CHMP Backs Extended Use of AstraZeneca H5N1 Pandemic Flu Vaccine
The European Medicines Agency's CHMP recommended extending AstraZeneca's H5N1 pandemic flu vaccine to include adults, removing the previous upper age limit. The vaccine, approved in the EU since 2016, is for use during declared pandemics. The decision now goes to the European Commission for final approval.
