rubella titer

[GingerSue]

what is considered to be susceptibility/immunity

here in my book, this is what is printed throughout:

HAI test 1:10 indicates immunity

HAI test

If > 1:10 then avoid children who have rubella

Later in the book:

1:18 or greater is evidence of immunity

less than 1:8 is susceptibility to rubella

no wonder I'm a little unsure

anyone know?

or can guide me to a source that's current for clearer information

thanks

and because meruvax II passes to breastmilk, are there any risks to the baby who is breastfeeding?

[Elvish, BSN, DNP, RN, NP]

According to the CDC, AAP and the ACIP, getting the MMR (or rubella) vaccine while breastfeeding is considered safe. There is supposedly a theoretical risk that, since it is a live vax, and it is excreted in breastmilk, then virus could cause illness in the baby. I have personally never seen it happen, and I gave lots of MMR to BF women at the community health center where I used to work.

That said, rubella is generally a mild illness in babies & children. The greatest risk is to a developing fetus.

I wouldn't worry so much about the actual numbers on a rubella titer unless you will need to know them specifically for a test. In the real world, you will get the lab results from lab and there will be a result followed by "rubella antibody detected. [or not detected]" Most people are immune. Some people have gotten the vax but never have an immune response to it & so will still test as non-immune. Some folks are equivocal, meaning their immune response was not strong enough to call it immune, but not weak enough to call it non-immune.

Hope this helps.
