Can the shingles vaccine be contagious to others?

When the blisters are open, with weeping, they are contagious, just like the chicken pox. It is extremely important to stay away from elderly people, infants and small children, pregnant women, and anyone who has never had the chicken pox while the shingles are in their contagious stage. Once the shingles have scabbed over, you are less likely to pass it on.
