24-hr Quiz on the Safety Estimates of Vaccine Boosters
Simple question - do you know the answer?
Here’s a simple mathematical exercise:
You have a medical product, say, Product X. It is supposed to prevent condition Y. Let’s say 10% of the population has a risk of bad outcome upon first exposure that makes it unlikely they will want the product in the future. Also, 0.1% of the population will have a serious adverse event that leads to hospitalization, and, of those 30% will die.
Clearly, on first exposure, your safety estimate would be 89.9% of the population can tolerate Product X.
That’s not too bad.
If the product is, say, a vaccine, and the delivery includes boosters, we need to estimate the population-level risk of double exposure.
Let’s assume of test population of 100,000 in your study:
The Vaccinologist View
First exposure: N=100,000
Drop-out or reported SAE: 10,100
Reported SAE rate (if unbiased): 10.1%
Second exposure: N=100,00-10,100 = 89,900
24-HR QUIZ QUESTION: What will the unbiased SAE population rate be for the booster in the second exposure?
