Reporter should say of the 14 cases how many were vaccinated with the serum; also note that for reported cases there are additional cases that are not reported for various reasons. Then put the whole thing in perspective by stating total hawaii vaccinations in the last year for some statistical analysis of effectiveness in the last year (365 days); the statistical percentage of effectiveness will likely be lower than calculated also due to unreported cases. However i'm sure the percentage of effectiveness will be somewhat reassuring overall i would hope to pacify alarmists; may the truth be told either way.
