Question: Hello 
I would like to know how long hepatitis B vaccine last 
I finished my first course in 2008 and in March when I ran a profile  It showed the vaccine wasnt as active
I was told by some health providers to take one dose of booster shot 
Another says the whole 3 I would like to know which I should go for as my spouse is positive  We have been married for 4yrs 
Thank you
Answer: Booster doses of hepatitis B vaccine extends the effectiveness of the vaccine They are usually not recommended for most healthy people but the need for booster doses is determined by a certain blood test that looks for hepatitis B surface antibody 

However on account of the positive status of spouse and the results of your serology test profile you should get a booster dose The dose will be determined by your doctor and the level of the antiHBs in your profile 

Please note that booster dose of hepatitis B vaccine is not harmful

Answer: Hello 

If you have completed the recommended three doses of the vaccine you really dont have any thing to worry about  if you have not then i advise that you should complete it 

As regards the length a complete dose usually confers long life immunity even though there is a decline in the levels of the antibody that being said  a booster dose is not harmful even though it may not really be necessary 

I hope this helps
