So sorry to hear that! Now I'm totally freaked my daughter just got that shot! Quoting: closing eyes
Don't know much about homeopathics, but there are some that "undo" the harmful effects of vaccines and are vaccine specific and also some can be custom made. Problem is finding a really really good homeopathic physician who is very sensitive to what should be used and when. Some medicines really should not be given until other things have cleared. Sorry, I don't know much about this.
There are foods, herbs that help support health. In general, keep her diet healthy, no artificial sweeteners.
There are nonallopathic (so far) sources of health care.
And if you have a church that does healing prayer or are involved with a spiritual healing system, those are options.
For now, build your belief and hers that she will remain unaffected adversely by this vaccine. The more fear you can eradicate, the better. There are also 24 hour prayer lines, including Unity.
There's lots I could say, but don't know about you enough and not appropriate for here, and way too long. Just don't panic. Explore support options.
