At 10:25 a.m. Thursday, CU 色吧亚洲 senior Olivia Parsons became the first participant to receive vaccination in a national study aimed at answering a critical question in the fight against COVID-19: Does the Moderna shot prevent people from spreading the virus?

鈥淗onestly, I felt like it was my civic duty to participate,鈥� said Parsons, 22, moments after a doctor at the Clinical and Translational Research Center (CTRC) on the 色吧亚洲 campus administered her first Moderna vaccine. 鈥淚t鈥檚 an honor.鈥�

Parsons is among 12,000 students, ages 18 to 26, from 21 universities who will participate in a five-month, federally-funded study led by the COVID-19 Prevention Network (CoVPN) at Fred Hutchinson Cancer Research Center in Seattle.

CU 色吧亚洲 was the first site to roll it out, with study leaders on Thursday vaccinating 11 of the roughly 700 CU 色吧亚洲 student volunteers who will ultimately participate.

鈥淲e know from previous trials that this vaccine protects those who are vaccinated from moderate and severe disease, hospitalization and death. The question now is: Does it also protect others?鈥� said Integrative Physiology Professor and CTRC Director Christopher DeSouza, co-principal investigator for the CU 色吧亚洲 site. 听

National study leader Dr. Larry Corey, principal investigator of CoVPN鈥檚 operations program, added that the purpose of this trial is to tell us whether a person can become infected after they鈥檝e been vaccinated and if the vaccine will stop the virus from spreading from person-to-person.

To find out, researchers will vaccinate half the students right away, while vaccinating the other half four months later. Volunteers will then be asked to swab their nose鈥攖ypically the site of first infection鈥攅very day, get tested twice weekly via CU 色吧亚洲鈥檚 on-campus saliva monitoring program and complete daily questionnaires about symptoms via an app on their phone. They鈥檒l also have their blood drawn periodically.

Collectively, all this data will enable researchers to capture infections in real time and track the viral load, or the amount of viral particles present in an infected individual, over the course of an infection.

Researchers will also track 25,500 close contacts of participants nationwide.

If a study participant tests positive, close contacts will be asked to collect daily nasal swabs for 14 days as well as blood samples to determine if they, too, get infected.

Each student participant will be followed for five months, with the vast trove of resulting data providing new insight into how well the vaccine prevents transmission鈥攊ncluding asymptomatic transmission鈥攐f SARS CoV-2, the virus that causes COVID-19.

鈥淯ntil we know how much vaccination protects you from infecting others, it is hard to know how much to relax restrictions and fully reopen things,鈥� said co-principal investigator Dr. Brian Stauffer, medical director of the Clinical and Translational Research Center at CU 色吧亚洲 and chief of cardiology at Denver Health Medical Center.

The researchers say that while the study centers on college students, the findings will be highly applicable to the population at large.

They hope to report results prior to fall 2021.

Although only the Moderna vaccine will be used in the trial, Corey said the results will apply equally well to the Pfizer-BioNTech vaccine, which uses a similar technology (called mRNA) to train the body鈥檚 immune system to recognize and attack SARS-CoV-2.

The findings will be key to informing science-based decisions about mask use and social distancing post-vaccination. The results can also inform college administrators as they craft plans for returning to campus in the fall, said DeSouza.

Infection rates can be high on college campuses due to students living in close quarters, and many who are infected have no symptoms. Therefore, a campus provides a 鈥渕odel setting鈥� for studying transmission鈥攑articularly asymptomatic transmission, he said.

A nationwide survey found that more than 397,000 infections were counted at 1,800-plus universities after reopening in the fall of 2020. Two separate studies last October reported that SARS-CoV-2 infections among young people aged 18-22 increased 55% nationally between August and September 2020. Between June and August 2020, young people aged 20-29 had the highest incidence of SARS-CoV-2 infection in the United States, accounting for more than 20% of cases.Because CU 色吧亚洲 already requires students living in the residence halls to participate weekly in saliva surveillance for SARS CoV-2, the campus was well-positioned to be an early participant in the trial, said DeSouza.

In the coming four to six weeks, the national and CU 色吧亚洲 teams will continue to recruit participants. If students in the phase of the study designated for a delayed vaccine have an opportunity to be vaccinated before that, they are not prohibited from doing so but it is hoped that they will complete the study.

Study volunteer Chase Willie, a senior media design major at CU 色吧亚洲, said Thursday鈥檚 jab in the arm felt like a dose of much-needed relief.

鈥淚 miss not being scared - just being able to go out and interact with people and laugh and have fun and not worry that I am going to bring something back to my parents,鈥� Willie said. 鈥淚 know this is just the first shot, but it feels like the beginning of something good.鈥�

The trial is funded by the Federal COVID-19 Response Program and the National Institute of Allergy and Infectious Diseases. The COVID-19 Prevention Network (CoVPN) was formed by the National Institute of Allergy and Infectious Disease (NIAID) at the US National Institutes of Health.
