Answer 2

#Answer :-

• Live-attenuated vaccines are used more frequently for viruses rather than bacteria, since the former contain a lesser amount of genes and can be controlled more easily. The most common method in formulating live-attenuated vaccines involves passing the virus through successions of cell cultures to weaken it. This will produce a form of the virus that is no longer able to replicate in human cells. However, it will still be recognized by the human immune system, hence protecting the body from future invasions. Examples of such vaccines are measles, rubella, mumps, varicella (more commonly known as chickenpox), and influenza. The disadvantage of using this technique is that the virus may transform into a more virulent form due to a certain mutation and cause illness once injected into the body. Although this rarely occurs, it must always be taken into consideration.
