Dear Pandemic Live Q&A 04-08-22
COVID Variants Testing and Contact Tracing Vaccines Videos
Malia Jones, PhD MPH
Live Q&As with Those Nerdy Girls are back! Dear Pandemic co-founder Dr. Malia Jones is handing over the Live Q&A torch to Dr. Chana Davis Fueled By Science. Malia and Chana will talk about 4th shots / second boosters, the new Omicron strain, vaccines for kids, and rapid tests for Omicron. ➡️ 0:00-1:24 Welcome and introductions Read more…
Everyone I know is getting Omicron. Does this mean the vaccines don’t work?
COVID Variants Vaccines
Jennifer Beam Dowd, PhD
A: No. COVID-19 vaccines are still acing their #1 job- preventing serious disease. TL;DR: Omicron is better at infecting people with immunity from vaccination or prior infection. But the vaccines (especially 3 doses) still *reduce* the risk of infection with Omicron, and *dramatically* reduce the risk of hospitalization and death. Vaccination is still the best Read more…
UPDATE on detecting Omicron with Rapid Antigen Tests:
COVID Variants Testing and Contact Tracing
Chana Davis, PhD
Over the last few weeks, rapid tests have detected many COVID cases, but often not as early as we’d like them to. With a bit of biohacking, and careful interpretation of test results, rapid tests can still be a valuable tool, despite their imperfections. THE GOOD NEWS Most rapid tests (aka lateral flow assays) can Read more…
What’s the best MASK to protect me from the Omicron variant?
COVID Variants Masks
Jennifer Beam Dowd, PhD
A: A well-fitted, high filtration mask such as N95, KN95, FFP2 or KF94. ⚠️ Omicron may be even more transmissible than previous variants, possibly due to faster replication in the upper airways, meaning people will expel lots of virus when breathing and talking. While vaccination is still your #1 defense against Omicron, it’s also a Read more…
Why should we get a booster with the existing COVID vaccine when a new one is in the works for Omicron?
COVID Variants Vaccines
Amanda Simanek, PhD MPH
A: Boosters with the original Pfizer and Moderna vaccines increase protection against the omicron variant…NOW. A few weeks ago we posted on results from Pfizer showing that: 🔵 A third dose of the original Pfizer vaccine increased neutralizing antibody titers against the omicron variant by 25-fold, compared to levels seen with only two doses 🔵 Read more…
Is it true that Omicron is less severe than previous variants?
COVID Variants
Jennifer Beam Dowd, PhD
A: We HOPE so, but we don’t know yet. The evidence so far is mixed. TL;DR We are WAY past due for some good variant news. But pinning our Omicron hopes on a less virulent variant is not wise for two reasons: 1) It might not be less severe in those who are “immune naïve” Read more…
POSTCARDS FROM THE UK: Buckle up America (and everywhere else).
COVID Variants Data and Metrics Infection and Spread
Jennifer Beam Dowd, PhD
And by buckle up, I mean BOOST-UP. And take other sensible precautions, especially leading up to the holidays. Nerdy Girl Jenn (🇺🇸 in 🇬🇧 ) writing from not-so-sunny England, home of the strangest shaped epidemic curve ever seen (Figure 1). Delta has been raging here since June and never went away. Omicron has a significant Read more…
How does one variant push out another? Why do two variants not take off at the same time in a country?
COVID Variants
Guest Author Jessica Williams-Nguyen, PhD
TL;DR: Great question! There are new variants emerging all the time. It’s a normal part of viral evolution. They compete by infecting people and making copies of themselves. Because of exponential math, even a small transmission advantage can quickly add up. This all goes back to evolution and math. Here’s how it works. A virus Read more…
Can our current COVID-19 diagnostics, like PCR tests and rapid antigen tests, detect the Omicron variant?
COVID Variants Testing and Contact Tracing
Chana Davis, PhD
A: Good news. Standard diagnostic PCR tests can pick up the Omicron variant. As far as we know, most rapid antigen tests can also detect Omicron, but tests are ongoing to determine if any specific brands are less sensitive to Omicron. Stay tuned! WHICH VARIANT DO I HAVE? 🦠 Standard diagnostic tests can’t tell you Read more…
I keep hearing all these new terms since the omicron variant came on the scene-can you clarify what all these words mean?
COVID Variants
Amanda Simanek, PhD MPH
A: Yes! Here are some explanations of many of the buzzwords flying 🦟 around right now….variant of concern, neutralizing antibodies, immune evasion and more! *Variant*: A variant is a version of the SARS-CoV-2 virus that has changes to its genetic sequence (i.e., mutations). These changes make it distinct from the other versions of the virus Read more…
OMICRON AND PFIZER/BIONTECH
COVID Variants Vaccines
Jennifer Beam Dowd, PhD
The trickle of Omicron data is quickly becoming a fountain ⛲. On the heels of yesterday’s Omicron studies, (see summary here) Pfizer today released data showing strong neutralization of Omicron after 3 doses of its vaccine, but a significant reduction for 2 doses. Highlights: ➡️ 2 doses showed significantly reduced neutralization titers against Omicron. ➡️ A Read more…
THIS JUST IN: Preliminary Omicron neutralizing antibody study
COVID Variants Vaccines
Jennifer Beam Dowd, PhD
⬇️ TL;DR: IN A LAB DISH (so NOT in real life), antibodies from vaccinated individuals (two doses of Pfizer-BioNTech), were significantly less effective at neutralizing Omicron compared to the original variant—about a 20-40-fold reduction in neutralization. While this is substantially more loss of neutralization than previous variants…this does NOT tell us how well the vaccines Read more…

The trickle of Omicron data is quickly becoming a fountain ⛲. On the heels of yesterday’s Omicron studies, (see summary here) Pfizer today released data showing strong neutralization of Omicron after 3 doses of its vaccine, but a significant reduction for 2 doses. Highlights: ➡️ 2 doses showed significantly reduced neutralization titers against Omicron. ➡️ A Read more…

⬇️ TL;DR: IN A LAB DISH (so NOT in real life), antibodies from vaccinated individuals (two doses of Pfizer-BioNTech), were significantly less effective at neutralizing Omicron compared to the original variant—about a 20-40-fold reduction in neutralization. While this is substantially more loss of neutralization than previous variants…this does NOT tell us how well the vaccines Read more…

TL;DR: Great question! There are new variants emerging all the time. It’s a normal part of viral evolution. They compete by infecting people and making copies of themselves. Because of exponential math, even a small transmission advantage can quickly add up. This all goes back to evolution and math. Here’s how it works. A virus Read more…
Can our current COVID-19 diagnostics, like PCR tests and rapid antigen tests, detect the Omicron variant?
COVID Variants Testing and Contact TracingChana Davis, PhD
A: Good news. Standard diagnostic PCR tests can pick up the Omicron variant. As far as we know, most rapid antigen tests can also detect Omicron, but tests are ongoing to determine if any specific brands are less sensitive to Omicron. Stay tuned! WHICH VARIANT DO I HAVE? 🦠 Standard diagnostic tests can’t tell you Read more…
I keep hearing all these new terms since the omicron variant came on the scene-can you clarify what all these words mean?

A: Yes! Here are some explanations of many of the buzzwords flying 🦟 around right now….variant of concern, neutralizing antibodies, immune evasion and more! *Variant*: A variant is a version of the SARS-CoV-2 virus that has changes to its genetic sequence (i.e., mutations). These changes make it distinct from the other versions of the virus Read more…
