It’s also a good idea to space the vaccinations out so you don’t give the foal everything at the same time.
For example…
Eastern/Western/Tetanus 1st shot
Flu/rhino 1st shot
2 weeks later
Potomac Fever 1st shot
West Nile 1st shot
2 weeks later
Eastern/Western/Tet 2nd shot
Flu/rhino 2nd shot
2 weeks later
Potomac Fever 2nd shot
West Nile 2nd shot
Every vaccination causes an inflammatory response in the foal’s immune system and that’s why I think it’s important to give them some recovery time in between shots.
I don’t vaccinate for Strangles or Botulism because I don’t have it here and don’t feed round bales, but you should know what you give to your adults and just copy that for the foals.
I wait until the foals are 6 months old before I start vaccinating, and yes, it’s IM in the neck muscle…
Good luck!
