COVID vaccines and 'immune system memory'

+ honeybee vaccine; biomechanics of cochlear implants US Edition - Today's top story: Even bivalent updated COVID-19 boosters struggle to prevent omicron subvariant transmission – an immunologist discusses why new approaches are necessary [View in browser]( US Edition | 25 January 2023 [The Conversation] [The Conversation]( Immunologist Matthew Woodruff reports today that the bivalent vaccines for COVID-19 have been disappointing in that they have not reduced transmission of the omicron variant much better than previous vaccines. His explanation as to why [updated vaccines can potentially inhibit a body’s immune response to a new strain of a pathogen]( is particularly timely given the FDA’s proposal to recommend a yearly vaccine for COVID-19, a change that could actually help researchers better understand this problem. “A once-yearly approach to COVID-19 vaccination opens the door for more straightforward studies on how [immune system] memory to each vaccine influences the next,” he writes. You may have seen headlines recently about a honeybee vaccine, which might conjure up images of sticking a tiny needle into an insect. University of California, Davis, agricultural researcher Jennie Durant, who specializes in honeybee health, explains how the [trial vaccine actually works against the bacterial disease American foulbrood]( and what’s at stake for these very important pollinators. “Honeybees face many urgent threats, including Varroa mites, climate change and poor nutrition, which makes this vaccine an exciting new development,” she writes. Fellow editors in our newsroom know all too well how preoccupied I’ve been in recent years over misinformation, conspiracy theories and the general fracturing of our society over dueling versions of what is the truth. Psychologist Craig Foster writes about a class he developed to explain how people believe pseudoscience in particular. The article – like the class – gets into some of the [psychological traps that we all are vulnerable to](, such as relying heavily on anecdotes or social interactions, when making sense of scientific information.
