Vaccinations - 6 monthly or annual?

[chaps89]

Are we mostly back to annual vaccinations following the equine flu outbreak or should we still be doing 6 monthly boosters?
We don't compete, just box out for hacking and school hire so I'm presuming I'm fine for annual jabs again but thought it would be worth checking as haven't seen anything on this for a while and I'm coming up to 6 months for mine.

I've gone back to annual as I'm not going anywhere atm. If I was going to clinics or competitions it would be 6 months.
