Ovivac timings

[gavd]

just done the lambs first shot of ovivac, it's looking like i will only have time to do there second shot in three weeks time instead of the recommended 4-6 weeks after the primary jab. Do you guys think the vaccine will still work/has anyone done this ?
Thanks

It's 4-6 weeks later for a reason...

Get it as close to 4 weeks as you can. I expect you'll get some responce at 3 weeks, but not as good as waiting 4-6. Better than doing nothing.
