Coronavirus is in the air — there’s too much focus on surfaces


02 Feb 2021

Catching the coronavirus from surfaces is rare. The World Health Organization and national public-health agencies need to clarify their advice.


Lasting immunity found after recovery from COVID-19


26 Jan 2021

After people recover from infection with a virus, the immune system retains a memory of it. Immune cells and proteins that circulate in the body can recognize and kill the pathogen if it’s encountered again, protecting against disease and reducing illness severity.


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.

Long-term cardiovascular outcomes of COVID-19


09 Feb 2022

The cardiovascular complications of acute coronavirus disease 2019 (COVID-19) are well described, but the post-acute cardiovascular manifestations of COVID-19 have not yet been comprehensively characterized. Here we used national healthcare databases from the US Department of Veterans Affairs to build a cohort of 153,760 individuals with COVID-19, as well as two sets of control cohorts with 5,637,647 (contemporary controls) and 5,859,411 (historical controls) individuals, to estimate risks and 1-year burdens of a set of pre-specified incident cardiovascular outcomes. We show that, beyond the first 30 d after infection, individuals with COVID-19 are at increased risk of incident cardiovascular disease spanning several categories, including cerebrovascular disorders, dysrhythmias, ischemic and non-ischemic heart disease, pericarditis, myocarditis, heart failure and thromboembolic disease. These risks and burdens were evident even among individuals who were not hospitalized during the acute phase of the infection and increased in a graded fashion according to the care setting during the acute phase (non-hospitalized, hospitalized and admitted to intensive care). Our results provide evidence that the risk and 1-year burden of cardiovascular disease in survivors of acute COVID-19 are substantial. Care pathways of those surviving the acute episode of COVID-19 should include attention to cardiovascular health and disease.




Durability of Anti-Spike Antibodies in Infants After Maternal COVID-19 Vaccination or Natural Infection


07 Feb 2022

COVID-19 vaccination in pregnancy generates functional anti-spike (anti-S) IgG antibodies in maternal circulation that are detectable in umbilical cord blood at birth and can protect the newborn and infant from COVID-19.1-4 Anti-S IgG titers in the umbilical cord are correlated with maternal titers and are highest after late second and early third trimester vaccination.2-4 We characterized the persistence of vaccine-induced maternal anti-S IgG in infant blood and compared persistence of infant anti-S IgG after maternal vaccination vs natural infection.




Association of Major Depressive Symptoms With Endorsement of COVID-19 Vaccine Misinformation Among US Adults


21 Jan 2022

Key Points Question Are major depressive symptoms associated with increased risk of believing common misinformation about COVID-19 vaccines among US adults? Findings In this survey study including 15 464 US adults, people with moderate or greater major depressive symptoms on an initial survey were more likely to endorse at least 1 of 4 false statements about COVID-19 vaccines on a subsequent survey, and those who endorsed these statements were half as likely to be vaccinated. Meaning These findings suggest another potential benefit of public health efforts to address depressive symptoms, namely reducing susceptibility to misinformation.




Characteristics and Outcomes of Hospitalized Patients in South Africa During the COVID-19 Omicron Wave Compared With Previous Waves


30 Dec 2021

On November 24, 2021, a SARS-CoV-2 variant of concern, Omicron (B.1.1.529), was identified in South Africa as responsible for a fourth wave of COVID-19.1,2 The high number of spike mutations has raised concerns about its ability to evade vaccine and spread.3,4 We assessed hospitalized patients with a positive SARS-CoV-2 test result during the fourth wave compared with previous waves.




Why Parents Still Hesitate to Vaccinate Their Children Against COVID-19


15 Dec 2021

As of early December, more than 2.3 million children aged 5 to 11 years had developed COVID-19 and 209 had died. Although a vaccine that’s 90.7% effective in preventing the illness was authorized for younger kids in late October, these figures apparently aren’t convincing enough to persuade many parents to vaccinate their children.
