Vaccine Design: Vaccine design refers to the process of developing vaccines that can stimulate the immune system to prevent or treat specific diseases. It involves identifying antigens (harmful substances or components of pathogens) that can trigger an immune response in the body. The goal is to create vaccines that are safe, effective, and capable of inducing a robust and long-lasting immune response against targeted diseases.Drug Delivery Technology: Drug delivery technology refers to the methods and systems used to administer therapeutic substances, such as drugs or vaccines, into the body in a controlled manner to achieve the desired therapeutic effect. It involves the design and development of various delivery systems, such as nanoparticles, liposomes, microparticles, patches, implants, and targeted drug delivery systems. These technologies aim to optimize drug release, enhance drug stability, improve bioavailability, and target specific sites in the body, thereby increasing therapeutic efficacy while minimizing side effects.
