Each day, a UCI expert will answer one of your questions about COVID-19, vaccinations, variants or the future of work. Submit questions via email.
Today’s two questions are fielded by Philip Felgner, professor in residence of physiology and biophysics, and director of UCI’s Vaccine Research and Development Center. Professor Felgner recently won a prestigious award for his contributions to designing COVID-19 vaccines.
I heard that the CDC recently revoked emergency use authorization for the PCR test for COVID-19, because the test produced too many false positives. Is this true?
In December of this year, the CDC is planning to retire its own original PCR diagnostic test that it developed at the very beginning of the pandemic. This is because the FDA has authorized hundreds of other SARS-CoV-2 diagnostic tests with higher throughput that can test for more than one illness at a time. The original test is not being withdrawn because it produced too many false positives.
So should we be concerned about false positive PCR test results?
A certain number of false positives are to be expected, and as the prevalence of COVID-19 declines, the percentage of false positives increases. At the same time, the positive predictive ability of the PCR test declines. Where PCR tests are especially useful is to confirm COVID-19 in the subgroup of symptomatic individuals. This is a group where the prevalence of true COVID-19 is higher than in the population as a whole.

Top takeaways from today’s town hall
If you missed today’s Health Affairs Town Hall on COVID-19, here are a few nuggets:
Cases across America and California continue to increase.
COVID-19 vaccines remain 93-97% protective against severe disease from all variants. This includes hospitalization and death.
How do we stop variants? Vaccinate.
Full FDA approval is expected for Pfizer and Moderna at the end of this month.
The Pfizer vaccine could receive emergency use authorization for children 5-11 years old by the FDA this winter, and for 2-5 year olds a few months after that. For children 6 months to 2 years old, the expected timeframe is early 2022.
Boosters (a 3-dose series) are expected to receive approval this fall for Pfizer and Moderna.
UCI Health has updated their FAQs. Answers are in both English and Spanish.
All UC employees and students are required to receive a COVID-19 vaccination (or apply for an exemption, exception or deferral). At UCI, the deadline for compliance is Sept. 6.
Non-compliance with the UC Vaccine Policy will result in escalating discipline.
Everyone – students and employees – is reminded that the daily symptom check is still required.
Students, staff and faculty not fully vaccinated need to participate in weekly asymptomatic testing and masking.
Drop-in asymptomatic testing for all students, staff, and faculty will be available on campus by the fall quarter.
The Future of Work website has information and resources for faculty and staff returning to work on campus either full time or in a hybrid model.

Extra COVID vaccine OK’d for those with weak immune systems
U.S. regulators say transplant recipients and others with severely weakened immune systems can get an extra dose of the Pfizer or Moderna COVID-19 vaccines to better protect them as the delta variant continues to surge, the AP reports.
How To Have Your Vaccine Confirmation On You At All Times
More and more employers, businesses and venues are requiring proof of vaccination, but the 4 inch by 3 inch cards issued by the CDC to everyone who gets at least one shot of the COVID-19 vaccine aren’t exactly sturdy. NPR suggests some ways to protect and carry your vaccine documentation.
