Sunny Macer

Dr. Sunny Macer was the Technical Director of National Health Services.

Day 3
A corpse infected with a virus was dumped at the NHS building in the first minutes of Day 3. On the man's chest was Dr. Macer's name. She and her staff isolated the body for study, but as she talked about the infection's marks on the body with her colleague Tyler, she revealed that it appeared to be a specific type of highly lethal contagion. She determined it to be the Cordilla virus. Unrevealed at this time, the body drop-off was part of an elaborate sting orchestrated by Jack Bauer, Tony Almeida, and Gael Ortega in order to seize the actual virus from the hands of its creators' intermediary.



Later, she briefed CTU Los Angeles about the effects of the virus. Her casualty estimates were later heavily revised by Dr. Nicole Duncan, who had significantly bleaker outlook about the lethality of the virus.

Macer had a prior working relationship with Tony Almeida of CTU. She was on a first name basis with Dr. Anne Packard, the personal physician and lover of President David Palmer, who called Dr. Macer at the President's behest.

She also went to the Chandler Plaza Hotel to help with the situation there. She gave the virus test results to Michelle Dessler, which revealed that Michelle was immune to the virus.

Day 7
Around 11:00pm on Day 7, Doctor Sunny Macer was the lead medical officer at the scene of the outbreak of the bio-weapon. She tested Jack Bauer to see if he had been infected. She later delivered him the results, which tested positive.
