'Just in case': Vaccine makers say bird flu shots for humans can be made in months
India TodaySome 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. NEW APPROACHES In a pandemic, vaccine manufacturers would shift production of seasonal flu vaccines and instead make shots tailored to the new outbreak when needed. Many of the potential pandemic shots are pre-approved by regulators, based on data from human trials showing the vaccines are safe and prompt an immune response, a process already used with seasonal flu vaccines. Moderna’s mRNA vaccine research actually began with pandemic flu, and was modified for COVID, said Raffael Nachbagauer, executive director of infectious diseases at Moderna. The company plans to launch a small human trial of an mRNA pandemic flu vaccine tailored to the new avian influenza subtype in the first half of 2023, he said, adding Moderna could respond “very quickly” in an outbreak scenario.
