Smallpox vaccine scar Many people (mostly in their 40s or older) who got the smallpox vaccine have a permanent scar on their arm where they got the injection. This scar isn’t from the needle but rather from the body’s immune reaction to defend itself against the controlled infection caus...
By history, the vaccine site progressed through typical postvaccinia changes, but eventually developed a nodule that was cosmetically bothersome. There was no history of atypical scar formation. On physical examination, there was an 8mm脳8mm, firm, nontender, flesh-colored nodule on the left upper...

scar. Humansmallpoxvirus was one of the most contagious (secondary attack rates ranging from 30% to 80%) and fatal of viral infections. In 1980, the WHO declared that smallpox had been eradicated globally, highlighting the success of massvaccination programswith a highly effective vaccine, ...
36 At some point, vaccinia replaced cowpox as the smallpox “vaccine.” Recent genotypic analysis suggests that vaccine strains of vaccinia virus are most closely related to cowpox viruses from continental Europe.37 A single strain of the virus, derived from the New York City Board of Health (...
The latter had a detectable scar at 28 days and in all probability represents a late take while the former did not have any scar. Thus, only one child (2%) after vaccination with C L vaccine had no antibody or dermal response. DISCUSSION The purpose of this study was to compare ...
No specific vaccine for cowpox is necessary or commonly used. 10 What causes smallpox? Smallpox was caused by the variola virus, affecting only humans. 9 What were the symptoms of smallpox? Symptoms included high fever and a widespread, distinctive rash. 8 How did cowpox contribute to the ...
