The phase in which killer t cells strike at foreign cells and at cells of the body that have been invaded and infected is called the attack phase or the phase 3. It is the part where killer T cells would strike the foreign cells and the body cells that were infected and invaded. They would puncture the cell membrane of the cells, sacrificing the body cells to destroy the invaders from within. This action is called as cell-mediated immune response since the attack is done by the cells. T cells would also trigger inflammatory response and would recruit macrophages to aid in the cleaning of the site.

In the immune response, the phase in which killer cells attack foreign cells and in body cells that have been attacked and infected is called passive immunity

Further explanation

Passive immunity is an immunization that occurs when the body gains immunity by injecting serum into the body that contains antibodies to disease. This immunization is usually given when in an emergency where there is not enough time to produce antibodies to fight antigens that enter the body. For example, when a person is bitten by a snake, he will be given an antibacterial serum.

Active immunization is a condition of the body that can form its own immunity by entering the vaccine into the body so that the vaccine will stimulate the production of antibodies themselves. for example the polio vaccine, the polio vaccine is a weakened poliovirus, when it enters the body, it makes the body have more immunity so that when it attacks polio, the body can fight it.

From the two definitions above we can find out the difference between active and passive immunization, especially when viewed in terms of the time of administration and the vaccine given. If immunization is active when immunization has been determined such as polio immunization when the baby is old and other vaccines have been given the recommended time. Usually, vaccines given in active immunization are vaccines that should be given as infants, and even the government itself recommends giving vaccines.
