Physician assistant states that the patient received YF-VAX at a different clinic on 12OCT2021. 2 days later, on 14OCT2021, the patient saw his primary care physician and was tested for MMR immunity; it was found that the patient was not immune to MMR. The patient's primary care physician administered MMR booster to the patient on 14OCT2021. On 01NOV2021, the patient went to the travel clinic and it was found that the patient received 2 live vaccines (YF-VAX and MMR); they were not administered simultaneously and they were not administered 30 days apart. Physician assistant asks if YF-VAX or MMR vaccine need to be repeated since they were administered 2 days apart? Two or more injectable or nasally administered live vaccines not administered on the same day should be separated by at least 4 weeks to minimize the potential risk for interference. If 2 such vaccines are separated by less than 4 weeks, the second vaccine administered should not be counted and the dose should be repeated at least 4 weeks later. Physician assistant states he received these vaccines because he will be traveling."  No other adverse event was reported.
