Army within the last two years. For example, in many of the cases of fatal vaccination, which I have investigated, or have on record, for several years past, I find that pneumonia and meningitis figure as the chief complicating diseases which have caused death in acting as a secondary, double, or mixed infection with the primary infection of the vaccination, and that these two diseases are the most common complications together with septicemia and lockjaw in all fatal vaccinations. Indeed, the several fatal vaccinations illustrated in this chapter of vaccination horrors prove this point clearly, as most of them show pneumonia or meningitis or both as the fatal complications. For example, in the case of the Waters boy described on page 168, it appears from the autopsy and hospital report in my possession that pneumonia and meningitis were the fatal complications with the vaccination and are set down in these records as the chief causes of death. Likewise, in the case of the English soldier and the English baby on pages 135 and 123, pneumonia appears as the complicating disease and the final cause of death in both cases. Furthermore, in Dr. Howe’s six fatal cases in 1902, described on page 113, one of which is illustrated in Fig. 11, page 110, it was found that severe lung lesions existed in four of these cases involving lobar and broncho-pneumonia and pleurisy. In the eleven cases of fatal vaccination taken from Mr. Loyster’s pamphlet on pages 145 to 159, meningitis figures as the fatal complication in three cases, paralysis in three cases and lockjaw in five cases.
