Preliminary findings of mRNA Covid-19 vaccine safety in pregnant persons. For children whose mothers received one dose before pregnancy and two doses during pregnancy, VE against infection was 89% during the first 2 months of life, 73% during the first 4 months of life, and 48% up to 6 months of life. During the Omicron-predominant period, hospitalization rates increased among unvaccinated persons and those who completed a primary series, with and without receipt of a booster or additional dose (Figure 2). Female sex was a protective factor (HR, 0.52), while residence in a nursing home or low-income area was a risk factor. Most mothers (66.14%) were between ages 25 and <35 years, and more than a quarter (27.27%) were of Asian race, 5.16% were Black, 24.44% were of Hispanic ethnicity and 37.57% were White. During the Omicron dominant period, maternal vaccination with at least two doses reduced the infants risk of testing SARS-CoV-2 positive by 43% (95% CI: 4, 69) during the first 2 months of life, 36% (95% CI:11, 55) during the first 4 months of life, and 41% (95% CI: 25, 53) during the first 6 months of life (Supplemental Table2). Kim, L. et al. Starting the week ending December 4, 2021, Maryland data are not included in weekly rate calculations but are included in previous weeks. We did not assess whether vaccines received before pregnancy or immediately after pregnancy were associated with a reduced risk of testing positive for SARS-CoV-2 in infants. Pediatrics. Data about boosters was only available for those over 50. These proportions are lower compared with 47.3% of White persons who received a primary series and 54.5% of eligible adults who received a booster dose. Relative to the Delta-predominant period, Black adults accounted for a larger proportion of unvaccinated adults during the Omicron-predominant period, and age-adjusted hospitalization rates for Black adults increased to the highest rate among all racial and ethnic groups for any week during the pandemic. and statistical significance was assessed at two-sided p0.05. Variances were estimated using Taylor series linearization method. Hospitalization rates during peak Omicron circulation (January 2022) among unvaccinated adults remained 12 times the rates among vaccinated adults who received booster or additional doses and four times the rates among adults who received a primary series, but no booster or additional dose. * Information on the impact that booster or additional doses of COVID-19 vaccines have on preventing hospitalizations during Omicron predominance is limited. Infants were followed from birth until the first positive SARS-CoV-2 test by PCR at age 2, 4, or 6 months, with censoring due to death, health plan disenrollment, or end of follow-up (May 31, 2022). Over the entire study period, the incidence of hospitalization for COVID-19 was lower during the first 6 months of life among infants of vaccinated mothers compared with infants of unvaccinated mothers (21/100,000 person-years vs. 100/100,000 person-years). J. Med. Shook, L. L. et al. Adults whose vaccination status had not yet been verified using the immunization information system data were considered to have unknown vaccination status and were included in total proportions but not stratified by vaccination status. Danino, D. et al. Open 5, e2233273 (2022). In the first study, a team led by US Centers for Disease Control and Prevention (CDC) researchers analyzed data on 192,509 hospitalizations from more than 250 hospitals in 13 states participating in the COVID-19Associated Hospitalization Surveillance Network from Jan 1, 2021, to Apr 30, 2022. In our primary analysis, we implemented a cohort study design where we used Cox proportional hazards models that allow for time-varying covariates to estimate the SARS-CoV-2 infection hazard ratio (HR) in infants of mothers vaccinated with at least 2 doses of mRNA COVID-19 vaccines during pregnancy and 1 dose only versus mothers who were unvaccinated during pregnancy. In the meantime, to ensure continued support, we are displaying the site without styles The state has administered 3.2 million vaccine doses since Dec. 1 alone, but lagging rates between full vaccination and first doses for adults especially (82.6% vs. 95%) are becoming a point of . TN, NMF, WH, and SA wrote the software. For mothers of infants in the cohort, we extracted from the electronic health record data: age at pregnancy onset, self-reported race/ethnicity (Asian, Black, Hispanic, Pacific Islander, Multiracial, Native American, Other, White), the primary KPNC facility at which the woman received most of their health care, insurance payor (dichotomized as Medicare/Medicaid/other subsidized insurance and Other), neighborhood deprivation index [NDI]35 categorized into quartiles with higher values representing greater deprivation), pre-pregnancy body mass index (BMI=kg/m2; underweight <18.5, normal 18.524.9, overweight 25.029.9, obese 30.0), pre-pregnancy diabetes status, pre-pregnancy hypertension, and parity (0, 1, 2, 3, 4). **** ICU admission and IMV are not mutually exclusive categories, and patients could have received both. And in a second large study during the Omicron period, older people, men, and residents of nursing homes or