   The air and viruses we breathe: assessing the effect the PM2.5 air pollutant has on the burden of COVID-19

   Relevance:

   Evidence suggests an association between air pollutant exposure and worse outcomes for respiratory viral diseases, like COVID-19. However, does breathing polluted air over many years affect the suscep

2. Health service quality in 2929 facilities in six low-income and middle-income countries: a positive deviance analysis (Publications)

   Health service quality in 2929 facilities in six low-income and middle-income countries: a positive deviance analysis

   Relevance:

   BACKGROUND: Primary care is of insufficient quality in many low-income and middle-income countries. Some health facilities perform better than others despite operating in similar contexts, although th

3. Antibody and B cell responses to SARS-CoV-2 infection and vaccination (Publications)

   Antibody and B cell responses to SARS-CoV-2 infection and vaccination

   Relevance:

   Antibodies, and the B cell and plasma cell populations responsible for their production, are key components of the human immune system's response to SARS-CoV-2, which has caused the coronavirus diseas

4. SARS-CoV-2 RNAemia in a healthy blood donor 40 days after respiratory illness resolution (Publications)

   SARS-CoV-2 RNAemia in a healthy blood donor 40 days after respiratory illness resolution

   Relevance:

5. Human B cell clonal expansion and convergent antibody responses to SARS-CoV-2 (Publications)

   Human B cell clonal expansion and convergent antibody responses to SARS-CoV-2

   Relevance:

   B cells are critical for the production of antibodies and protective immunity to viruses. Here we show that patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who deve

6. Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) seroprevalence in healthcare personnel in northern California early in the coronavirus... (Publications)

   Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) seroprevalence in healthcare personnel in northern California early in the coronavirus disease 2019 (COVID-19) pandemic

   Relevance:

   OBJECTIVE: We assessed the magnitude of unidentified coronavirus disease 2019 (COVID-19) in our healthcare personnel (HCP) early in the COVID-19 pandemic, and we evaluated risk factors for infection t

7. Defining the features and duration of antibody responses to SARS-CoV-2 infection associated with disease severity and outcome (Publications)

   Defining the features and duration of antibody responses to SARS-CoV-2 infection associated with disease severity and outcome

   Relevance:

   SARS-CoV-2-specific antibodies, particularly those preventing viral spike receptor binding domain (RBD) interaction with host angiotensin-converting enzyme 2 (ACE2) receptor, can neutralize the virus.

8. Large-scale testing of asymptomatic healthcare personnel for severe acute respiratory syndrome coronavirus 2 (Publications)

   Large-scale testing of asymptomatic healthcare personnel for severe acute respiratory syndrome coronavirus 2

   Relevance:

   Large-scale, 1-time testing of > 12,000 asymptomatic healthcare personnel in California, USA, during April-June 2020 showed that prevalence of severe acute respiratory syndrome coronavirus 2 was low (

9. Modeling human adaptive immune responses with tonsil organoids (Publications)

   Modeling human adaptive immune responses with tonsil organoids

   Relevance:

   Most of what we know about adaptive immunity has come from inbred mouse studies, using methods that are often difficult or impossible to confirm in humans. In addition, vaccine responses in mice are o

10. Case-control study of individuals with discrepant nucleocapsid and spike protein SARS-CoV-2 IgG results (Publications)

    Case-control study of individuals with discrepant nucleocapsid and spike protein SARS-CoV-2 IgG results

    Relevance:

    BACKGROUND: Laboratory-based methods for SARS-CoV-2 antibody detection vary widely in performance. However, there are limited prospectively-collected data on assay performance, and minimal clinical in
