CLINICAL MEDICINE

Detailed explanation-1: -Vaccines expose you to a very small, very safe amount of viruses or bacteria that have been weakened or killed. Your immune system then learns to recognize and attack the infection if you are exposed to it later in life.

Detailed explanation-2: -Whole-Pathogen Vaccines Traditional vaccines consist of entire pathogens that have been killed or weakened so that they cannot cause disease. Such whole-pathogen vaccines can elicit strong protective immune responses. Many of the vaccines in clinical use today fall into this category.

Detailed explanation-3: -We often hear the phrase “inactivated vaccine”, but how exactly do scientists inactivate a virus or bacterium? A common way of inactivating a live microorganism is to use formaldehyde (also known as formalin or formol).

Detailed explanation-4: -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.
