    German man got 217 COVID shots over 29 months—here’s how it went

    Enlarge

    A 62-year-old man in Germany decided to get 217 COVID-19 vaccinations over the course of 29 months —for "private reasons." But, somewhat surprisingly, he doesn't seem to have suffered any ill effects from the excessive immunization, particularly weaker immune responses, according to a newly published case study in The Lancet Infectious Diseases .

    The case is just one person, of course, so the findings can't be extrapolated to the general population. But, they conflict with a widely held concern among researchers that such overexposure to vaccination could lead to weaker immune responses. Some experts have raised this concern in discussions over how frequently people should get COVID-19 booster doses.

    In cases of chronic exposure to a disease-causing germ, "there is an indication that certain types of immune cells, known as T-cells, then become fatigued, leading to them releasing fewer pro-inflammatory messenger substances," according to co-lead study author Kilian Schober from the Institute of Microbiology – Clinical Microbiology, Immunology and Hygiene. This, along with other effects, can lead to "immune tolerance" that leads to weaker responses that are less effective at fighting off a pathogen, Schober explained in a news release.

      COVID is a lot like the flu now, CDC argues in new guidance

    COVID-19 is becoming more like the flu and, as such, no longer requires its own virus-specific health rules, the Centers for Disease Control and Prevention said Friday alongside the release of a unified " respiratory virus guide ."

    In a lengthy background document , the agency laid out its rationale for consolidating COVID-19 guidance into general guidance for respiratory viruses—including influenza, RSV, adenoviruses, rhinoviruses, enteroviruses, and others, though specifically not measles. The agency also noted the guidance does not apply to health care settings and outbreak scenarios.

    "COVID-19 remains an important public health threat, but it is no longer the emergency that it once was, and its health impacts increasingly resemble those of other respiratory viral illnesses, including influenza and RSV," the agency wrote.

      CDC recommends spring COVID booster for people 65 and up

    People ages 65 and up should get another dose of a COVID-19 vaccine this spring, given the age group's higher risk of severe disease and death from the pandemic virus, the Centers for Disease Control and Prevention announced Wednesday.

    Earlier today, an advisory committee for the CDC voted overwhelmingly in favor of recommending the spring booster dose. And late this afternoon, CDC Director Mandy Cohen signed off on the recommendation, allowing boosting to begin.

    "Today’s recommendation allows older adults to receive an additional dose of this season’s COVID-19 vaccine to provide added protection," Cohen said in a statement. "Most COVID-19 deaths and hospitalizations last year were among people 65 years and older. An additional vaccine dose can provide added protection that may have decreased over time for those at highest risk."

      RTO doesn’t improve company value, but does make employees miserable: Study

    For some, having to work from home during the COVID-19 pandemic was stressful. Parents balanced job duties while caring for children. Some struggled to set up a home office and adjust to new tools, like video conferencing. Lonely workdays at home added to social isolation. The line between work and life blurred.

    For others, working from home was a boon—comfort, convenience, flexibility, no commuting or rush-hour traffic, no office-environment distractions. When the acute aspects of the pandemic receded, some who at first struggled began to settle into a work-from-home (WFH) groove and appreciated the newfound flexibility.

    Then, bosses began calling their employees back to the office. Many made the argument that the return-to-office (RTO) policies and mandates were better for their companies; workers are more productive at the office, and face-to-face interactions promote collaboration, many suggested. But there's little data to support that argument. Pandemic-era productivity is tricky to interpret, given that the crisis disrupted every aspect of life. Research from before the pandemic generally suggested remote work improves worker performance—though it often included workers who volunteered to WFH, potentially biasing the finding.

      First state-level look at long COVID reveals the seven hardest-hit states

    Over four years after SARS-CoV-2's debut, researchers still struggle to understand long COVID, including the ostensibly simple question of how many people have it. Estimates for its prevalence vary widely, based on different study methods and definitions of the condition. Now, for the first time, the Centers for Disease Control and Prevention has attempted to estimate its prevalence among adults in each US state and territory. The results again show a wide range of prevalence estimates while revealing the states that were hardest hit as well as those that seem relatively spared.

    Overall, the CDC found that seven states in the South, West, and Midwest had the highest prevalence of long COVID in the country, between 8.9 percent and 10.6 percent: Alabama, Montana, North Dakota, Oklahoma, Tennessee, Wyoming, and, the state with the highest prevalence of 10.6 percent, West Virginia. The results are published today in the CDC's Morbidity and Mortality Weekly Report .

    On the other end of the spectrum, New England states, Washington, and Oregon had lower prevalence rates, between 3.7 percent and 5.3 percent. The lowest rate was seen in the US Virgin Islands with 1.9 percent. Washington, DC, and Guam had ranges between 1.9 percent and 3.6 percent.

      Can you sanitize the inside of your nose to prevent COVID? Nope, FDA says.

    More than four years after SARS-CoV-2 made its global debut, the US Food and Drug Administration is still working to clear out the bogus and unproven products that flooded the market, claiming to prevent, treat, and cure COVID-19.

    The latest example is an alcohol-based sanitizer meant to be smeared inside the nostrils. According to its maker, the rub can protect you from becoming infected with SARS-CoV-2 and other nasty germs, like MRSA, and that protection lasts up to 12 hours after each swabbing. That all sounds great, but according to the FDA, none of it is proven. In a warning letter released Tuesday, the agency determined the sanitizer, called Nozin, is an unapproved new drug and misbranded.

    While ethyl alcohol is used in common topical antiseptics, like hand sanitizers, the FDA does not generally consider it safe for inside the nostrils—and the agency is unaware of any high-quality clinical data showing the Nozin is safe, let alone effective. The FDA also noted that, for general over-the-counter topical antiseptics, calling out specific pathogens it can fight off—like SARS-CoV-2 and MRSA—is not allowed under agency rules without further FDA review. Making claims about protection duration is also not allowed.

      CDC to update its COVID isolation guidance, ditching 5-day rule: Report

    CDC to update its COVID isolation guidance, ditching 5-day rule: Report

    Enlarge (credit: Getty | Thomas Trutschel )

    The Centers for Disease Control and Prevention is preparing to update its COVID-19 isolation guidance, moving from a minimum five-day isolation period to one that is solely determined by symptoms, according to a report from The Washington Post .

    Currently, CDC isolation guidance states that people who test positive for COVID-19 should stay home for at least five days, at which point people can end their isolation as long as their symptoms are improving and they have been fever-free for 24 hours.

    According to three unnamed officials who spoke with the Post, the CDC will update its guidance to remove the five-day minimum, recommending more simply that people can end their isolation any time after being fever-free for 24 hours without the aid of medication, as long as any other remaining symptoms are mild and improving. The change, which is expected to be released in April, would be the first to loosen the guidance since the end of 2021.
