A researcher UTMB has been awarded two grants worth more than $5 million to study the immune system's response to vaccines. Alexander Bukreyev will use the first grant, worth $3.5 million over five years from the National Institutes of Health, to develop a needle-free aerosol vaccine to protect against the Ebola and Marburg viruses. Both viruses have high mortality rates and there are no current effective vaccines or therapies available. Bukreyev was also granted $1.8 million from the Defense Threat Reduction Agency to study human immune responses to infections by Ebola and Marburg. The news also appears in the Houston Chronicle.
