Prevention of the disease is the key to public health. It is general saying that “prevention is always better than cures”. Vaccine prevents the disease in the people who receive them and protect them who come into the contact with the people who are not vaccinated. Vaccines also help preventing the infectious disease those are once common in the country. Such disease include polio, pertussis (whooping cough), diphtheria, measles, rubbela (German measles), mumps, Haemophilus influenza type b (Hib) and tetanus.
Parents are constantly concerned about the health and safety of their children and take many steps to protect them. These steps range from child-proof door latches to child safety seats. In the same way, vaccines work to protect infants, children, and adults from illnesses and death caused by infectious diseases. While the U.S. currently has record, or near record, low cases of vaccine-preventable diseases, the viruses and bacteria that cause them still exist. Even diseases that have been eliminated in this country, such as polio, are only a plane ride away. Polio, and other infectious diseases, can be passed on to people who are not protected by vaccines.
Parents are constantly concerned about the health and safety of their children and therefore they take many steps that can prevent the child and work as a shield to the diseases. The best option comes here is the vaccination. Vaccine works to protect infants, children and even adults from illnesses and death caused by many infections diseases. In some advanced countries like US and UK, many of the disease are eliminated by strictly following the immune schedule (vaccination) as advised by the WHO.
Another benefit to get vaccination is cost. The cost compare to curing the actual disease will be much more as compare to the cost of the same disease for vaccination. For instance, if you get the typhoid vaccination; the cost will be much lesser than the cost of treating the typhoid once your child is actually infected by typhoid. Hospitalization, medicines and injections will be very costly to treat the typhoid and the vaccination is available with very low cost. 
Vaccination has its own time, period and schedule. According to the age, weight and progress of the milestones of the baby, the vaccine schedule can be altered but not much. The dosage of vaccination remains same among babies but may be different for adults.
The vaccination schedule is announced by World Health Organization. It is mandatory to follow that if you need healthy baby and healthy society. Many of the local governments now offer free and low cost vaccinations in their regions. For instance, polio drops are available free almost everywhere in the world.
Here is the general schedule for vaccination that is recommended by health organizations.
