Which of the following is NOT a live vaccine?

MMR
Typhoid
Meticillin
Yellow Fever

The correct answer is: Meticillin

Meticillin is an antibiotic, not a vaccine, which is why it is the correct choice for the question regarding which option is not a live vaccine. Live vaccines are made from weakened forms of the virus or bacteria they protect against, allowing the immune system to recognize and fight off the pathogen without causing the disease. In contrast, MMR (measles, mumps, and rubella), Typhoid (specifically the oral form), and Yellow Fever vaccines are all examples of live attenuated vaccines. These vaccines use a weakened version of the pathogen to stimulate an immune response without causing the full-blown disease. Therefore, recognizing Meticillin as the non-vaccine option is essential for understanding the classification of vaccines and their roles in immunization.
