Vaccine Makers Prep Bird Flu Shot For Humans 'just In Case'; Rich Nations Lock In Supplies
Some of the world's leading makers of flu vaccines say they could make hundreds of millions of bird flu shots for humans within months if a new strain of avian influenza ever jumps across the species divide. One current outbreak of avian flu known as H5N1 clade 2.3.4.4b has killed record numbers of birds and infected mammals. Human cases, however, remain very rare, and global health officials have said the risk of transmission between humans is still low. (Rigby, 3/20)

Mountain West’s Dry Climates Allow Some Airborne Viruses To Live Twice As Long, Study Finds
Humidity can play a big role in how long airborne viruses can survive, according to a new study out of the University of Colorado Boulder. Researchers released airborne particles of a coronavirus similar to the one that causes COVID-19 into chambers with different levels of humidity. They found the particles remained infectious for twice as long in dry environments – like those in much of the Mountain West. (Gibson, 3/17)
