Our vet recommends three months for the 1st shots of Tetanus/Flu and WNV ( we live in a high risk area for WNV), followed by the booster 4 - 6 weeks later and then Rabies at 6 months. We start deworming them at about six weeks with Strongid P and then every month there after till after weaning. Been doing this for years and we find it works well. My only suggestion, give those very first shots in the hip rather than the neck, had a foal this year with a huge lump on his neck and could not lift his lift his little head for days. Just a slight reaction, but I hate to see them not able to lift their heads, makes nursing difficult.
