New study shows how a virus reacts to a vaccine
Most vaccines inject a small amount of the virus or bacteria into the body, which helps the body recognize the unique cell structure of the pathogen and help the body combat the pathogen should the immune system ever encounter it in the future. Seeing exactly how the body reacts to the vaccine and the virus, and how they react to each other, is sometimes a problem.
Scientists thought this issue could be solved with genome sequencing, which is a way to look at a person's unique DNA mapping and examine the over 3 million chemical building blocks that make up the human body.
Scientists took the pneumococcal bacteria, which is the cause for respiratory problems, and used genome sequencing to study the bacteria. They were able to analyze the bacteria and see that a certain vaccine was highly effective in wiping out the bacteria.
Using this methodology, scientists hope to be able to follow the changes a bacteria goes through when it mutates into different strains and be able to flag certain bacterium before they can become a large problem.
