didn't know I had a choice in the matter. thought the flu vaccine was practically a monopoly situation.. I recall hearing something a long those lines the last time a 'shortage' situation developed. Odd thing is, I was aware of the risk of 'live' virus shots simply because a black labrador retriever I once owned developed 'AIHA' after her shots. Barely survived.. totally crippled by the treatment and recovery. anyway, from that point on, I tried (in vain) to opt for 'non live virus' shots for my pets. Typically vet's don't stock them, as there is no demand, and they claimed that getting them in for a single animal was too impractical.. Literally i'd have to pay for a case to offset their risk no one else would opt for them... as they were low demand, and as a result, higher cost.
Anyway, back to the human side of this equation. I only know of two 'brand' names of flu vaccines, and i've only ever seen one distributed in this part of the world. I'll raise the point with my GP next visit, see what he has to say about it
