Vaccines are absolutely safe and very effective for preventing many childhood diseases. Although the vaccines cause some pain and discomfort to the children during administration but this minimal pain or tenderness where it has been injected should be born to protect the child from a disease that could take its life or impair it for life. Sometimes the child could suffer from serious side effect like allergies, but that rarely happens and the disease prevention benefits of getting vaccines are much greater than probably side effects. Vaccination protects children when their bodies are not fully capable of fighting any disease-carrying viruses.
Regrettably, some babies cannot receive the vaccines because of being too weak or being susceptible to allergies. In such cases, it is quite risky to inject the child with any vaccine because at that stage it might do more harm than good. Other than that, parents should have the other children vaccinated and should also take preventive measures to avoid them being struck down by the same disease that they are trying to immunize their children against. Although childhood diseases do not occur a second time, there are always the rare exceptions when adults can be infected by these diseases
Vaccinations save the family both time and money because a child that has not been vaccinated against a preventable disease might be refused admittance at a school or a child care facility. Some diseases that can be easily prevented by vaccination will take a lot of money in medical bills and time off from work for parents in case they cannot afford help to care for the child. Vaccination is mostly free in government clinics and parents should make the time and exert the effort to get their children vaccinated to prevent themselves from greater losses
Vaccinations also protect future generations because once a child has been vaccinated properly, he might be immune from many diseases for his entire life and because of his good health, will probably have very healthy children who might have gained immunity from their parents. However, no matter how healthy a child might seem to be, it is prudent to have the child vaccinated and not take any undue chances with the life and health of the child. Before vaccines were invented by scientists, the mortality rate among children was quite high. Vaccines have eliminated childhood diseases in most parts of the world, but there is always the possibility of recurrence by a stronger virus that can again threaten the health of children.
