A systematic screening for measles, mumps, rubella (MMR) and varicella zoster virus (VZV) in HIV-positive adult immigrants in Spain was evaluated, and factors associated with MMR and VZV vaccines' indication were studied. Every HIV-positive immigrant was tested for VZV and MMR-IgG. MMR vaccine was indicated to patients with lymphocytes CD4+ >200 cells/mm3 and a negative measles-IgG, a negative mumps-IgG and/or a negative rubella-IgG. VZV vaccine was indicated to every VZV-IgG negative patient with CD4+ >400 cells/mm3. In total, 289 patients were screened; seroprevalence was 95.2%, 92.2%, 70.3% and 89.3% for VZV, measles, mumps and rubella IgG, respectively. Having a negative VZV-IgG was statistically associated with coming from sub-Saharan Africa (prevalence ratio [PR]: 6.52; 95% CI: 1.71–24.84; p=0.006), while having secondary education was a protective factor (PR: 0.25; 95% CI: 0.07–0.97; p=0.045). Fourteen patients (4.8%) had indication of VZV vaccine; vaccination was feasible in 21.4% of them at first visit. Eighty-one patients (29.7%) had indication of MMR vaccine, most of them due to mumps-IgG negative (53.1%) or rubella-IgG negative (24.7%). Age < 30 years at first visit was the only factor statistically associated with MMR vaccine indication (PR: 1.47; 95% CI: 1.02–2.11; p=0.04). According to CD4+ cell counts, vaccination was feasible in 71.6% of patients at first visit. In conclusion, more than a third of HIV-infected immigrant patients are susceptible to at least one easily preventable infectious disease. Especial attention should be given to immigrant women of childbearing age.
