Question

Quizplus · Accepted Answer

The vaccine described is a subunit vaccine because it only contains fragments of the HIV virus (specifically, the proteins) rather than the entire virus or a weakened/attenuated version of the virus. Additionally, the vaccine is genetically engineered to be made using a eukaryotic cell line, indicating that it does not contain any live virus particles.
