Country I was wondering that every vaccination we create doe

Country. I was wondering that every vaccination we create doesn\'t work on everyone. So how can we really vaccine work on 95% of people and not 5 %? Is this based off of one vaccination?

Solution

No, this is not based off of one vaccine. While testing a vaccine, there is always a null hypothesis stated along with the vaccine, being Ho being that the vaccine will work on 100% of the people. After test subjects are vaccinated, the effect of the vaccine is checked to prove or disprove the null hypothesis. The occurrence of 95% and 5% states that in less than 5% occurrences, the null hypothesis doesn\'t hold true. This value is of 5% is a standard while calculating null hypothesis, alternatively a value of 1% is also taken in some cases. Since , this is a matter of survey and statistical analysis of how many people have a positive effect of the vaccine, the statistics as 95-5 pertain for most of the vaccines. The 5% and 1% values are called as significance level denoted by alpha.
