A case of pigmented basal cell carcinoma developing in a smallpox revaccination site is presented. Any progressive change within a smallpox vaccination scar should be thoroughly evaluated and treated appropriately after tissue diagnosis.

Serological response to cholera revaccination has been studied in a semi-closed community consisting of individuals mostly in the 2-20-years age-group. The subjects had been inoculated against cholera every year at the beginning of the local epidemic season. Pre- and post-vaccination sera were obtained from 29 subjects inoculated with cholera vaccine (test group) and 28 from subjects inoculated...

There was an epidemic of small-pox in the Kolar Gold Fields in the late autumn and winter months of 1942. A few sporadic cases had been reported since May 1942, but the disease took an epidemic form towards the end of October. One hundred and thirty-seven cases were admitted into the Epidemic Diseases Hospital during the following three months, November 1942, December 1942 and January 1943. An ...

extending the time for revaccination beyond 10 years may be based on insufficient and conflicting evidence of persistence of immunity (1,2). The evidence that cellmediated immunity and neutralizing antibody persist after one vaccination is conflicting (2–5). This residual immunity is often low, and its protective activity in vivo is unclear. Similarly, in vivo reports of durable immunity to sma...

Background Treatment with Rituximab (RTX) in patients rheumatic diseases (RD) has presented a challenge during the COVID-19 pandemic, as RTX leads to markedly reduced and often undetectable antibody responses after vaccination (1). Objectives To investigate effect of mRNA revaccination (two doses) on response RD who were initial vaccine non-responders. Further, examine if B-cell levels or T-cel...
