FWIW~ Dr R recommended the preservative-free flu vaccine this year. I have had the flu vaccine in previous years with only a small, temporary setback in health. The relatively small consequence is much better than getting the flu for me, so I've taken the vaccine for a number of years now. The good news this year is that the preservative-free version (or just this year's combo) gave me absolutely no side effects whatsoever. Worth considering if you, like me, have kids or others bringing pathogens into your home and your rxn to flu vaccines in the past wasn't severe. Naturally, if you've had bad rxns in the past, the vaccine is probably not a good idea.
