The re-emergency and persistence of vaccine preventable diseases.

Wednesday, 4th of November 2015

Vaccination is still the most successful method to prevent infectious diseases. The best achievement of immunization programs are the induction of long-term protection against life-threatening consequences of infectious disease. This is obtained by the generation of protective immunity elected by antibodies and antigen specific B and T cells, which lead to protection. Despite global public health successes of vaccines, to date, the only eradicated disease is smallpox. 
There are many challenges that affect efforts by countries that have hampered progresss and cvergae to required levels. 
This study tries to bring up issues that may have contributed to re emergence and continued spread of vaccine preventable diseases in developed as well as developing countries.

Abstract

The introduction of vaccination worldwide dramatically reduced the incidence of pathogenic bacterial and viral diseases. Despite the highly successful vaccination strategies the number of cases among vaccine preventable diseases has increased in the last decade and several of those diseases are still endemic in different countries. Here we discuss some epidemiological aspects and possible arguments that may explain why ancient diseases such as measles polio pertussis diphtheria and tuberculosis are still with us.
