Well i would sacrifice myself in terms of skipping the flu vaccine if there was a shortage and the higher risk groups needed it, but lately in the US there has been plenty. It still increases my emet anxiety even though I've been the "calm voice of reason" about flu not typically causing v* and a lot of bad things would happen for me if I were to be unwell for the amount of time that flu usually takes to recover, plus I'd probably give it to everybody at work and my bioprocess lab partner and heaven only knows who else.
