Vaccination is a means of securing the lives of millions of people from disease. The last week of April every year is celebrated as World Immunization Week, which aims to make people aware of the collective action of immunization and its awareness. Programs like universal immunization, Mission Indradhanush are run in India to protect against diseases. Amid the growing coronavirus infection, scientists from all over the world are engaged in the preparation of the vaccine. The theme of World Immunization Week is an immunization for vaccine work for all, i.e., The World Health Organization aims to spread awareness among the people that all health workers from developing vaccines and making the vaccination campaign success are like heroes.
It is not that for the first time, a virus has spread panic. Earlier, epidemics like Spanish flu, swine flu, SARS, plague have spread. After research many diseases, scientists have prepared anti-dots and vaccines that fight them. Smallpox and polio were also a major epidemic, but now the effective vaccine for these diseases has been prepared. These have been curbed since vaccination at the universal level. Through immunization, people have been rescued from many epidemics. You may be surprised to know where the word vaccination came from! In fact, the word is made up of Latin-language vaccines, which means cow or related to it. The vaccine could be invented only after use on women working in the dairy industry. In the 18th century, France's great microbiologist Louis Pasteur gave the germ theory of disease, and on the same foundation, he developed vaccines of Chickenpox, Cholera, Rabies, and Anthrax.
In the year 1798, British physician Edward Jenner developed a chickenpox vaccine. In fact, during the research on women working in the dairy industry, women working there were infected with cowpox, but they did not have smallpox. To prove this, in the year 1796, he made an incision in the hand of a 13-year-old teenager and infected him with cowpox, he found that he did not have smallpox. After confirming this, he made a vaccine for smallpox. Their efforts succeeded in rescuing the victims of the disease.
Do you know how a vaccination works! In fact, humans, who are prone to viral diseases, are called antigens. To fight antigens, the human body creates a certain type of protein called antibodies. In the beginning, the speed of the formation of antibodies in the body is low. The rate of antibodies in the human body and the speed of reproduction of the pathogen is victorious. As compared to the pathogen, antibodies in the human body are not sick in case of becoming more. Immunization is done only to develop antibodies in the body. In fact, the vaccine works to activate the natural defense system of the human body. When an external disease tries to enter the body, the vaccine fights it. Most vaccines are ready to deal with virus-borne diseases.
