A Phase I Study of Candidate Influenza Vaccines MVA-NP+M1 and ChAdOx1 NP+M1

Seasonal Influenza Clinical Trial

Official title:
A Phase I Study to Determine the Safety and Immunogenicity of Vaccination Regimens Employing the Candidate Influenza Vaccines MVA-NP+M1 and ChAdOx1 NP+M1

Clinical Trial Summary

This will be a randomised observational phase 1 study in 48 healthy volunteers aged 18-50. The study is assessing safety and immunogenicity of viral vectored vaccines ChAdOx1 NP+M1 and MVA NP+M1 in heterologous prime-boost regimens. A crossover design will allow comparison of the two vaccines. Volunteers will be divided into 4 groups (n=12 in each group). Groups will be recruited simultaneously to control for seasonal changes in influenza. This is because at certain times of year there is likely to be a higher naturally acquired T cell response to influenza than at other times due to circulating influenza virus in the community.

The study has been extended to include 2 additional groups (group 5 & 6), each containing 12 healthy adults aged 50 years or above. Group 5 will receive ChAdOx 1 NP+M1 on day 0, and group 6 will receive this with an additional boost of MVA-NP+M1 8 weeks later.
