Plain English Summary

Background and study aims
MVA85A is a new vaccine being developed against tuberculosis which is designed to act as a boosting immunisation in people who have already received BCG. In clinical trials so far it has been given intradermally, which means an injection just under the skin, like BCG. However, the majority of licensed vaccines are injected intramuscularly. In this study we wished to assess the safety of MVA85A delivered intramuscularly compared to the intradermal route. We also wished to study the immune response generated by the vaccine by these two routes.

Who can participate?
Healthy BCG-vaccinated adult volunteers aged 18 to 55 were recruited in Oxford, UK.

What does the study involve?
Volunteers were randomly allocated into either the first group which received MVA85A intramuscularly or the second group which received MVA85A intradermally. The dose was the same for both groups. Volunteers were followed-up for six months and underwent blood tests at several time-points.

What are the possible benefits and risks of participating?
There are some known side effects of MVA85A. In healthy adults, a standard dose of intradermal MVA85A causes a mild local reaction when injected into the skin. This is visible as redness and swelling of the skin at the injection site, which lasts a week or two before healing completely without a scar. Occasionally the site of injection is also tender for a few days. About half of volunteers also get mild flu-like symptoms (headache, tiredness, aches) following vaccination with MVA85A but these are mild. It is not known whether intramuscular MVA85A will cause the same side effects. Severe allergic reactions are rare but could potentially occur with any vaccine. Blood tests are performed throughout the trial but are not usually harmful. Having blood taken may cause slight pain and occasionally bruising at the site where the needle enters. Rarely, people feel light-headed or even faint.There are no known benefits of participating in this research.

Scientific title

Safety and immunogenicity of candidate tuberculosis (TB) vaccine MVA85A administered by the intramuscular route and the intradermal route: a phase I randomised active controlled trial


Study hypothesis

This is a phase I study that will compare the safety and immunogenicity of candidate tuberculosis (TB) vaccine MVA85A administered by the intramuscular route and the intradermal route in healthy adult individuals who have been previously vaccinated with Bacillus Calmette-Guerin (BCG).

MVA85A is a modified vaccinia virus Ankara expressing antigen 85A from Mycobacterium tuberculosis. All subjects will receive a single vaccination of 1 x 10^8 pfu (plaque forming units) of MVA85A, one group via the intramuscular route and one group via the intradermal route.

Total duration of follow-up: 6 months.

Intervention type



Phase I

Drug names


Primary outcome measure

Safety data in both groups, as assessed by the frequency, incidence, and nature of adverse events (AEs) and serious adverse events (SAEs) during the study. Safety is measured throughout the one year follow up period, but specifically on the following days: 2, 7, 14, 28, 56, 84, 168 and 364. Blood for safety testing is taken at Days 7 and 28.

Secondary outcome measures

Immunogenicity data in both groups. This will be obtained from exploratory immunological laboratory investigations on blood samples taken at screening, and throughout follow up. Immunogenicity is measured throughout the one year follow up period, but specifically on the following days: 2, 7, 14, 28, 56, 84, 168 and 364.
