Dr.O, has there been a finding yet on when a foal whose dam was administered the WNV should receive the first shot?
Thanks, George

This still remains unknown. Fort Dodge said they would have this information for us by now and I do not know why this is taking so long. These are Fort Dodges current recommendations but are not based on any research so may change:
(1) In a high risk situation (in regards to potential exposure to the wild virus), foals born from mares not previously vaccinated for West Nile virus may be vaccinated beginning at 6-8 weeks of age, with two doses of vaccine at 3-6 week intervals.If the mares did receive the vaccine prior to foaling, it is recommended starting at 3-4 months of age.
(2) In low risk areas, foals from vaccinated mares may be started at 5-7 months of age, while foals from non-vaccinated mares can be started at 3-4 months of age.
