Summary Introduction
To review:
The reason behind the safety of vaccines produced by genetic engineering techniques than the vaccines produced from killed or attenuated viruses
Introduction:
Genetic engineering is the modification of an organism’s genome for a beneficial outcome. Bacteria, plants, and animals are widely engineered in research nowadays. These have endless beneficial applications in

This is a hypothetical scenario.
A recently emerged virus has been transmitting and mutating rapidly in humans throughout the world. If a vaccine that stops transmission of all current circulating variants of the virus in humans is utilized and herd immunity is achieved throughout the world, would this essentially stop 1) further transmission of the virus; 2) further mutation of the virus, respectively? Why/why not? Please answer the question succinctly and in bullet points!
The emergence of new cases of polio linked to the oral vaccine had been reported in
a number of African and Asian countries, revealing that there are now more
children being paralyzed by viruses originating in vaccines than in the wild. Viral
contamination of a biological may arise from many factors, from handling to the
origin of the materials used in the cell culture.
a What could be the reason for the outbreak in those countries?
D) The method of producing attenuated “live" vaccines involve passing the disease-
tausing virus through a series of cell cultures or animal embryos (typically chick
embryos). Explain the procedure in details and cite the reason why the method
involve passing a virus through a non-human host?
Despite our advancement in Science and Technology, thanks to the invention of the early scientists Robert Hooke and Antonie Philips van Leeuwenhoek that paved the way to the discovery of cells and the cure of many diseases, why is it that there are still many who are hesitant to have themselves immunized by COVID-19 vaccines?
