Answer:
Prevention, some of the BCG vaccines it may provide for the development of childhood tuberculosis (TB), may be indirectly indicated by the subsequent growth of the BCG immune response. The objectives of the study were to evaluate the efficacy and potential difference in post-vaccination response to lyophilized BCG in different age groups and to evaluate its protection against TB over a ten-year period.
Step-by-step explanation:
We have studied the reaction of PPD skin after vaccination and the formation of scars at three different school levels, corresponding to 6, 12 and 15 years, vaccinated with the BCG lyophilized vaccine (Pasteur Institute), currently used in our country. During the 10-year follow-up TB cases reported to vaccinated and unvaccinated adolescents up to 24 years of age were analyzed and compared with the number of cases detected in adults in two neighboring areas (vaccinated and unvaccinated).
