What to do if you are exposed to someone with symptoms of or confirmed COVID-19

Testing and Contact Tracing

A: Our colleagues @IMPACT4HC provide great guidance in this infographic. Key takeaways: *Get tested for COVID-19 if you have been exposed.* Vaccinated, unvaccinated, symptomatic, asymptomatic – everyone should follow up with a test to prevent the spread of infection to others. *If you have an exposure, go for the PCR test.* PCR tests do a Read more…

Are vaccinated people infected with Delta *really* as contagious as the unvaccinated?

COVID Variants Infection and Spread

A: Probably not. And when you count the reduction in getting infected in the first place, vaccinated people are much less likely to transmit the virus. 💥 TL;DR: Vaccinated people likely *can* transmit the virus, but this risk is NOT the same as the unvaccinated. Among growing concerns about Delta, recent news that vaccinated people Read more…

How does a pandemic end?

Uncategorized

A: I’ll borrow a phrase from T.S. Eliot. This is how a pandemic ends. Not with a bang but a whimper. There is no single indicator that a pandemic is over. In our modern times, we wait for a statement from the World Health Organization (WHO) to declare when a pandemic begins and when it Read more…

How does natural immunity to SARS-CoV-2 infection differ from immunity generated by COVID-19 vaccines?

Biology/Immunity Vaccines

A. COVID-19 vaccines induce higher levels and a broader range of neutralizing antibodies to the receptor binding domain (RBD) of the spike protein than does natural infection. Vaccine-induced antibodies are less likely to be affected by changes in the RBD seen in the current SARS-CoV-2 variants, and are therefore more likely to be more effective Read more…

What should I make of the “leaked” CDC slides last week? Is Delta worse than we thought?!

COVID Variants Data and Metrics Infection and Spread

A: KEEP CALM AND VAX ON. Just when we thought our summer might be more relaxing than last year, SARS-CoV-2 is humbling us again. But despite the emotionally amped up headlines (which are, after all, designed to make you click), we’re here to reassure you that in countries with access to vaccinations, the trajectory is Read more…

What do the new CDC mask guidelines really mean?

Masks

A: The take-home message is that mitigation works. What we have learned from four influenza pandemics, HIV, and SARS pandemics in the last 100 years is that taking steps to protect ourselves and others works. The CDC guidelines released earlier suggest that vaccinated people in virus hotspots across the country should wear masks indoors. This Read more…

What should I do about the large discrepancies in vaccine efficacy against the Delta variant being reported across studies?

COVID Variants Vaccines

A: Delta variant, waning immunity, imperfect measurement, or something else? There are a number of reasons why COVID-19 vaccine efficacy may differ across studies. These new reports are measuring the effectiveness of the vaccines in real world settings instead of in a clinical trial. Isolating individual variables in a real-world setting can be difficult. Instead, Read more…
