Question

what is the use of

co-vaccine​

Answer 1

Answer:

They contain dead virus, incapable of infecting people but still able to instruct the immune system to mount a defensive reaction against an infection. Why develop Inactivated Vaccine

Answer 2

Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

I hope this helped. Thank you.
