2004 APR 7 - (NewsRx.com & NewsRx.net) -- The risk of vaccinia transfer to the hands of vaccinated persons after smallpox immunization is very low if the vaccination site is properly bandaged.
According to published research from the United States, "Transmission of vaccinia virus after smallpox vaccination is a concern. We conducted a prospective examination of the protection afforded by vaccination-site bandages in recently vaccinated individuals. After smallpox vaccination, inoculation sites were covered with two occlusive dressings. Site assessment and bandage changes occurred every 3 to 5 days until the site was healed. At each visit, specimens from the vaccination site, outer dressing surface, and contralateral hand were obtained for vaccinia culture."
"For 148 vaccinated subjects, vaccinia was detected from vaccination lesions of every subject on several occasions," reported Thomas R. Talbot and colleagues at Vanderbilt University. "Only 6 (0.65%) of 918 dressing (95% CI, 0.24%-1.4%) and 2 (0.22%) of 926 hand (95% CI, 0.03%-0.78%) specimens tested positive for vaccinia. The mean number of bandage changes was 9.6 (95% CI, 9.17-10.0). Vaccinia ...
