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?

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 into the body, to which the immune system responds quickly, creating antibodies 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.
