Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Conventional vaccine production causes various adverse side effects, including ____
A
Pathogens used to make vaccines may still have the ability to cause disease.
B
Vaccine production causes environmental damage
C
Vaccines are very dangerous for the human body
D
The pathogens used are very difficult to find
E
Vaccines have lethal side effects
Explanation: 

Detailed explanation-1: -These conventional vaccines use live or attenuated pathogen particles that provide immunity. Recent advancements have led to the development of nucleic acid vaccines, subunit vaccines and recombinant vaccines that use DNA, mRNA or proteins directly for vaccines.

Detailed explanation-2: -Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.

Detailed explanation-3: -Low risk for infection: Recombinant vaccines do not contain actual pathogens; only parts of the microbes (DNA, RNA, or protein) are used for making vaccines. Thus, recombinant vaccines are safer than conventional vaccines and can be given to people with weakened immune systems.

Detailed explanation-4: -Vaccines contain attenuated disease-causing organisms or toxins that initiate an immune response in the body. The first step in vaccine production is to prepare the antigen. Viruses are grown in the primary or cultured cells, bacteria are grown in the bioreactors.
