bf + immunity

[chibi]

i have been vaccinated against measles (as a child). If I am still bf my dd (nearly 9 mo) is this immunity conferred on her too until I stop bf?

TIA

.

the thing about vaccines is that

A. they diminish in your system over time.

B. its effectiveness also depends on the the % of vaccinated people in your local environment.

hence why public health types worry about it dropping below a certain percentage in the population. I can't remember the number but at somewhere below more or less than 80% of vaccinated the population, it is likely that an epidemic can break out and hence people where the vaccine have worn off also become at risk.

there may be more reasons but those are the 2 i know about.

this is why i was worried. i live in an area where vaccination rates are low.

chibi, I agree with kiskidee about the vaccinations - if you're in an area with low measles vaccination rates then there is the risk of an epidemic breaking out (because there are lots of people vulnerable to the illness) and although you were vaccinated you won't know whether the vaccine was sucessful in you (there is a failure rate, don't know what it is for measles /MMR though), or whether your initial immunity has waned over time.

Your daughter will get some protection through your BM if you have some level of immunity from your vaccination, as she gets antibodies from you in your BM. If I remember right, it should be enough to help her out in the first stages of an infection until she can start fighting an infection on her own, ie producing her own antibodies.
