Vaccine Development for New Viruses

Vaccine development for new viruses involves several key steps. First, researchers identify the virus and study its structure to understand how it affects the body. Next, they design a potential vaccine that triggers the immune system to recognize and fight the virus. This vaccine undergoes laboratory testing and several phases of clinical trials to ensure it's safe and effective for humans. After thorough evaluations, if successful, the vaccine receives regulatory approval. Finally, it’s produced and distributed to the public. This process can be expedited in emergencies, as seen during the COVID-19 pandemic, but safety remains a priority.
