Injections Diseases and Public Health

Description

The infectious disease public health infrastructure, which carries out disease surveillance at the Federal, State, and local levels, is an essential tool in the fight against newly emerging and reemerging infectious diseases. Immunization is a global health and development success story, saving millions of lives every year. Vaccines reduce risks of getting a disease by working with your body’s natural defences to build protection. When you get a vaccine, your immune system responds. Vaccines are available for these 17 dangerous or deadly diseases. Over the years, these vaccines have prevented countless cases of disease and saved millions of lives. Infants, children, adolescents, teens and adults need different vaccinations, depending on their age, location, job, lifestyle, travel schedule, health conditions or previous vaccinations. Vaccines are among the most cost-effective clinical preventive services and are a core component of any preventive services package. Childhood immunization programs provide a very high return on investment. Vaccination against a range of bacterial and viral diseases is an integral part of communicable disease control world-wide. Vaccination against a specific disease not only reduces the incidence of that disease, it reduces the social and economic burden of the disease on communities. Very high immunisation coverage can lead to complete blocking of transmission for many vaccine preventable diseases (VPDs). The world-wide eradication of smallpox and the near eradication of polio from many countries provide excellent examples of the role of immunisation in disease control. This book is describes briefly some of the major past achievements of vaccination, the present situation in relation to the global use of vaccines and some of the ways in which vaccination could contribute to global health in the future.
