Brief Answer:
No it is not dangerous.

Detailed Answer:
Hi,

Thanks for writing to us about it.

I can understand your concern, though.

If her IgM test is negative for rubella and her IgG test is > 500 it means she is immune to rubella and she is not infected.

Thus, please do not worry about it, it is not dangerous.

Hope it is useful, feel free to ask more.

Good luck.
