There won't be a vaccine this year. That's pretty clear. Vaccines take a long time to get tested under the best of circumstances. If not tested properly and administered to millions of people (which they'd have to be in order to have effect) they could cause a lot of adverse reactions and deaths all on their own. Don't take this as antivax bullshit: I do take a flu vaccine every year myself, including this year, my kid is fully vaccinated also (+ flu vaccine last year - I told him to "be a man"). It's just the nature of the beast - immune system can really fuck one up once it really gets going.
