Immunization
Immunization
Immunization: Immunization is stimulating the body to produce antibodies by artificial means. These antibodies fight against infections later. We can immunized against certain diseases by taking vaccines for them. A vaccine is a preparation of weakened-infectious agents or their products that can be injected or given orally to prevent specific diseases. Vaccines help in the specific prevention of diseases. Today there are many types of vaccines available to prevent infectious diseases. Nowadays, vaccines are available against tetanus, diphtheria, whooping cough, polio, chickenpox, measles, mumps, typhoid, tuberculosis, hepatitis and many other diseases. Many of these vaccines are given to children under the public health programme of childhood immunization.
Pulse polio programme: The pulse polio programme is an immunization drive against polio. Polio is a disease of the muscles and nerves which can cause paralysis. To prevent polio, oral vaccines are given periodically to all children under 5 years of age in our country. This is an effort to eradicate polio, so no child will be infected by the polio virus.
Smallpox vaccine: An immunization programme was carried out earlier to eradicate smallpox. Earlier, in smallpox epidemics people were afraid of going near someone suffering from it. Smallpox was controlled and eradicated with the help of a vaccine.
Making of first vaccine:
An English physician, Edward Jenner (1749—1823) observed that people who got cowpox , a mild disease, did not suffer from smallpox, a more severe disease. Usually, the girls who milked cows got cowpox, a disease that causes rashes on the hands. Jenner decided to test his observations about cowpox and smallpox. Jenner took some pus with a sterile needle from Jenner took some pus with a sterile needle from the cowpox rashes of an infected girl and injected it into scratches made in the skin of an uninfected boy, who soon got cowpox. After he recovered, Jenner injected the boy’s arm with pus from the spots of a person suffering from smallpox. Luckily, the boy did not get smallpox and Jenner’s experiment was successful. The modern term vaccination’ comes from the Latin words 'vacca' which means cow and vaccinia’ which means cowpox. It tells us how Jenner made the first vaccine against smallpox using the microbes of cowpox, a similar but less severe disease.
