In practice, once you are vaccinated, your antibody level goes up because your body starts producing antibodies to fight foreign invaders .Because your body is being 'tricked' into believing that it is being invaded.These antibodies start decreasing in number as time goes on as they are not actually needed. Each time you get another shot, the antibodies increase in your body.ie second jab , 1st booster, 2nd booster etc. BUT why do you need to keep doing this?? Is there no end to this??? Funny stuff.
