Vaccines are given as part of a national vaccine program determined by the competent health authority in each country, and vary in the details of the timing of the doses from one country to another and may also vary within the country from one doctor to another! But it is in line with the recommendations of the World Health Organization and with the recommendations of the global authority on disease control. There are oral vaccines such as oral paralysis and rotavirus vaccines, as well as vaccines given as intramuscular injections such as triglycerides, jaundice, and others given as subcutaneous injections such as measles, spinal meningitis, and so on.
