Which type of vaccine could possibly cause a person to develop the disease? which type of vaccine could possibly cause a person to develop the disease? toxoid vaccine inactivated killed vaccine attenuated live vaccine toxoid vaccine and inactivated killed vaccine?

The correct answer is attenuated live vaccine.

Attenuated live vaccines are vaccines that use a weakened or attenuated form of the viruses or bacteria that causes a disease. Viruses or bacteria are given in a relatively small dose to replicate in the vaccinated person and to stimulate an immune response. They create a strong and long-lasting immune response but the limiting factor is that there is a possibility for a virus to revert to a form which is capable of causing disease.
