Recently many publications and statements have been circulated throughout the United States alleging that vaccination in the Philippines had not given protection against smallpox. Quotations from annual reports of the Philippine Health Service have been cited by the antivaccinationists showing that more than 50,000 deaths from smallpox have occurred in the Philippines during the last few years. The inference is that these deaths have occurred among the vaccinated. The inference is entirely without foundation, as the direct opposite actually occurred. The deaths are recorded almost entirely among the unvaccinated.
It may be recalled that during the Spanish régime and for some years after the American occupation more than 40,000 deaths from smallpox occurred annually in the Philippines. When systematic, properly controlled vaccination was instituted, the disease disappeared in the wake of the vaccinators. A striking example of this fact is furnished by the mortality statistics for the provinces surrounding Manila.
