mRNA Vaccines (Pfizer-BioNTech & Moderna, 2020): The rapid development of mRNA vaccines for COVID-19 marked a historic biotech milestone. Unlike traditional vaccines, mRNA vaccines deliver genetic instructions to cells to produce viral proteins, triggering an immune response. This platform is highly adaptable, enabling swift responses to new variants and pathogens. Clinical trials showed over 90% efficacy with strong safety profiles. The success of these vaccines validated decades of research and opened doors for mRNA-based treatments for cancer, HIV, and genetic diseases. Manufacturing is scalable and faster than conventional methods. This breakthrough not only helped end a global pandemic but also established a new paradigm in vaccinology and therapeutic development.
