my sympathies on your child's battle with a compromised immune system. i'm sure he's in the prayers of everyone who read your slate column

that said, the day care centers, schools, workplaces, and public malls of america cannot be regimented for your convenience. (full disclosure - BA is secular, and has no personal or religious opposition to vaccinations)

the obvious solution is to care for sick child at home, rather than expect this care to be provided by a public access day care center. if your child's health and safety is paramount, wouldn't your decision to take on the role of full time caregiver be a profoundly demonstrative choice?

requiring every citizen to be vaccinated for the disease du jour may put your mind at ease ,but it will be a false panacea. hundreds of people actually die each year from the unfortunate genetic inheritance THEY carry - undetected sensitivity to a random vaccine or medicine.

the solution lies not with the inconvenience and risk to others, but with doing the right thing for your own child, rather than selecting day care so you can enjoy a full time career.
