IMMUNIZATION AND VACCINES Immunizations, or vaccines as they're also known, safely and effectively use a small amount of a weakened or killed virus or bacteria or bits of lab-made protein that imitate the virus in order to prevent infection by that same virus or bacteria. When you get an immunization, you're injected with a weakened form of (or a fragment of) a disease. This triggers your body's immune response, causing it to either produce antibodies to that particular ailment or induce other processes that enhance immunity. Then, if you're ever again exposed to the actual disease-causing organism, your immune system is prepared to fight the infection. A vaccine will usually prevent the onset of a disease or else reduce its severity. Why Should Someone Get Immunized? The goal of public health is to prevent disease. It's much easier and more cost-effective to prevent a disease than to treat it. That's exactly what immunizations aim to do. Immunizations protect us from serious diseases and also prevent the spread of those diseases to others. Over the years immunizations have thwarted epidemics of once common infectious diseases such as measles, mumps, and whooping cough. And because of immunizations we've seen the near eradication of others, such as polio and smallpox. Some vaccines need to be given only once; others require updates or "boosters" to maintain successful immunization and continued protection against disease. EFFECTS OF VACCINES Vaccines are very effective at preventing disease, but they don't work all the time. Most of the recommended childhood immunizations are 90%-100% effective,. However, they are not completely understood, sometimes a child will not become fully immunized against a disease after receiving a vaccine. This is all the more reason to get children vaccinated. Children in whom the vaccine is 100% effective protect those few who have not been completely immunized -- lessening everyone's chance of exposure to the disease. Even in cases where a vaccine has not given your child 100% immunity, the symptoms if your child is exposed to an infectious disease will still usually be milder than if he or she had not been immunized at all. SIDE EFFECTS OF VAACINES Today, vaccines are considered safe. As with any medication, they can have side effects. In most cases these are usually mild. Most common minor reactions to an immunization are: Soreness or redness around the injection site Low-grade fever ഗൗരി എസ്സ്. പണിക്കർ 10 A സെൻറ് ജോൺസ് മോഡൽ എച്ച്.എസ്.എസ്. നാലാഞ്ചിറ തിരുവനന്തപുരം നോർത്ത് ഉപജില്ല തിരുവനന്തപുരം അക്ഷരവൃക്ഷം പദ്ധതി, 2020 ലേഖനം  സാങ്കേതിക പരിശോധന - Sreejaashok25 തീയ്യതി: 23/ 04/ 2020 >> രചനാവിഭാഗം - ലേഖനം
