1=> Malaria is caused by a one-celled parasite called a Plasmodium. Female Anophelesmosquitoes pick up the parasite from infected people when they bite to obtain blood needed to nurture their eggs. Inside the mosquito the parasites reproduce and develop.
2=> Immunization =>Immunization is the process whereby a person is madeimmune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease.
Immunity =>In biology, immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune diseases.
Vaccination =>Vaccination is the administration of antigenicmaterial (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccinescan prevent or ameliorate infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. The effectiveness of vaccination has been widely studied and verified.Vaccination is the most effective method of preventing infectious diseases;widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the elimination of diseases such as polio, measles, and tetanus from much of the world.
Vaccine => A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically 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. The agent stimulates the body's immune systemto recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic (example: to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen), or therapeutic (e.g., vaccines against cancer are being investigated).
3=> On May 14, 1796, Jenner took fluid from a cowpox blister and scratched it into the skin of James Phipps, an eight-year-old boy. A single blister rose up on the spot, but James soon recovered. On July 1, Jennerinoculated the boy again, this time with smallpox matter, and no diseasedeveloped. The vaccine was a success.
4=>Limitations are :
1) Person should be bedridden till he/she is fully recovered.
2) The person should be kept isolated from others as the infectious disease spread rapidly.
3) And as once the person body is infected by infectious disease then the person that body parts may not work properly
5=>The basis of Principle of Immunization
By providing vaccination, we can .fool the immune system into developing a memory for a particular infection by putting something, that mimics the microbe we want to vaccinate against, into the body. This does not actually cause the disease but this would prevent any subsequent exposure to the infecting microbe from turning into actual disease.
