PATHOLOGY

Detailed explanation-1: -Live attenuated vaccines: These vaccines contain the bacteria or virus that is alive but weakened. Some examples of live attenuated vaccines are: Rotavirus vaccine. Shingles vaccine.

Detailed explanation-2: -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.

Detailed explanation-3: -Live-attenuated vaccines contain live pathogens from either a bacteria or a virus that have been “attenuated, ‘’ or weakened. According to Dr. Scully, live-attenuated vaccines are produced by selecting strains of a bacteria or virus that still produce a robust enough immune response but that does not cause disease.

Detailed explanation-4: -Viral vector vaccines Vector vaccines contain a weakened version of a virus-a different virus than the one that causes COVID-19-that teaches your cells to make a harmless piece of coronavirus spike protein.

Detailed explanation-5: -Inactivated (Killed) Vaccines Examples of inactivated vaccines include: inactivated poliovirus (IPV) vaccine, whole cell pertussis (whooping cough) vaccine, rabies vaccine and the hepatitis A virus vaccine.
