Vaccinations?

What do you guys vaccinate for, and when?
We do lots of organized trail rides.
We're bringing in a new mare who is due t foal in August. What do i need to vaccinate the baby and it's mom with at this point? She's coming to us fully vaccinated and health checked.
YE-HA a wee-wittle BABY!!

You'd probably want to vaccinate for East/West., Potomac, Flu, Rabies, Tetanus, WNV, Rhino.....uh I can't think of anything else. I'm not sure about the preggo mare....I'm sure Appy knows.
