CDC is advising anyone who has the recalled eggs in their home to throw them away or return them to the retailer that sold them. Businesses with recalled eggs should not sell or serve them, and should sanitize any item or surface that came into contact with the eggs. The August Egg Company said it began taking its eggs to an 'egg-breaking facility' to pasteurize them and kill pathogens after learning about the salmonella concern. 'August Egg Company's internal food safety team also is conducting its own stringent review to identify what measures can be established to prevent this situation from recurring,' the company said in a statement. 'We are committed to addressing this matter fully and to implementing all necessary corrective actions to ensure this does not happen again.' This isn't the only salmonella outbreak the U.S. is currently grappling with. Last month, the FDA announced a recall of cucumbers grown by Bedner Growers and distributed by Fresh Start Produce Sales due to a salmonella outbreak that has sickened 45 people and hospitalized 16 across 18 states. The FDA's investigation into the cucumbers is ongoing.
