Immunizations also called vaccines are drugs used to prevent certain forms of diseases and infections, as defined by Kids Health.org, a website supported by the National Institutes of Health. Immunizations are usually given during the early years of childhood, some infants as young as a few days old are already given vaccines in some parts of the world. Most vaccines are made using a very small and controlled amount of the bacteria that it targets. This weakened microorganism stimulates the body to form antigens and antibodies for specific for that disease. Commonly, vaccines are injected into the body, but some are taken orally. Vaccines are also given at pre-determined doses and schedules, a few are just given once, but most of them are given more than 2 times.
Vaccines do not guarantee 100% protection and disease prevention. Many factors contribute to this. A person may not form enough antibodies against the bacteria or his system might not react to the immunization given. Some of the diseases that already have vaccines and immunizations include the Pulmonary Tuberculosis, Measles, Chicken Pox, Poliomyelitis, Hepatitis A, Hepatitis B, Mumps, Tetanus and Rabies. Newborn babies are temporarily immune to diseases because of the antibodies they get from the placenta and breast milk but as they grow older, this immunity fades away. The American Academy of Pediatricians or AAP has a recommended vaccination schedule for children who belong to different age groups.
1) Hepatitis B Vaccine – Given to prevent Hepatitis B infection in the liver which can potentially lead to liver cirrhosis and cancer. This vaccine is given in 3 doses. The first dose can be given as early as 12 hours after birth. The second dose is introduced 1 to 2 months after the first and the third dose will follow after 6 to 18 months after. The immunity this vaccine provides is long term and can last up to adulthood.
2) Pneumococcal Vaccine – Immunization against pneumonia, bacterial meningitis and blood infections. Pneumococcal Vaccine or PCV is given in 4 doses. The first dose is given when the baby is 2 months old. The second dose is given during the fourth month. The third dose follows at the sixth month and the last one is given at the twelfth month. After giving the vaccine, the child might experience a slight fever and soreness in the injection site.
3) DTaP – The DTaP vaccine provides immunity for 3 diseases namely diphtheria, a serious throat infection, tetanus, a nerve disease and pertussis or whooping cough. DTaP is given in 5 doses. Usually introduces at the 2nd month, 4th month, 6th month, 15th month and 6th to 8th year of life respectively. Booster doses needs to be given for tetanus every 10 years.
4) Inactivated Polio Virus or (IPV) – The IPV vaccine provides immunity for poliomyelitis, a debilitating viral infection. Usually given at the 2nd, 4th, 6th month and during ages 4 to 6. IPV vaccine is one of the few vaccines that can be given orally. The IPV vaccine provides permanent protection against polio.
