Am. Monthly COVID-19 hospitalization rates were 3.5 to 17.7 times higher in unvaccinated patients than in their vaccinated counterparts, regardless of whether they had received a booster. JAMA Netw Open 2021;4:e2130479. Ainslie, K. E. C., Shi, M., Haber, M. & Orenstein, W. A. Adults who completed a primary vaccination series were persons who had received the second dose of a 2-dose COVID-19 vaccination series or a single dose of a 1-dose product 14 days before a positive SARS-CoV-2 test associated with their hospitalization but received no booster or additional dose.

All these results were similar to those when no adjustments for covariates are made (Supplemental Table1). In this analysis, we estimated the odds ratio (OR) of vaccination of mothers of infants who tested positive for SARS-CoV-2 versus infants who tested negative using logistic regression models conditioned (stratified) on the calendar date of the test so that infants testing positive on a certain day were compared to infants testing negative on that same day. PubMed Central Infect. Objectives To develop and implement a scoring tool to identify COVID-19 patients that are at risk for severe illness during the Omicron wave. The rate among adults who received a primary series, but no booster or additional dose, was three times the rate among adults who received a booster or additional dose. However, vaccination during pregnancy was less effective at protecting infants against SARS-CoV-2 infection during the Omicron period. These findings are consistent with the diminishing of pregnancy-derived antibodies in infants over time22. Danino, D. et al. Zerbo, O. et al. All authors (O.Z., B.F., N.P.K., T.R., M.G., E.L., P.R., K.G., S.O., and E.L.) critically reviewed the manuscript and decided to proceed with publication. Vaccine effectiveness of cell-culture relative to egg-based inactivated influenza vaccine during the 2017-18 influenza season. Children born at Kaiser Permanente Northern California from December 15, 2020, through May 31, 2022. Children currently account for about 18.5% of reported COVID-19 cases in the United States1. SARS-CoV-2 infection can lead to severe illnesses and hospitalizations in children and infants2,3,4,5. Racial and ethnic disparities in rates of COVID-19associated hospitalization, intensive care unit admission, and in-hospital death in the United States from March 2020 to February 2021. 387, 109119 (2022). Vaccination status is not available for Iowa and cases from Iowa are excluded from analyses that examined vaccination status. J. Med. 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. As infants aged, protection provided by maternal vaccination decreased during both periods. If SARS-CoV-2 test date was missing, hospitalization admission date was used. All analyses were conducted using SAS software, v9.4. Efficacy and safety of the mRNA-1273 SARS-CoV-2 vaccine. B, Severe outcomes included hospitalization and death. Acosta AM, Garg S, Pham H, et al. Finally, the COVID-NET catchment areas include approximately 10% of the U.S. population; thus, these findings might not be nationally generalizable. IMV status was missing in 1.4% (weighted) of hospitalizations; these hospitalizations are otherwise included elsewhere in the analysis. We conducted secondary sensitivity analyses restricting the population to infants who received at least one SARS-CoV-2 PCR test. Article Among 829 adults hospitalized during the Omicron-predominant period, 49.4% were unvaccinated, compared with 69.5% during the Delta-predominant period (p<0.01). Monthly incidence is based on SARS-CoV-2 positive test result date or, if not known, hospital admission date. It is possible that this practice may have led to some misclassification of the outcome, and we were unable to assess whether this misclassification was differential between vaccinated and unvaccinated mothers.

The rate among adults who received a primary series, but no booster or additional dose (133.5), was three times the rate among adults who received a booster or additional dose (45.0). During the Omicron period, among children whose mothers received 1 dose before pregnancy and 1 dose during pregnancy, VE against infection was 46% (95% CI: 23, 77) during the first 2 months of life, 16% (95% CI: 28, 50) during the first 4 months of life and 3% (95% CI: 32, 36) during the first 6 months of life compared with children whose mothers were unvaccinated (Supplemental Table4). Google Scholar. Additional recommendations followed and data availability on booster-dose status varies by age because not all age groups were recommended by ACIP to receive booster doses at the same time. The results were published yesterday in JAMA Network Open. Structural changes in the brain may explain the persistent fatigue and neuropsychiatric complications tied to long COVID. 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. Hospitalization rates and characteristics of children aged <18 years hospitalized with laboratory-confirmed COVID-19COVID-NET, 14 States, March 1-July 25, 2020. J. Med. In conclusion, in this population-based cohort study, we found that infants born to mothers who received at least two doses of an mRNA COVID-19 vaccine during pregnancy were at lower risk of testing positive for SARS-CoV-2 and were at lower risk of hospitalization during the first 6 months of life compared with infants whose mothers were unvaccinated during pregnancy. Hospitalisation associated with SARS-CoV-2 delta variant in Denmark. 384, 403416 (2021). Evan J. Anderson reports grants from Pfizer, Merck, PaxVax, Micron, Sanofi-Pasteur, Janssen, MedImmune, and GlaxoSmithKline; personal fees from Pfizer, Medscape, Kentucky Bioprocessing, Inc., Sanofi-Pasteur, and Janssen, outside the submitted work; and institutional funding from the National Institutes of Health to conduct clinical trials of Moderna and Janssen COVID-19 vaccines. 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. Vaccination offers the best way to protect against COVID-19 and its complications. 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. This can lead to overestimates of first doses and underestimates of subsequent doses, and underestimates of hospitalization rates in persons who received additional or booster doses. We further classified vaccination status by the trimester within which the second dose or the unique dose (for those who received only one dose) was received. Open 5, e2233273 (2022). Taken together, these findings suggest that the increased risk for hospitalization among Black adults during the Omicron-predominant period might also be due, in part, to lower proportions of Black adults receiving both the primary vaccination series and booster doses. J., Fireman. By comparison, from two to 25 weeks after the second dose, protection against Omicron hospitalization was 64%, the UKHSA said. For infants, we included age, as a categorical time-changing variable in 30-day increments. The study had limitations worth noting. The findings in this report are subject to at least four limitations. PubMed Atlanta, GA: US Department of Health and Human Services, CDC; 2022. This was the highest age-adjusted weekly rate observed among any racial and ethnic group during the pandemic. Over the entire study period, the crude rate of hospitalization with a SARS-CoV-2 positive test was lower during the first 6 months of life among infants whose mothers received at least two doses of mRNA COVID-19 vaccines during pregnancy compared with infants whose mothers were unvaccinated during pregnancy (21/100,000 PY vs. 100/100,000 PY). Surveillance officers abstracted data on sampled patients from medical charts. CDC. Nursing home residents have been disproportionately affected by COVID-19; older age, comorbidities, and the congregate nature of nursing homes place residents at higher risk for infection and severe COVID-19-associated outcomes . Maternal vaccination with at least two doses reduced the infants risk of testing SARS-CoV-2 positive initially by 84% which decreased to 56% by 6 months of life in the Delta dominant period. 386, 15321546 (2022).

