No, not too late for a flu vaccine, but you say you are coming down with the flu now. It won't help you if you already contracted the virus. Are you saying you have flu vaccine in your own fridge? In the US, they don't send home vaccines for self administration, so I am confused. If this is the FluMist (nasal mist), you definitely can't take it once you are a biologic. FluMist is a live vaccine.
I would imagine that the shingles vaccine is available in Europe.
