After a vaccine is given, it is possible to follow an active immune response by determining the amount of antibody present in a sample of plasma; this is called the antibody titer, after the first exposure to the vaccine, a primer response accrues. For a period of several days, no antibodies are presentand then their concentration rises slowly, and levels off, and gradually declines. The second exposure is called a ''booster'' because it boose the antibody concentration to a high level. The high antibody concentration is expected to help prevent diseases symptoms. if that individual is exposed to disease causing antigen. An active immuniy is dependent on present memory B-cells and possible T- cells that are capable of responding to lower dose of antigen. Active immunity ugally long-lasting, a booster may be required after a certain number of years.
Vaccine are substances that ugally do not cause illness but even so the immune system responds to them. Traditionally vaccines are pathogens themselves, today it is possible to genetically engineer bacteria to mass-produce a protein from pathogens, and this protein can be used as vaccine. This method has produce a vaccine against hepatitis B, a virus-induced disease, and cine against malaria, a prtozonan induce disease. Vaccinations can be very effective in men women and children, and therefore still been study and tested and is used to save
