Vaccine - a key part of modern medicine.That vaccination mankind owes to the fact that many diseases, because of which died out once the entire country today were in the distant past.Thanks to vaccination, modern man finds virus smallpox or plague only from books and medical journals.Some vaccinated against the most common diseases a person receives at birth, according to the corresponding calendar. vaccination history began in the XVIII century, when British scientist Edward Jenner invented the world's first vaccine against smallpox. Among the many vaccines that we put in a lifetime, there are different types of drugs.Most often, the doctor puts the patient a vaccine or therapeutic serum.Despite the fact that the vaccine, and therapeutic serum are methods of preventing infection between them there are significant differences.

What is a vaccine?

first in the history of medicine, the vaccine was created in the XVIII century.Edward Jenner, a British scientist, produced a vaccine against smallpox, using vaccinia virus, recovered from the body of sick animals.Cowpox is not dangerous to humans, but has contributed to the development of specific antibodies that protect people from the disease.Because of the vaccine Jenner, smallpox incidence began to decline.The next stage in the history of vaccine prophylaxis is associated with the name of the famous scientist Louis Pasteur.He went on to study Jenner and began to create vaccines based on attenuated microorganisms.

Thus, the vaccine - a bacteria or their toxins, previously weakened or killed so as not to harm the human body.Vaccines stimulate the body's defenses, contribute to the development and adaptation of its own antibodies of the immune system to certain types of pathogens.

What is whey?

If the response to the vaccine body begins to produce antibodies on their own, the therapeutic serum is a set of ready-made antibodies.After the introduction of serum does not require additional time to form a full immunity.Often injected with serum do in case of direct infection when the preventive measures are taken too late.
example of a rapid-acting whey is inoculated against tetanus.Tetanus toxoid administered immediately after injury to the skin, to prevent the development of disease in the event of contamination.

and vaccines and serums administered by injection.It is believed that the serum from the vaccine differs by the fact that it is less likely to cause allergic reactions in a patient.However, the physician should carefully examine the condition of the patient prior to administration of the drug and to comply with all the rules in order to avoid possible complications.
