The reactance theory states that when there is a loss of opportunity, people will do anything to preserve their shot at it.
This theory makes sense in light of the nation's recent flu vaccination shortage: People are scrambling to procure this preventative measure - and it's not even flu season yet.
"We have had more inquiries on the phone of students asking for flu shots," said Carol Kozel, nursing director of UNC Student Health Services. "But there have been no cases of flu that I know of."
A regulatory agency suspended Chiron Corporation's Fluvirin influenza vaccine production license Oct. 5 for three months, preventing up to 48 million doses of the vaccine from being shipped to the United States.
In the few weeks since this announcement, North Carolina is vaccinating only people who are in the eight high-risk groups.
These groups include people who are 65 or older, children up to 6 years old and health care workers who work directly with patients, said Christine Pearson, spokeswomen for Centers for Disease Control and Prevention.
Those who are not in the high- risk groups don't have a chance to receive the shot.
"People not in those groups did receive the shot before the announcement," said Bill Furney, spokesman for N.C. Department of Health and Human Services.
Kozel said college students are not in the high-risk groups, so they might not receive the flu shot unless they have a chronic disease.
