A study from the U.K. government, published last week, found that three doses of vaccine. J. Pediatr. The average age of decedents was 83.3 years. VE against hospitalization was not estimated because of the very small number of hospitalized cases. 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). Among children 12 to 17, the . 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). Requests for access to the underlying source data should be directed to UKHSA. 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). SGN, HHW, NA, WH, MK, PB, AZ, JLB, MC, NAA, KH, RH, AC, GD, and ST curated the data. Perm. Delahoy MJ, Whitaker M, OHalloran A, et al. Our study was strengthened both by its large sample size and our ability to follow infants through 6 months of age. Hospitalization rates and characteristics of children aged <18 years hospitalized with laboratory-confirmed COVID-19COVID-NET, 14 States, March 1-July 25, 2020. 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. The remaining authors declare no competing interests. Selected counties in California, Colorado, Connecticut, Georgia, Iowa, Maryland, Michigan, Minnesota, New Mexico, New York, Ohio, Oregon, Tennessee, and Utah (https://www.cdc.gov/mmwr/volumes/69/wr/mm6915e3.htm). 40, e137e145 (2021).

Data from the COVID-19Associated Hospitalization Surveillance Network (COVID-NET) were analyzed to compare COVID-19associated hospitalization rates among adults aged 18 years during B.1.617.2 (Delta; July 1December 18, 2021) and Omicron (December 19, 2021January 31, 2022) variant predominance, overall and by race/ethnicity and vaccination status. Article of pages found at these sites. SARS-CoV-2 infection can lead to severe illnesses and hospitalizations in children and infants2,3,4,5. and/or the original MMWR paper copy for printable versions of official text, figures, and tables. Johnson AG, Amin AB, Ali AR, et al. Surveillance officers abstracted data on sampled patients from medical charts. All information these cookies collect is aggregated and therefore anonymous. We also conducted analyses based on the trimester during which the vaccine was received during pregnancy (first, second, or third trimester). During Omicron predominance, children aged <6 months accounted for 44% of hospitalizations among children ages 04 years3. Risk of hospitalisation associated with infection with SARS-CoV-2 lineage B.1.1.7 in Denmark: an observational cohort study. During the Delta dominant period, the crude incidences of testing positive for SARS-CoV-2 during the first 2, 4, and 6 months of life were lower among infants whose mothers received at least two doses of mRNA COVID-19 vaccines during pregnancy (0.75, 1.43, and 1.56 infants per 100 person-years [PY], respectively) than those whose mothers were not vaccinated during pregnancy (5.47, 5.10, and 4.78 infants per 100 PYs, respectively). Real-world data suggest lower COVID-19 vaccine effectiveness against Omicron variants11,12,13,14. B., Lewis. 3501 et seq. Additional limitations include the inability to estimate the effectiveness of vaccines received prior to pregnancy onset. Evaluation of acute adverse events after Covid-19 vaccination during pregnancy. Late last year, as Omicron was spreading fast in the US, hospitalization rates per 100,000 rose sharply among unvaccinated adults, while rates in those who were fully vaccinated remained. This conversion might result in character translation or format errors in the HTML version. The study did not adjust for maternal SARS-CoV-2 infections during pregnancy due to the inability of capturing home testing results. 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). KPNC has a comprehensive electronic health record system (Kaiser Permanente HealthConnect, a customized EPIC system), that captures detailed information on all medical services, including immunization, membership enrollment including place of residence, demographics, and pregnancy-related care from pregnancy onset to delivery, and beyond. The vaccines have proved highly safe and effective at reducing the risk of severe illness, hospitalization and death. By comparison, from two to 25 weeks after the second dose, protection against Omicron hospitalization was 64%, the UKHSA said. Google Scholar. COVID-19 vaccine surveillance report: week 6. Adults with no documented receipt of any COVID-19 vaccine dose before the test date were considered unvaccinated. No other potential conflicts of interest were disclosed. Two recent papers claim there are no differences between surgical masks and respirators for preventing the spread of respiratory diseases like COVID-19 and flu, but the articles are deeply flawed. We ran separate models on the time periods associated with the Delta (7/01/2021 to 12/20/2021) and Omicron variants (12/21/2021 to 5/31/2022).

BNT162b2 mRNA Covid-19 vaccine in a nationwide mass vaccination setting. By clicking Sign up, you agree to receive marketing emails from Insider It is possible that our exclusion criteria may have resulted in a final sample that may not be reflective of all KPNC infants. To ensure stability and reliability of rates by vaccination status, data are presented beginning when 14 days have passed since at least 5% of the population of adults aged 18 years in the COVID-NET surveillance catchment area had received an additional or booster dose. Risk of hospital admission for patients with SARS-CoV-2 variant B.1.1.7: cohort analysis. Schrag, S. J. et al. 26 Among those fully vaccinated individuals 5 years of age who are booster eligible, only 49% have received a . Article 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. However, vaccination during pregnancy was less effective at protecting infants against SARS-CoV-2 infection during the Omicron period. Although both approaches adjusted for the same confounding factors, the effectiveness estimates from the TND were higher than those from the cohort design, which is consistent with our previous analyses of influenza vaccine effectiveness in which we also observed that the TND tended to result in higher vaccine effectiveness estimates than did our cohort analyses30. 1CDC COVID-19 Emergency Response Team; 2General Dynamics Information Technology, Atlanta, Georgia; 3California Emerging Infections Program, Oakland, California; 4Career Epidemiology Field Officer Program, CDC; 5Colorado Department of Public Health & Environment; 6Connecticut Emerging Infections Program, Yale School of Public Health, New Haven, Connecticut; 7Emory University School of Medicine, Atlanta, Georgia; 8Georgia Emerging Infections Program, Georgia Department of Public Health; 9Atlanta Veterans Affairs Medical Center, Atlanta, Georgia; 10Iowa Department of Public Health; 11Michigan Department of Health and Human Services; 12Minnesota Department of Health; 13New Mexico Emerging Infections Program, University of New Mexico, Albuquerque, New Mexico; 14New York State Department of Health; 15University of Rochester School of Medicine and Dentistry, Rochester, New York; 16Ohio Department of Health; 17Public Health Division, Oregon Health Authority; 18Vanderbilt University Medical Center, Nashville, Tennessee; 19Utah Department of Health. In the TND, we estimated that during the Delta predominant period, maternal vaccination with at least doses reduced the infants risk of testing SARS-CoV-2 positive by 95% (95% CI:76, 99) during the first 2 months of life, 70% (95% CI: 52, 82) during the first 4 months of life, and 61% (95% CI: 42, 74) during the first 6 months of life (Supplemental Table2). Age was the most important risk factor for COVID-19 death (eg, HR, 31.3 for an 80-year-old vs a 50-year-old). 383, 26032615 (2020). Vaccine 31, 31043109 (2013). ; COVID-NET Surveillance Team. 385, 13551371 (2021). URL addresses listed in MMWR were current as of Vaccine 35, 58505857 (2017). All these results were similar to those when no adjustments for covariates are made (Supplemental Table1). Another explanation is the presence of a high COVID-19 vaccination rate among studied individuals (more than two-thirds), which is supported by the finding that the majority of patients had been infected with SARS-CoV-2 prior to undergoing vaccination.
