I received a tetanus vaccination less than 10 years ago when I was in the military. I recently started donating plasma and donation center gave me another tetanus shot to boost the tetanus antibodies that I already had. My antibodies went up for a while, and as of recently the plasma donation center said that they went down quite a bit. Why would they go down?
Also, I should mention, I'm not sick, or running a temperature. Haven't gotten any infection. However, I work out and weight train, and I have been on a cut the past 2 weeks. Nothing extreme and highly nutritious meals only. Could this be the reason why? And if so, how exactly would this affect my tetanus immune globulin levels?
