Active immunity typically takes several weeks to develop after exposure to a pathogen or vaccination. This process involves the immune system recognizing the antigen, producing specific antibodies, and generating memory cells for future protection. The exact timeframe can vary depending on the individual and the type of pathogen or vaccine involved. Generally, it can take anywhere from a few days to a few weeks for active immunity to become fully effective.
Active immunity can take time to develop, as the body must first be exposed to a pathogen to generate a response, which may leave individuals vulnerable during this period. Additionally, it may not offer immediate protection in cases of severe infections. Furthermore, active immunity may require booster shots to maintain adequate protection over time, and it can lead to adverse reactions in some individuals. Lastly, not all pathogens elicit a strong active immune response, potentially leaving individuals susceptible to certain diseases.
