False. There is a lag time between infection and protection. During this time, the immune system responds and provides protection against the infection.
Step-by-step explanation:
False. There is a lag time between infection and protection. This lag time is the duration it takes for the immune system to respond to the infection and provide protection. During this lag period, the virus or bacteria may continue to multiply and cause the development of the disease. Once the immune response catches up, it can prevent the further progression of the disease.
