Some interesting news from the BBC this week http://www.bbc.co.uk/news/health-18969338
The National Health Service in the UK has decided to start offering free flu immunisations (via the nasal spray Fluenz) to all 2-17 year olds in the UK. Because of issues with supply this isn't likely to be implemented until 2014.
I haven't looked into the flu mist spray much. Interested in (evidence based) opinions on this choice. I generally trust the NHS to do what's best for the country as a whole (if not the individuals), and they quite openly seem to be saying this isn't about protecting the children themselves from flu (since most healthy children will get through it just fine) but about reducing the amount of flu virus circulating in the UK population to help protect the most vunerable from it.
FYI - currently in the UK injectable flu vaccine is offered free on the NHS to over 65s, pregnant women and those with medical conditions which mean flu could be dangerous. If you aren't in these groups you can buy it from the pharmacy once these groups have had time to get their shots in September/October.
