Types of Immunity

11.3 Types of Immunity
 
 
Types of Immunity
  • There are two types of immunity; active immunity and passive immunity
  • Immunization is the process of receiving immunity artificially that can protect the individual from certain diseases.
  • Immunization can be done through serum, antiserum, and vaccines.
Active immunity
  • This immunity stays for a long period.
  • There are two types; natural active immunity and artificial active immunity.
Natural active immunity
  • This immunity is obtained when the individual recovers from the disease after the first exposure to the pathogen.
  • Memory cells are able to remember the infection from the first exposure.
  • If the same pathogen infects the body for the second time, the immune system will respond rapidly.
  • The number of antibodies will increase and be produced rapidly to stop the infection.
Artificial active immunity
  • Immunity is acquired by injecting antigens into the body to stimulate lymphocytes to produce antibodies against the antigen.
  • This type of immunity is known as vaccination.
Passive immunity
  • Provide protection on certain diseases for a short period.
  • Antibodies are obtained from the external source and these antibodies will be excreted after a period of time.
  • There are two types of passive immunity; natural passive immunity and artificial passive immunity
Natural passive immunity
  • Obtained by the baby that receives the antibodies through placenta and breastmilk. 
  • Provide full protection to the baby until the immune system of the baby can take over the task.
Artificial passive immunity
  • Obtained through serum injection that contains certain antibodies to destroy the antigens. 
  • This type of immunity provides immediate protection for short period.
