A vaccines helps because they put some of the disease in your body then your body can get use to it so if you get that disease your body can easily fight it out of you!
IT is prepared by weakening or killing a germ of that disease which is not strong enough to cause a disease. vaccines are given through a needle. these causes antibodies in the body's immune system which protect the body from diseases.
Vaccines only protect for one disease.
Antigens do not protect the body from disease. Antibodies protect the body from many diseases.
Because it helps to prevent certain diseases to immunize our body
Side effects are generally mild, and occur sparingly. The diseases the vaccines PROTECT against, however, can leave people crippled, seriously ill, or can kill (but in a horrible, painful way). Believe me when I say, the vaccines are far better than the diseases they protect against, even if there are side effects.
The term "immunisation" refers to the use of immunoglobulins and vaccines in order to protect people from infectious diseases. Vaccines contain minute amount of inactive infectious organisms whereas immunoglobulins contain antibodies.
No. Vaccines are not used for treatment. They are used as prevention.
Simply put there are to many diseases. Some of the existing vaccines, pneumovax for example,only protect against a certain bacteria, and the flu vaccine is redeveloped each year to protect against the strain that is predicted to be the most prevalent. Others, like shingles vaccine protect against the disease, do NOT guarantee immunity but help to lessen the severity and pain associated with the disease.
Vaccines don't kill viruses or diseases; they prevent disease before you are infected.
Vaccines prevent diseases, medications treat them.
Currently, all vaccines on the market today only exist for diseases caused by viruses- though not all diseases caused by viruses have a corresponding vaccine. Notably, the common cold (rhinoviruses) and AIDS (HIV) have no vaccines.
your body has white blood cells which are built up into a immune system these fight the diseases and vaccines boost the system.
