kind of reminds me of that saying
"I am not actually here, just more likely to be here than not be here."
This relates as closely as i can relate it at this time.

Frequency View
Definition: Probability of an event in an experiment is the proportion (or frequency) of that event when the same exact experiment is repeated many times.
who likes it: Who likes
it:Scientists, mathematicians.
Personal View
Definition: Probability of an event is what a person who studies it believes about the chances of the event. People who define probabilities use their knowledge about the world to make "the best possible guess."
Who likes it: Philosophers, economists, mathematicians.
"
entor: Which of these two ways of looking at probability is closer to statistics?
Student: The Frequency View, because it talks about collecting data.
Mentor: A very important part of the Frequency View definition is that you need to repeat the same exact experiment to find the probability. It is
almost never possible where humans are concerned, for example, in sports or medicine. I would like to offer you several quotes, and you can find and correct the errors in them."
Quote:
"One out of eight women in the USA develops breast cancer during her lifetime. Therefore, if you are female, the probability of you having this form of cancer is1/8."
Error:
You are unique (just like everybody else). There is no way for a person to know her exact chances in anything that is connected with health. Studies show that body proportions, diet, weight, clothes preferences, number of pregnancies and breastfeeding all affect breast cancer rates in women. Even though "one out of eight" is the average for the USA, it does not tell much about each particular person.
Conclusion that may be true:
"One out of eight women in the USA develops breast cancer during her lifetime. If we randomly select 1,000,000 women and look at their medical histories, we can expect about 125,000 (not exactly!) of them to develop breast cancer."

Okay I see how I can clarify this for you better. If it were possible to vaccinate and unvaccinate the same DNA 10 times, you MAY be able to draw an accurate conclusion on that, for what the personal probability is for that person. The overall probability can be determined on the population, but the personal outcome probabilities cannot be determined on an individual based on the populations probability.
