What is the difference between killed and live vaccines?

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.

What are the three live vaccines?

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).

What is a non live vaccine?

Inactivated vaccines are another form of vaccine, where the virus is inactivated during the process of making the vaccine. Inactivated vaccines are not strongly influenced by antibodies in the host body, compared to live vaccines.

What is the difference between live and non live vaccine?

Vaccines in the United States are classified as “inactivated” or “live attenuated.” An inactivated vaccine works when the immune system responds to a piece of a bacteria or virus or to a toxin produced by the germ. Live “attenuated” vaccines mean they have been changed such that they do not cause disease.

What is an example of an inactivated vaccine?

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.

Which vaccines are live virus vaccines?

Types of Live Viral Vaccines

  • Chickenpox (varicella) vaccines.
  • FluMist (intranasal flu nasal spray)
  • Measles, mumps, and rubella (MMR) vaccines.
  • Japanese encephalitis vaccine.
  • Oral polio vaccine (no longer used in the United States)
  • Rotavirus vaccines.

Is yellow fever a live vaccine?

The vaccine is a live, weakened form of the virus given as a single shot. Vaccine is recommended for people aged 9 months or older and who are traveling to or living in areas at risk for yellow fever virus in Africa and South America.

What is the meaning of live attenuated?

Attenuated. A disease-causing virus or bacterium that is weakened in a laboratory so it cannot cause disease. Live attenuated viruses are often used as vaccines because, although weakened, they can stimulate a strong immune response.

Is influenza vaccine inactivated?

For inactivated influenza vaccines (i.e., flu shots), the vaccine viruses are then inactivated (killed), and the virus antigen is purified.

Is rabies a live vaccine?

Two rabies vaccines are available in the United States. Both vaccines contain inactivated rabies virus. HDCV vaccine (Imovax, Sanofi Pasteur) is produced in human diploid cell culture.
