I have just had to restart my boys jabs so that I can compete him in RC Team events. Sadly when I first got him at 11 years old he we perfectly up to date (was doing BE) and I was 6 days late once as I didnt realise about these rules.
This year I came to compete in an RC Team and have been told I need to restart his jabs. Very annoying!! and expensive.
Ist primary jab followed by a second no less than 21 & no more than 92 two days after. (Day one is the day after the jab). Third jab no less than 150 no more than 215 days after the second one. Annually thereafter unless (as already stated) competing under FEI rules
