Detailed explanation-1: -mRNA vaccines have several benefits compared to other types of vaccines, including shorter manufacturing times and, because they do not contain a live virus, no risk of causing disease in the person getting vaccinated. mRNA vaccines are used to protect against: COVID-19.
Detailed explanation-2: -The live, attenuated viral vaccines currently available and routinely recommended in the United States are MMR, varicella, rotavirus, and influenza (intranasal). Other non-routinely recommended live vaccines include adenovirus vaccine (used by the military), typhoid vaccine (Ty21a), and Bacille Calmette-Guerin (BCG).
Detailed explanation-3: -With flu vaccines, for example, the live virus is injected into an embryonated egg, and then once the virus has replicated, the viral material is collected, purified and inactivated. Newer RNA vaccines can be produced from a DNA template; this can be much cheaper and faster than conventional vaccine production.
Detailed explanation-4: -Live virus vaccines use the weakened (attenuated) form of the virus. The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples. Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria.
