Distribution of IFN-alpha/beta gene signature scores at 7 to 10 days after Dose 1. IFN alpha/beta gene signature scores were calculated as the average fold change in a panel of 21 type 1 IFN-inducible genes. The distribution of IFN alpha/beta gene signature scores ranged from -4 to 4, with -4 representing the lowest level of activity and 4 representing the highest level of activity. The percentage of subjects by IFN-alpha/beta gene signature score for each treatment group were compared.
The geometric mean titers for each strain between Day 0 and 28 were examined.
Reactogenicity events (REs) are predefined solicited adverse events (AEs) that can potentially occur after vaccine administration. The REs for this study included fever, runny nose/nasal congestion, sore throat, cough, vomiting, headache, muscle aches, chills, tiredness, and irritability.
An SAE is any AE that results in any of the following outcomes: •Death • Life-threatening • Inpatient hospitalization or prolongation of existing hospitalization • Persistent or significant disability or incapacity • Congenital anomaly/birth defect (in the offspring of a study participant) • An important medical event that may may jeopardize the study participant and may require medical or surgical intervention to prevent one of the outcomes listed above.
An AE is any untoward medical occurrence in a patient or clinical investigations study participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
A significant new medical condition is defined as a new diagnosis of a chronic medical condition that does not meet the criteria of a SAE.

CAIV-T is an investigational live cold-adapted trivalent influenza virus vaccine developed by AstraZeneca PLC (ticker AZN). It is designed to protect against influenza virus types A and B and has been studied in both children and older adults. It is also known as CAIV-T, Liquid, and CAIV-T and TIV.
CAIV-T is being developed for the prevention of influenza caused by influenza virus types A and B. Clinical trials have evaluated it in adults aged 60 years and older, in healthy children, and in children attending day care. It is not approved for any indication and remains investigational.
CAIV-T is developed by AstraZeneca PLC, which trades under the ticker AZN. The company has sponsored the clinical trial program for this vaccine candidate.
CAIV-T is in Phase 3 clinical development. It is an investigational product and has not been approved by the FDA or any other regulatory agency for any indication.
CAIV-T has been studied in completed trials including NCT00217230, a Phase 3 trial in adults aged 60 years and older in South Africa; NCT00192426, a Phase 3 trial evaluating immune response when given with oral polio vaccine in healthy children; NCT00192387, a Phase 2 viral shedding trial in healthy children in the United States; and NCT00192361, a Phase 3 trial in children attending day care in Finland.
