Too much to ask?

After talking with my husband & researching, we've discussed making sure everyone who comes to visit us and baby during the first 3 months is up to date on their TDaP vaccine. Mentioning it to my mother on the other hand made her very defensive over getting it. Am I really asking too much for a simple vaccine? We live 14 hours away from home, so it's not like we'll be getting a ton of visitors.
