Which vaccines may shed?
I am doing some delayed vaccination with my son due to family history of vaccine reactions and his eczema/risk of asthma issues.
I am also babysitting a younger infant who is being vaccinated on schedule (my son is 6 months and the other baby is 10 weeks). She had a fever from her 2 month shots so her parents kept her home a few days. But it made me wonder - is my son at risk of catching something from her?
Thus far we have done both doses of rotavirus vaccine and 2 shots each of DTaP and Prevnar (based on my pediatrician's assessment of what illnesses are prevalent in our area - she is recommended by the local crunchy moms group as being one of the peds open to varied schedules here). We have not done HepB, HIB, or IPV (considering skipping HIB altogether but I'm not sure about that), doing HepB in pre-adolescence, IPV at some point before traveling anywhere. We most particularly want to delay MMR since that is the one my husband had a terrible reaction to as a baby (his ped told his mother to delay MMR for him and for her second child), and may do varicella as a pre-teen if he hasn't caught it naturally before that. I am totally undecided about the flu vaccine, though I lean towards it being too ineffective to be worth it. And I haven't looked into HepA yet.
So, I have the 6 month well baby check coming up next week. Does the presence of another baby in my home a few hours a week change my risk calculus at all? My baby is EBF, though we are starting to add a few solids here and there. Aside from this new baby I'm watching he is pretty isolated from other children. We only leave the house once a week.
