Position on donors and smallpox vaccine: a committee opinion.

Although there is presently no definitive evidence linking vaccinia virus transmission through reproductive cells, SART/ASRM accordingly recommends that ART practitioners consider deferring donors who have recently received smallpox vaccine or contracted symptomatic vaccinia virus infection through close contact with a vaccine recipient (until after the vaccine or infectious scab has spontaneously separated). Good donor practice further suggests that donors who are not in good health, including those with recent complications from smallpox vaccine, should be similarly deferred.
