The Black Plumb Line: Re-evaluating Race and Africanist Images in Non-Black Authored American Texts

This study evaluates Africanisms (representations of racialized or ethnicized blackness) within three contemporary non-black authors’ texts: Jewish American Saul Bellow’s novel Henderson the Rain King, white southerner Melinda Haynes’ novel Mother of Pearl, and Nyurican poet Victor Hernández Cruz’s works “Mesa Blanca” and “White Table.” Though not entirely unproblematic, each selection somehow redefines black identity and agency to challenge denigrated representations of Africanist people and culture. In the process, each author subverts faulty components of American myths of racial purity, particularly stratifying black-white dualisms that promote whiteness, racial supremacy, and resulting undue privilege. This study also traces how Bellow, Haynes and Cruz adopt and/or adapt rhetorical strategies, mutual investments in history and shared identity cues that align these writers and their works with aspects of the African American literary tradition as well as kindred authors of African descent. Racial performance and the social construction of identity factor heavily into this project as the chosen writers also challenge critical tendencies to equate authors’ identities with authors’ aims, particularly when writers cross identity boundaries to dismantle traditional patterns of racial supremacy and racism. The ambiguously raced author Jean Toomer and fellow writer Carl Van Vechten also serve as key introductory comparative figures within this study. Ultimately, this project underscores the continued responsibility American writers have to address the cultural artifact American imaginations have made of racialized blackness within our national literature and corresponding social spaces and institutions

Risk of COVID-19 after natural infection or vaccinationResearch in context

Summary: Background: While vaccines have established utility against COVID-19, phase 3 efficacy studies have generally not comprehensively evaluated protection provided by previous infection or hybrid immunity (previous infection plus vaccination). Individual patient data from US government-supported harmonized vaccine trials provide an unprecedented sample population to address this issue. We characterized the protective efficacy of previous SARS-CoV-2 infection and hybrid immunity against COVID-19 early in the pandemic over three-to six-month follow-up and compared with vaccine-associated protection. Methods: In this post-hoc cross-protocol analysis of the Moderna, AstraZeneca, Janssen, and Novavax COVID-19 vaccine clinical trials, we allocated participants into four groups based on previous-infection status at enrolment and treatment: no previous infection/placebo; previous infection/placebo; no previous infection/vaccine; and previous infection/vaccine. The main outcome was RT-PCR-confirmed COVID-19 >7–15 days (per original protocols) after final study injection. We calculated crude and adjusted efficacy measures. Findings: Previous infection/placebo participants had a 92% decreased risk of future COVID-19 compared to no previous infection/placebo participants (overall hazard ratio [HR] ratio: 0.08; 95% CI: 0.05–0.13). Among single-dose Janssen participants, hybrid immunity conferred greater protection than vaccine alone (HR: 0.03; 95% CI: 0.01–0.10). Too few infections were observed to draw statistical inferences comparing hybrid immunity to vaccine alone for other trials. Vaccination, previous infection, and hybrid immunity all provided near-complete protection against severe disease. Interpretation: Previous infection, any hybrid immunity, and two-dose vaccination all provided substantial protection against symptomatic and severe COVID-19 through the early Delta period. Thus, as a surrogate for natural infection, vaccination remains the safest approach to protection. Funding: National Institutes of Health
