How can Cytotect CP Biotest (CMVIG) affect the effectiveness of live attenuated measles, mumps, rubella and varicella vaccines?

Cytotect CP Biotest (CMVIG) may reduce live attenuated measles, mumps, rubella and varicella vaccine efficacy for at least 6 weeks and up to 3 months, so vaccination should wait 3 months after administration; measles impairment may persist up to 1 year, requiring antibody-status checks in measles vaccine recipients.
