title: [Preliminary study on nasal spray of interferon alpha-2b used for prevention of rubella and measles virus infections].
abstract: OBJECTIVE
  To evaluate the efficacy of the interferon alpha-2b nasal spray in prevention of rubella and measles virus infections.
  
  
  METHODS
  The properly selected volunteer groups have been divided into interferon alpha-2b experimental and control group. The experimental group received interferon alpha-2b treatment by nasal spray for 2 days before the immunization, then both groups were challenged with rubella and measles attenuated live vaccine respectively through nasal spray. The sera from pre-immunization and 21 and 28 days after immunization were collected to test the IgG antibody titers. The influence on the viral antibody titer reflects the viral preventive effect by interferon alpha-2b.
  
  
  RESULTS
  The antibody titer difference of measles virus between experimental and control group was 1.26 (21 day) and 2.96 (28 day), there were statistically difference between them; the difference of rubella virus was 0.95 (21 day) and 0.37 (28 day), but there were no statistically differences found.
  
  
  CONCLUSIONS
  The preliminary results showed that the interferon alpha-2b can be used as prevention method for measles and rubella viral infections.
