Name some vaccines which are made up of killed or inactivated pathogens.
Solution
Hint vaccines are used to boost our immune system and prevent us from serious , life threatening diseases. Vaccines expose you to a very small, very safe amount of viruses or bacteria that have been weakened or killed.
Complete answer:- To answer this you must know about killed (inactivated) vaccines.
Vaccines can be made from different types, but ultimately work on the same principle. This stimulates the immune response to recognise a pathogens or a part of a pathogen. Specifically our immune system recognizes foreign antigen which is normally not found in our body.
Killed or inactivated vaccines are made by inactivating a pathogen ,typically using heat or chemicals such as formaldehyde or formalin. This helps to destroy the pathogen's ability to replicate, but keeps it “intact” so that the immune system still recognizes it. For example polio and hepatitis A.
Inactivated polio vaccine has been given in the United States since 2000 ,protects almost all children (99 out of 100) who get all the recommended doses .For best protection, children should get four doses of polio vaccine.
Hepatitis A vaccines also consist of inactivated hepatitis A virus . hepatitis A vaccine is used for the prevention of disease caused by hepatitis A virus in persons 12 months of age and older. And the primary dose should be given at least 2 weeks prior to expected exposure to HAV.
So polio ,hepatitis A ,rabies are killed or inactivated vaccines.
Note:- Taking a vaccine is called vaccination and it is the safest way to eradicate various types of diseases from society. Inactivated vaccines could be advantageous in the fight against COVID-19 vaccines because they can be easily scaled up to large –scale production in many countries, but the potential effect is unknown .
