As the number of cases of H1N1 continues to rise on campus, University Health Services (UHS) hosted its first vaccination clinic Friday.

About 1,000 doses of the H1N1 nasal spray vaccine were administered to students who made appointments online through the UHS Web site. The next H1N1 nasal spray vaccination clinic will be held Friday, with another 1,000 doses available.

UHS also announced to students with chronic medical conditions like asthma and diabetes that an injectable form of the vaccine will be made available to them this week. Students with these conditions were sent an e-mail Sunday.

"It is more important for at-risk groups to get the vaccine, though we encourage everyone to get it," UHS Clinical Director Evan Pattishall said.

The university recognizes about 3,700 students as having chronic medical conditions, and there are about 1,000 injectable doses available, he said. The injectable vaccine will be available Tuesday, Wednesday and Thursday. Appointments can be made online at the UHS Web site.

Other students are still encouraged to receive the nasal spray at UHS clinics. Those who registered for the first clinic were able to receive the vaccine free of charge at the Student Health Center.

Doris Guanowsky, senior associate director of UHS, helped manage the foot traffic and kept order during the clinic. She said UHS officials were pleased with the student turnout and the apparent success of their first H1N1 vaccination clinic.

"It's been interesting, because no one's been complaining," Guanowsky said. "Students have been really receptive to the nasal spray."

Because the spray can be dispensed quickly -- a five-minute appointment per patient -- several students said they appreciated how quickly they were able to be seen by the nursing staff.

"I literally was in here 30 seconds," said Joanna Malfitano (junior-biobehavioral health) "Waiting after is the longest part."

Students were told to wait about 15 minutes before leaving UHS to ensure they had no sudden adverse reactions to the nasal spray, a weakened form of the live virus. Risks for the 18-to-49 age group include developing a sore throat, headache, cough, chills and nasal congestion.

Those who should not receive the nasal spray include pregnant women and anyone with a weakened immune system or long-term health problems.

Multiple students acknowledged they were encouraged to get the vaccine because it is free, but Guanowsky said it is just as important for students to get the $26 seasonal flu vaccine as well.

"You have the risk of getting sick twice," Guanowsky said.
