What is the difference between live attenuated vaccines and inactivated vaccines?
What is the difference between live attenuated vaccines and inactivated vaccines?

What does it mean if a vaccine is inactivated?
Inactivated vaccines are another form of vaccine, where the virus is inactivated during the process of making the vaccine. Inactivated vaccines are not strongly influenced by antibodies in the host body, compared to live vaccines.
What is the difference between dead and live vaccine?
