1.Primary Outcome
Title Number of Participants With Immediate Unsolicited Adverse Events (AEs)
Hide Description An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the case report form (CRF) in terms of diagnosis and onset window post-vaccination. All participants were observed for 30 minutes after vaccination, and any unsolicited AEs that occurred during that time were recorded as immediate unsolicited AEs in the CRF. Reported AEs for each arm were presented as pre-specified in the study protocol.
Time Frame Within 30 minutes post vaccination

Seroconversion was defined as either a pre-vaccination HAI titer less than (<)10 (1/dilution) and a post-vaccination titer >=40 (1/dilution) or a pre-vaccination titer >=10 (1/dilution) and a >= four-fold increase in post-vaccination titer at Day 22.

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The Sponsor must have the opportunity to review at least 60 days prior to submission for publication or presentation. If review indicates that potentially patentable participant matter would be disclosed, publication or public disclosure may be delayed for a maximum of an additional 60 days to allow for filing the necessary patent applications.
