My girlfriend found out she has shingles. Luckily, she's at her parents place up in WI until Sunday and I don't have any symptoms. So, I'm trying to get revaccinated for chicken pox (last time I was vaccinated was in 1990). I called to ask my parents if I had any side effects after the vaccination, as I was about 4 back then, and they told me I had mild symptoms of the disease. Should I not fly at least for about a day after I get the shot? Is there any legal guideline on this?

Thanks in advance.
