The NHS has worked out from previous pandemics what percent of the population are likely to contract the flu in the first wave (about 1 in 5) and are now stock piling about 14 million doses of tamiflu. What hasn't been worked out is how to distribute those doses to those with the genuine flu and not just a cold. It is expected that a second wave will come through in the following year. For that wave there should be a vaccine available.
As for me as an individual. No point in getting a flu jab as it won't work against a new flu. I am a GP so would be in contact with cases early on so would expect to get it. Therefore I expect to get ill and rely on getting over it with help from tamiflu.
Learn how to reduce the chance of catching a cold or flu. Some ideas:-
Don't travel by public transport.
Wash your hands very frequently (hands spread most of the germs probably) - especially if you touch something that others regularly touch (door handle etc..)
Make sure rooms are well ventilated if sharing the space with someone who could have a virus (coming, going, carrier state etc.) Note that coughs, sneezes and even speech will spread an aerosol of the germs in the air.
If you get what you think is a bad flu, try to not go to places that would spread it to others.
Stay physically fit - less chance of getting an illness and better chance of getting over it without complications.
