Reactivated EBV 9 months after first infection. Could I be immunodeficient? Antibody count: 65 ab VCA igm; 53 ea ab igg; 431 ab VCA igg; 289 ebna igg.

No. Unfortunately ebv stays alive forever in one's lymphocytes and can get activated easily in susceptible people without known immunodeficiency. However you may call that an immunodeficiency given that all people have been infected with it yet only few would have recurrent ebv problem.
