You can get pregnant after having shingles.
You can become pregnant if you have shingles.
Do you mean shingles? Your question isn't clear. If you do mean shingles the virus can be passed on by direct contact with fluid from the shingles blisters, until they dry up and crust over. If your sister is pregnant then you or anyone else who have shingles should avoid contact with her as she would be at risk of catching shingles.
At least a few months
A person with shingles needs to take precautions around a pregnant woman without evidence of immunity to chicken pox. The pregnant woman should discuss the matter with her health care provider, who may have checked immunity at the preconception visit or a prenatal visit. Because typical shingles is communicable only by direct contact with lesions, even health care workers with typical shingles (not severe) are allowed to work as long as the sores can be covered.
I've heard that you should not be around children or pregnant women for 4 weeks after receiving the shingles vaccine - is that true?
Shingles is not contagious -- it can't be "caught" from someone else. People with shingles can give you chickenpox if you haven't had it. See related link below for information on transmitting shingles
NO!! Please stay away from the patient!!
No. Shingles is not contagious, but someone with shingles can give chicken pox or varicella to someone who has not had chicken pox before.

No. You only get shingles's if you have had chickenpox. No chickenpox no shingles's.
Shingles vaccine protects you from the shingles for few years only.
You could get the vaccine if you already had shingles; but it may not help you from recurrence of zoster, which by the way is less than 5%. If it does recur, the vaccine may help you.
