Relatively: If you really need blood, worth the risk. The greatest danger is lung damage, which is thankfully only a real problem in 1 person out of about 5000; most folks recover. Fatal type mismatches are rare today. Hives and fever are nuisances but fairly common. Blood is screened for hepatitis b and c, HIV 1 and 2, and several other viruses using 21st century technology and the risk is extremely low.
