Which statement describes an inactivated vaccine?

Explanation:
Inactivated vaccines are made from pathogens that have been killed so they cannot replicate in the body. That’s why the best description is that they contain a dead microorganism. Because they don’t replicate, these vaccines tend to provoke a weaker immune response and usually require multiple doses or boosters to maintain protection. They’re generally safer for people with weakened immune systems, but they don’t typically provide lifelong immunity the way some live vaccines can. The other statements describe features of different vaccine types or are not universal characteristics of inactivated vaccines.
