Egg-based vaccine production

Egg-based vaccine production involves using chicken eggs to grow viruses that cause diseases, such as influenza. Scientists inject a small amount of the virus into healthy eggs, where it multiplies. After a few days, the virus is harvested from the eggs. The harvested virus is then killed or weakened to create the vaccine. This process allows the immune system to learn to recognize the virus without causing disease, providing protection when exposed to the real virus in the future. This method has been used for decades and is known for its effectiveness in vaccine development.