in low-income areas were most at risk for post-booster COVID-19 death in England, but the risk was very low. The report shows people catching Omicron are: 31% to 45% less likely to go to A&E. 50% to 70% less likely to be admitted to hospital for treatment. Thank you for visiting nature.com. Mountain lions, a bobcat, red foxes, black bears, and skunks represent the latest avian flu cases in mammals. Rep. 71, 2630 (2022). Mortal. Centers for Disease Control and Prevention. Vaccination status is not available for Iowa and cases from Iowa are excluded from analyses that examined vaccination status. Moline HL, Whitaker M, Deng L, et al. and JavaScript. U.S. regulators had authorized the Pfizer/BioNTech COVID-19 vaccine for children aged 5 to 11 years in October, prior to the Omicron surge. part 56; 42 U.S.C. "The high hospitalization rates in unvaccinated compared with vaccinated persons with and without a booster dose underscores the importance of COVID-19 vaccinations in preventing hospitalizations and suggests that increasing vaccination coverage, including booster dose coverage, can prevent hospitalizations, serious illness, and death," the researchers wrote. Acosta AM, Garg S, Pham H, et al. Classification of omicron (B.1.1.529): SARS-CoV-2 variant of concern. Adults with a positive result whose SARS-CoV-2 test date was 14 days after the first dose of a 2-dose series but <14 days after receipt of the second dose were considered partially vaccinated. Urban Health 83, 10411062 (2006). Finally, we conducted additional supplemental analyses to estimate VE among children whose mothers received at least one vaccine dose prior to pregnancy onset and at least one dose during pregnancy. wrote the initial manuscript. Real-world data suggest lower COVID-19 vaccine effectiveness against Omicron variants11,12,13,14. supervised chart reviews. IMV status was missing in 1.4% (weighted) of hospitalizations; these hospitalizations are otherwise included elsewhere in the analysis. Cite this article. PubMed Central The average death rate among Americans over age 65 who contract the flu has ranged between 1 in 75 and 1 in 160 in recent years, according to the C.D.C. TN, NMF, SFlax, SFunk, SA, SB, and ST did the formal analysis. 41, e81e86 (2022). Adults who received booster doses were classified as those who completed their primary vaccination series and received an additional or booster dose of vaccine on or after August 13, 2021, at any time after the completion of their primary series, and 14 days before a positive test result for SARS-CoV-2, because COVID-19associated hospitalizations are a lagging indicator, and time passed after receipt of a booster dose has been shown to be associated with reduced rates of COVID-19 infection (https://www.nejm.org/doi/full/10.1056/NEJMoa2114255). COVID-19 incidence and death rates among unvaccinated and fully vaccinated adults with and without booster doses during periods of Delta and Omicron variant emergence25 U.S. Jurisdictions, April 4December 25, 2021.

Receipt of one dose especially during the third trimester was also associated with a reduced risk of infants testing positive for SARS-CoV-2 during the first 6 months of life during the Delta dominant period. Iowa did not provide immunization data but is included in the overall population-based hospitalization rates. The second study, led by Office for National Statistics researchers in Wales, involved death rates and risk factors in adults in England who had received an mRNA booster at least 14 days before Dec 31, 2021. Characteristics and maternal and birth outcomes of hospitalized pregnant women with laboratory-confirmed COVID-19COVID-NET, 13 states, March 1August 22, 2020. During the Omicron-predominant period, peak hospitalization rates among non-Hispanic Black (Black) adults were nearly four times the rate of non-Hispanic White (White) adults and was the highest rate observed among any racial and ethnic group during the pandemic. In King County, Wash., which includes Seattle, unvaccinated people were 13 times more likely to be hospitalized for coronavirus since December than people who were fully vaccinated.

All adults should stay up to date (1) with COVID-19 vaccination to reduce their risk for COVID-19associated hospitalization. Foppa, I. M., Haber, M., Ferdinands, J. M. & Shay, D. K. The case test-negative design for studies of the effectiveness of influenza vaccine. All adults should stay up to date (1) with COVID-19 vaccination to reduce their risk for COVID-19associated hospitalization. In this design, we used Cox proportional hazards models with calendar days as the underlying scale to estimate hazard ratios and calculated vaccine effectiveness as 1 minus the hazard ratio. NEW YORK and MAINZ, GERMANY, March 1, 2023 Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today submitted an application to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of a booster (fourth) dose of the companies' Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine in children 6 months through 4 years of age (also referred to as under 5 years). The study provides evidence that a previous omicron infection in triple-vaccinated individuals provides high amounts of protection against BA.5 and BA.2 infections.
