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 system to 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).

Vaccine➫ A substance containing a harmless form of the germs that cause a particular disease.
Ex:- SmallPox
Vaccination➫ Antigenic material to stimulate an individual's immune system to develop adaptive immunity to a pathogen.
♦ It can prevent or ameliorate infectious disease.
♦ It is a biological preparation that improves immunity to a particular disease.
♦ The acellular vaccine uses selected antigens of the pertussis pathogen to induce immunity.
➧ Types 0f Vaccines are:-

❱ Live-attenuated vaccines
❱ Inactivated vaccines
❱ Toxoid vaccines
❱ Subunit, Recombinant, Polysaccharide & Conjugate vaccines.
➧ Benefits 0f Vaccines are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵
❱ It helps to prevent disabilities like - blindness & paralysis.
❱ It protects children from serious illness & complications of vaccines preventable diseases.
❱ They prevent diseases that can be dangerous or even deadly.
❱ They prepare the body to fight disease without exposing it to disease symptoms.
➧ How does Vaccines works:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵
A vaccine works by training the immune system to recognize & combat pathogens - viruses or bacteria.
To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
These molecules are called antigens
➧ The most common and serious vaccine preventable disease tracked by the World Health Organization are:-

❱ Diphtheria
❱ Measles
❱ Mumps
❱ Rubella
❱ Tetanus
❱ Hepatitis B
❱ Mertussis
❱ Meningitis
❱ Tuberculosis
❱ Yellow Fever
❱ Poliomyelitis
