Comment What about large groups (Score 1) 70
I think the bigger question isn't whether or not this would work on one individual. Even if the vaccine is safe and effective for this one person that doesn't mean that it's safe and effective for everyone if a large group of people were to get inoculated.
The point of clinical trials is to make sure it's safe and effective for everyone or to figure out who it's safe and effective for and to curtail specific treatments to specific groups of people based on what the research indicates is safe and effective for each group of people based on the various attributes of these groups.
Sometimes a vaccine is safe for 99+ percent of the people but it gets delayed or halted because that 1- percent are negatively affected and that small percentage of people can result in a lot of harm when the vaccine is significantly scaled up. That's why closely monitoring the results as the vaccine is being tested in a controlled environment where it's much easier to notice and appropriately respond to adverse effects is important.
