Hi, Robert,<br /><br />Sorry to be so long in getting back to you. Busy always!<br /><br />Is it going to be that the test doesnt work on him for some reason? Maybe that could tie into how he might have the blood necessary for a vaccine--I know it's been done, but I like the way he keeps getting tested and it's negative--it throws the reader off.&nbsp;<br /><br />Just my two cents!<br /><br />Thanks,<br />Laura
