Seroprotection

Seroprotection refers to the presence of enough levels of protective antibodies in the bloodstream to defend against specific infections. After vaccination or natural infection, the immune system produces these antibodies. When antibody levels reach a certain threshold, a person is considered seroprotected, meaning they are likely to be protected from illness if exposed to the pathogen. This concept helps assess the effectiveness of vaccines and understanding immunity within populations, guiding public health strategies for disease prevention.
