Nab response in mice after the boost immunization with DNA-S, MVA-S, or Ad5-S vaccines. The letters present different combination of vaccinations: DD for DNA-S prime and DNA-S boost; MM for MVA-S prime and MVA-S boost; AA for Ad5-S prime and Ad5-S boost; DM for DNA-S prime and MVA-S boost; AM for Ad5-S prime and MVA-S boost; MA for MVA-S prime and AD5-S boost; and DA for DNA-S prime and AD5-S boost. Three mice as a group were tested for each vaccine. The average values of each test group and the standard error bars are presented. This neutralization experiment was repeated three times with consistent results obtained
