Abstract
Through this experiment an observation was made on the changing blood pictures of forty healthy male-employees at the Tokyo First National Hospital who were given Influenza A '57 vaccination.
Before vaccination and 48 hours and 10 days after vaccination, the W. B. C. was found to be unchanged. Both monocytes and eosinophils slightly increased in number while neutrophils decreased slightly. No apparent change in number of lymphocytes was noted. However, atypical lymphocytes was found in 29 cases out of 39 but this phenomenon showed no relationship with either increase or decrease in number of lymphocytes.
No significant relationship was noticed among the following three factors: number of lymphocytes, atypical lymphocytes, and hemoagultinating inhibition antibody.
