I wonder how many of these "concerned parents" are fully vaccinated themselves. I think it's ridiculous, but hey, if you want your nanny to have certain aspects, then you have the right to ask for them. However, it seems that many parents have unrealistic expectations of nannies. I've seen nannies treated like pets, so this article really bothers me because of that.
This does just seem like another made-up article for pharma though. I can't really imagine it being a real common problem for regular parents. Maybe the rich, New York, "nanny as pet" type families. I think it's great that potential nannies are saying "no." It'll make them think twice about what's more important, a good person to help with your children, or someone who's willing to be your pet.
They should be more concerned with Nanny's hygiene and healthy habits than vaccine status.
