My concern is that my sister fully vaccinates. My niece hasn't had her vaccinations since my DD was born, but in September she will get her 12 month vaccinations and my nephew will have his in October. I know vaccines shed, but I don't know for how long. We don't have anywhere we can stay for however long shedding would last.
What can we do at home to lessen my DD's chances of catching something from my niece and nephew?
