Number of Participants Who Had Reactogenicity Events (REs)Primary· 0-42 days after study vaccination
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.

Number of Participants Who Had Serious Adverse Events (SAEs)Primary· 0-180 days after study vaccination
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.

Number of Participants Who Had Adverse Events (AEs)Primary· 0-42 days after study vaccination
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.

Adverse events — posted to ClinicalTrials.gov
Time frame: Adverse events were collected from the time of investigational product administration through Day 42. Serious adverse events were collected from the time of study drug administration through Day 180..
Reporting threshold: 0%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The main purpose of this study is to get information about the safety of a flu vaccine spray, called FluMist, in children with cancer. The study is also being done to find out how much and how long the vaccine spray can be found in the nose.
