Hi thanks for the query. Widal 1:80 is considered normal dilution only and it has high false positive rate. So dont go by numbers and Only if it is more than 1:160 and titres are rising and clinically correlating it should be considered as positive. Anyway you took vaccine which has good efficacy so relax as it will protect you from typhoid bacteria for three years and repeat vaccine three yearly. Most important it spreads through contaminated water and food so good hygiene practices is must to prevent it.
