Vaccination is a way of creating immunity to certain diseases by using small amounts of a killed or weakened microorganism that causes the particular disease. Vaccines and antibiotics are amongst the top two inventions of modern medicine which have saved most number of lives. Around the world, many infectious diseases have decreased by more than 99% in magnitude, primarily because of vaccines. Vaccines are the main reasons because of which polio, tetanus, measles etc have been virtually eliminated from the developed countries.
Although vaccines are available in Pakistan, and many are available free of cost from the government, the coverage of these vaccines in the community is quite low. According to some estimates, only about half of Pakistani children are properly vaccinated, making the other half vulnerable to infectious diseases which have been eliminated in the developed countries. It is the parents' responsibility to make sure that their children are completely vaccinated and on time. At least the free vaccines must be given to all children, and parents should consider giving the paid vaccines to children as well, if they can afford them.
