Clinical Study
Oak Crest Institute of Science, a Southern California Non-profit, Publishes Significant New COVID-19 Vaccination Research – 'Clinical SARS-CoV-2 Kinetic Profiles are Dependent on the Viral Strain and Host Vaccination Status'
MONROVIA, Calif., Dec. 6, 2022 /PRNewswire/ -- The Oak Crest Institute of Science announced the publication of results from a new research project in
Microbiology Spectrum (DOI: 10.1128/spectrum.04469-22). The study followed two vaccinated participants – a male and female – who developed COVID-19 independently between December 27, 2021, and January 3, 2022, the only participants to become infected with SARS-CoV-2 over this period. Using state-of-the-art molecular techniques to analyzed nasal swab samples collected at high frequency longitudinally, researchers sought to explore whether full vaccination affected early COVID-19 replication rates and/or viral loads through the various stages of infection.

"
Our ultimate conclusion in this study centers on three important points," said researcher, Manjula Gunawardana, M.P.H.
"The SARS-CoV-2 virus doubling times were similar for vaccinated and unvaccinated individuals infected with an earlier SARS-CoV-2 strain.
Vaccinated individuals have a shorter clearance phase than the unvaccinated subjects in an earlier study.
The continuous sampling protocols detected a virus mutation in one of the participants during the time they tested positive."
"Oak Crest already has a distinguished history of research
on viruses," said Paul Webster, Ph.D., and Senior Faculty at Oak Crest. including HIV prevention strategies. "We work on devices for sustained delivery of anti-HIV drugs, and the formulation of new drug candidates for the delivery, prevention, and treatment of infectious diseases. Our team has successfully transferred biomedical research from the bench to early-stage clinical trials, often first-in-human – which is a significant accomplishment for a small academic team. Our HIV clinical trials involve antiviral intravaginal rings and a subdermal implant, currently being evaluated in South Africa in a first-ever human Phase I/II clinical trial."
