Recurrent typhoid fever. Her 3. ?.

Hello doc, from past 1 week I'm feeling weakness, nd a bit pulling sensation around my left upper back..no pain, have headache, very dizziness... I got my liver function test done..all was normal... I suspect now that I'm having typhoid fever ..though dont have high temperature...I keep getting this fever more often...last i got was 2 nd a half years back nd dat time also I had mild swelling...nd before dat also 2-3 times more frequently....im planning to go for a widal test...I just want know dat couldn't I get rid of this completely...?? Should I go for vaccination for typhoid every year..?? Coz I'm having a 3year old baby nd I'm too scared dat she would also catch it... Can I get my kid's typhoid vaccination done as it is still 1 month to go to complete her 3..??...
