Agreed, just depends on the horse. Typically you give the horse the main vaccinations in spring, but any that need boosters (such as Stangles) in fall. I would recommend waiting until spring, but keep a close eye on him for any sign of illness and contact the vet right away. Most horses are fine getting all their vacs all at once, but some have reactions, so just talk to your vet and see what they say.
As for riding in cold weather, you just need to make sure that
A- your horse won't get any snow balled up in his hooves if you ride outside
B- you give EXTRA warm up and cool down time. In that weather, I wouldn't want my horse to sweat, unless you are a dedicated cool downer person, with a wool sheet and the will to walk for an hour if your horse has a full winter coat, but if you clip or your horse doesn't have much of a coat, just be super careful. I would recommend 20 minute warm-up and 30 minute cool-down if your horse just trots for 10 minutes. With that much time warming up/cooling down, it takes up most of your riding time, and to me, it is just worth it just to walk the whole time, as I don't have to put aside half an hour to cool down my horse! I wouldn't ride my horse in conditions under -17 Celsius or 1 degree Fahrenheit, but that is just coastal me where it doesn't go below 4 degrees Celsius or 40 degrees Fahrenheit during winter!
