Vaccination is the process of administration of antigen(vaccine) which stimulate body’s immune system to develop acquired immunity.
Immunity defense the body against infections caused by microorganisms. Also Immunity is classified into two types such as Natural Immunity and Acquired Immunity.
Body contains natural immune components like Intact Skin, Salivary Enzymes, and Neutrophils, Natural Killer Cells, Which provide Natural Immunity against infection prior to exposure to a Pathogen or Antigen.
Acquired immunity is that which develops antibodies (resistance against infections) after an attack of an infectious disease or by a pregnant mother passing through the placenta to a fetus or by vaccination.
Vaccination is the process of administration of vaccine. A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. Vaccination provide immunity for eradication of smallpox and the prevent the spread of diseases such as polio, measles, and tetanus. The World Health Organization (WHO) reports that licensed vaccines are currently available for twenty-five different preventable infections.
Vaccination given during childhood is generally safe. Some common side effects include fever, pain around the injection site, and muscle aches. Your child’s immune system responds to the antigens in the vaccine by making antibodies to fight the germs and memory cells to remember the germs in case they encounter them in the future. Vaccinations are given by Oral Drops and Injections (needles), usually into the Child’s Upper Arm or Leg.
Some vaccines for children need a series of doses (usually 2 to 4 doses) to reach their full effectiveness. This is called a “primary series”. Booster dose is given for some vaccines after primary doses to refresh the immune system’s memory. If your child misses a vaccine dose, they’ll need “catch-up” doses (also called “supplemental” doses) to ensure that they are protected. Your child may also need a catch-up dose if a new vaccine becomes available after your child has already passed the age.
