Time Frame Solicited events were collected for 8 days after each vaccination, unsolicited events through 21 days after last vaccination, and serious adverse events and new onset chronic medical conditions through 180 days after last vaccination.
Additional Description For events solicited on a Memory Aid in the 8 days after vaccination, a participant was considered to have one event if it was reported as experienced at any time in the 8 day period.

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 agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.
