Vaccines are among the most impactful public health
innovations in human history, yet questions about their
development, effectiveness, and safety remain widely
discussed. This lecture explores the scientific foundations of
vaccines, tracing their research and invention from early
immunization practices to modern technologies such as mRNA platforms. Attendees
will gain insight into how vaccines are designed, tested, approved, and continuously
monitored for safety. The lecture will also address common concerns and
misconceptions, explain how risks are evaluated and minimized, and highlight the role
vaccines play in preventing disease and protecting communities. By examining both
the science and the safety systems behind vaccines, this talk aims to provide a clear,
evidence-based understanding of how vaccines work and why they remain a
cornerstone of modern medicine.
