親愛的馬丁,
The comment in Promed about live virus vaccines was misplaced given the only live virus vaccine being produced is a fowl pox vaccine which acts as a vector for a small part of the influenza virus.
This type of vaccine has been used widely elsewhere in the world and cannot revert to a virulent influenza strain.
