ProteqFlu, the live attenuated canarypox equine influenza (EI) vaccine, has had its shelf life extended from 27 to 36 months.

Merial says the increased shelf life is the result of ongoing investment in vaccine research & development, and that the new data underpins the stability of modified live vaccine technology.

Merial highlights that ProteqFlu is the only equine flu vaccine in Europe to include the updated American clade 1 Ohio/03 strain in accordance with the OIE recommendations (2004).
