My last post and the thread of answers has been moved to the 'General' board so I am re-asking the following question:
I have obviously missed the timing for the CHV vaccination - my vet never mentioned it.  Is it too late at 23 days?

Unlikely that you'll source any unless your vet is stock piling. There's a national shortage which may not be resolved until October.

I had no problem getting it in, even though my vet had never heard of it. 

Personally, I wouldn't want to give a vaccination in the middle third of pregnancy, when their organs are developing and differentiating, and when birth defects can occur if anything untoward happens. 

So I wouldn't give the 1st vaccination, now, but I would for sure give the vaccination at the end of pregnancy. 

The first vaccination protects against herpes at the start of pregnancy, when it can cause miscarriage and absorption, and the 2nd vaccination protects against it at the end of pregnancy, when it can cause the pups to catch it at birth and then fade away and die in the first week or so afterwards. 

The 2 jabs are not 'boosting' each other, or working together, as far as I can tell - it's just that each jab is quite short-lived and causes the bitch to develop antibodies for about 3-4 weeks afterwards.

So - I'd skip the 1st one, but I would get onto your vet ASAP about ordering in a dose for the end of pregnancy...

When my vet messed up we called the manufacturer who said the first jab is safe to give up to 4 weeks post mating so yes you are OK.  If in doubt get your vet to also call them

Thanks - very helpful

However that was before the problem with the manufacturers and most vets running out. It's like gold dust now.
