Can contact with a chickenpox sufferer make a person who has had shingles once to have a seond case of shingle

Few people that have a good immune system suffer further attacks, but those that have a weakened immune system may suffer repeated attacks, ie., in immune competent patients Shingles only occurs once in their lives, so keeping the immune system healthy will help prevent reoccurrence. On reflection, I guess that until the danger is past, nobody really knows how good their immune system is; there's always the chance that it could develop. The second website states: 'The incidence of shingles rises with increasing age. More than 50 percent of cases occur in people over 60. Older people may also lack exposure to children with chickenpox, thereby losing an opportunity to boost immunity and prevent virus reactivation. Although most people have only one attack of shingles, about 4 percent will have further attacks.'
