Bivalent boosters provide additional protection from BA.5, XBB, and XBB.1.5 Coronavirus Disease COVID Bivalent Vaccine Booster BA5 XBB XBB15 CDCMMWR CDCgov
They made preliminary estimates of bivalent messenger ribonucleic acid coronavirus disease 2019 vaccine effectiveness against symptomatic infection by Omicron BA.5- and XBB-related subvariants. The study duration was December 1, 2022, and January 13, 2023.
About the study In the present study, researchers recruited individuals receiving SARS-CoV-2 testing at ICATT sites between December 1, 2022, and January 13, 2023, suspecting one or more COVID-19 and similar illnesses. They provided extensive information on vaccination history, current symptoms, previous SARS-CoV-2 test results, and pre-existing health conditions, if any.
The team also computed the relative VE of a bivalent booster and odds ratios using multivariable logistic regression models. For VE calculations based on SGTF/SGTP status, they used the formula x 100. Among the results for 29,175 nucleic acid amplification tests , 10,596 and 3,052 were SGTF and SGTP, respectively. Between December 1, 2022, and January 2, 2023, XBB.1.5 constituted 33% of samples exhibiting SGTP, with XBB.1.5 accounting for 38% of them, and this rose to 43% between December 18, 2022, and January 2, 2023.

Tracking excess of maternal deaths associated with COVID-19 in Brazil: a nationwide analysis - BMC Pregnancy and ChildbirthBackground The COVID-19 pandemic brought a new challenge to maternal mortality in Brazil. Throughout 2020, Brazil registered 549 maternal deaths, mainly in second and third-trimester pregnant women. The objective of this study was to estimate the excess maternal deaths in Brazil caused directly and indirectly by Covid-19 in the year 2020. In addition, we sought to identify clinical, social and health care factors associated with the direct maternal deaths caused by Covid-19. Methods We performed nationwide analyses based on data from the Mortality Information System (SIM) for general and maternal deaths and the Influenza Epidemiological Surveillance System (SIVEP-Influenza) for estimates of female and maternal deaths due to COVID-19. Two distinct techniques were adopted. First, we describe maternal deaths directly caused by covid-19 and compare them with the historical series of deaths from covid-19 among women of childbearing age (15 to 49 years). Next, we estimated the total excess maternal mortality. Then, we calculated odds ratios for symptoms, comorbidities, social determination proxies and hospital care aspects between COVID-19 maternal deaths and deaths of women of childbearing age who were not pregnant or no maternal deaths. We chose women of childbearing age (15 to 49 years) as a reference because sex and age introduce differentials in the risk of COVID-19 death. Results Most maternal deaths occurred during pregnancy compared to postpartum deaths month by month in 2020 (μ = 59.8%, SD = 14.3%). The excess maternal mortality in 2020 in Brazil was 1.40 (95% CI 1.35–1.46). Even considering excess mortality due to COVID-19 for the childbearing age female population (MMR 1.14; 95% CI 1.13–1.15), maternal mortality exceeded the expected number. The odds of being a black woman, living in a rural area and being hospitalized outside the residence municipality among maternal deaths were 44, 61 and 28% higher than the control group. Odds of hospitalization (OR 4.37; 95
