This is called active immunity.
Active immunity<span> results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Exposure to the disease organism can occur through infection with the actual disease</span>, or introduction of a killed or weakened form of the disease organism through vaccination<span>.

Active immunity is long lasting, potentially even life-long.</span>
