Racial and Ethnic Health Disparities Related to COVID-19


22 Jan 2021

One of the most disturbing aspects of the coronavirus disease 2019 (COVID-19) pandemic in the US is the disproportionate harm that it has caused to historically marginalized groups. Black, Hispanic, and Asian people have substantially higher rates of infection, hospitalization, and death compared with White people.


KFF COVID-19 Vaccine Monitor: January 2021


22 Jan 2021

The KFF COVID-19 Vaccine Monitor is an ongoing research project tracking the public’s attitudes and experiences with COVID-19 vaccinations. Using a combination of surveys and qualitative research, this project tracks the dynamic nature of public opinion as vaccine development and distribution unfold, including vaccine confidence and hesitancy, trusted messengers and messages, as well as the public’s experiences with vaccination.


Allergic Reactions Including Anaphylaxis After Receipt of the First Dose of Pfizer-BioNTech COVID-19 Vaccine


21 Jan 2021

On December 11, 2020, the US Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for the Pfizer-BioNTech coronavirus disease 2019 (COVID-19) vaccine, administered as 2 doses separated by 21 days.


Why a pioneering plan to distribute COVID vaccines equitably must succeed

COVAX is key to both immunizing the world’s poorest people and ending the pandemic.


Science advisers: publish evidence behind COVID vaccine dosing strategy


12 Jan 2021

Countries that change established coronavirus vaccine schedules must be transparent, both to maintain public trust and so others can benefit from their knowledge.

Help Fight Medicare Fraud

Medicare covers the COVID-19 vaccine at no cost to you, so if anyone asks you to share your Medicare Number or pay for access to the vaccine, you can bet it’s a scam.




Preliminary Findings of mRNA Covid-19 Vaccine Safety in Pregnant Persons


22 Apr 2021

BACKGROUND Many pregnant persons in the United States are receiving messenger RNA (mRNA) coronavirus disease 2019 (Covid-19) vaccines, but data are limited on their safety in pregnancy. CONCLUSIONS Preliminary findings did not show obvious safety signals among pregnant persons who received mRNA Covid-19 vaccines. However, more longitudinal follow-up, including follow-up of large numbers of women vaccinated earlier in pregnancy, is necessary to inform maternal, pregnancy, and infant outcomes.




Association of Race/Ethnicity With Likeliness of COVID-19 Vaccine Uptake Among Health Workers and the General Population in the San Francisco Bay Area


30 Mar 2021

Surveys have demonstrated racial differences in the public’s willingness to receive a COVID-19 vaccine1,2 but have not directly compared vaccine intentions among health workers and the general public.3 We investigated COVID-19 vaccine intentions among racially and ethnically diverse samples of health workers and the general population.




SARS-CoV-2 infection of the oral cavity and saliva


25 Mar 2021

Despite signs of infection—including taste loss, dry mouth and mucosal lesions such as ulcerations, enanthema and macules—the involvement of the oral cavity in coronavirus disease 2019 (COVID-19) is poorly understood. To address this, we generated and analyzed two single-cell RNA sequencing datasets of the human minor salivary glands and gingiva (9 samples, 13,824 cells), identifying 50 cell clusters. Using integrated cell normalization and annotation, we classified 34 unique cell subpopulations between glands and gingiva. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral entry factors such as ACE2 and TMPRSS members were broadly enriched in epithelial cells of the glands and oral mucosae. Using orthogonal RNA and protein expression assessments, we confirmed SARS-CoV-2 infection in the glands and mucosae. Saliva from SARS-CoV-2-infected individuals harbored epithelial cells exhibiting ACE2 and TMPRSS expression and sustained SARS-CoV-2 infection. Acellular and cellular salivary fractions from asymptomatic individuals were found to transmit SARS-CoV-2 ex vivo. Matched nasopharyngeal and saliva samples displayed distinct viral shedding dynamics, and salivary viral burden correlated with COVID-19 symptoms, including taste loss. Upon recovery, this asymptomatic cohort exhibited sustained salivary IgG antibodies against SARS-CoV-2. Collectively, these data show that the oral cavity is an important site for SARS-CoV-2 infection and implicate saliva as a potential route of SARS-CoV-2 transmission.




Assessment of protection against reinfection with SARS-CoV-2 among 4 million PCR-tested individuals in Denmark in 2020: a population-level observational study


17 Mar 2021

The vast majority of people who recover from Covid-19 remain protective immunity from the virus for at least six months, researchers reported on Wednesday in a large study from Denmark. The study revealed protective immunity to be approximately 80–83% in people younger than 65 years. We found no difference in immunity over the study period. Among those aged 65 years and older, immunity was estimated to be approximately 47%.
