Toddlers, infants, and youngsters almost every child is given vaccine in the form of shots to treat various infections. But many vaccines do not require the use of injections as they can be taken easily by mouth e.g. Polio Vaccine. To fight and to boost the Immune system adults also receive immunization through different sources. In this article we will see, how vaccines help us to boost our immunity to fight diseases? Why some vaccines are necessary in the stage of childhood and Diseases that can be prevented through vaccines?
MECHANISM OF VACCINES: Vaccines or Immunization works by creating a protective layer against the infectious microorganism that has triggered any damage to the immune system. When the body is affected by any infection, the vaccine in that case works best to fight the infection and to boost the immune system. In this process a harmless germ is injected in the body, to which the immune system responds quickly, creating anti-bodies to encounter the foreign substances. Therefore a memory is formed which the immune system can easily save and recognize, neutralize and attack the foreign substances when they attack again.
TIMING OF VACCINES: According to (WHO) World Health Organization, the polio vaccines should be given at the time of birth. In order to develop complete immunity against microorganism one should take several doses of vaccines. This helps in strengthening the immune system. Hepatitis B vaccine and BCG vaccine for childhood tuberculosis are given at the time of birth specifically in countries where theses disease occurs commonly.
