Vaccine Design, Production and Safety
The new era in vaccine designing has changed the old concepts about the discomforts and difficulties of vaccine acceptance to common people. It has increased the safety and efficacy of the vaccines and has made the delivery processes easier. Vaccines are of mainly two types, prophylactic, or therapeutic. The agent of vaccine influences the body's immune system to identify the foreign agent, destroy it, and "remember" it so that the immune system can more easily identify and destroy any of the pathogenic microorganisms in future.