J. Med. [email protected]. MMWR Morb Mortal Wkly Rep 2022;71:1328. Experts say they. As Omicron spread in the US, hospitalization rates in December were much lower for the vaccinated. There were only one hospitalized case among the children of vaccinated mothers and nine hospitalized cases among the children of unvaccinated mothers (Table1). During the study period, the omicron variant experienced a rapidly increasing incidence, whereas the delta variant was experiencing a decreasing or less rapidly increasing incidence. Graff, K. et al. Using Cox regression, the effectiveness of 2 doses of COVID-19 vaccine received during pregnancy was 84% (95% confidence interval [CI]: 66, 93), 62% (CI: 39, 77) and 56% (CI: 34,71) during months 02, 04 and 0- 6 of a childs life, respectively, in the Delta variant period. During the Delta period, receipt of one dose during the third trimester reduced infants risk of testing positive for SARS-CoV-2 by 74% (95% CI: 19, 92) during the first 6 months of life (Table3). Frequency, characteristics and complications of COVID-19 in hospitalized infants. Defined as one or more of the following: chronic lung disease including asthma, chronic metabolic disease including diabetes mellitus, blood disorder/hemoglobinopathy, cardiovascular disease, neurologic disorder, immunocompromising condition, renal disease, gastrointestinal/liver disease, rheumatologic/autoimmune/inflammatory condition, obesity, feeding tube dependency, and wheelchair dependency. Omicron is super infectious, and about 20% of people in the United States over the age of 5 as well as all children under 5 remain unvaccinated. M.G. Nat Commun 14, 894 (2023). Sadoff, J. et al.

Female sex was a protective factor (HR, 0.52), while residence in a nursing home or low-income area was a risk factor. Sect. Hospitalizations rates increased among all adults irrespective of vaccination status (unvaccinated, primary series only, or primary series plus a booster or additional dose). Blakeway, H. et al. TN and NMF validated the data. "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. This correction ensures that there is always a reasonable denominator for the unvaccinated population that would prevent hospitalization rates from growing unrealistically large because of potential overestimates of vaccination coverage. Several conditions, including cancer of the blood or bone marrow and dementia, were associated with HRs greater than 3. These persons are excluded from the proportions of race/ethnicity but are included in other analyses.

Additional limitations include the inability to estimate the effectiveness of vaccines received prior to pregnancy onset. Mountain lions, a bobcat, red foxes, black bears, and skunks represent the latest avian flu cases in mammals. Methods: One hundred and . The group raised concerns about a small number of Guillain-Barre syndrome cases in vaccine recipients and wanted more data, especially on efficacy in those at highest risk. We examined the effectiveness of maternal vaccination against SARS-CoV-2 infection in 30,311 infants born at Kaiser Permanente Northern California from December 15, 2020, to May 31, 2022. Relative to the Delta-predominant period, the proportion of cases in non-Hispanic Asian or Pacific Islanders also increased, whereas the proportion in all other racial and ethnic groups decreased. 2022 The Authors.

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). Garg S, Patel K, Pham H, et al. Black adults accounted for a higher percentage of hospitalizations during the Omicron-predominant period (26.7%) than during the Delta-predominant period (22.2%, p = 0.05). 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. 9-14 As of October 2022, 68% of the US population has completed primary series vaccination.

Delahoy MJ, Whitaker M, OHalloran A, et al. Implementing strategies that result in the equitable receipt of COVID-19 vaccinations, though building vaccine confidence, raising awareness of the benefits of vaccination, and removing barriers to vaccination access among persons with disproportionately higher hospitalizations rates from COVID-19, including Black adults, is an urgent public health priority.

China informed the WHO about the case, which involves a 53-year-old woman, on Feb 24. From this cohort, the study excluded the following infants born to (1) mothers who were not between ages 16 and 50 years at pregnancy onset; (2) mothers who did not have a primary KPNC facility assignment; (3) mothers who were not continuous KPNC members from December 15, 2020 until delivery; (4) mothers who had a positive nasal/throat swab for SARS-CoV-2 by polymerase chain reaction (PCR) prior to pregnancy onset; (5) mothers who had a positive SARS-CoV-2 antibody test documented by KPNC prior to the onset of pregnancy; (6) mothers who received one or more doses of COVID-19 vaccine prior to pregnancy onset. Among these infants, for our main analysis, we excluded 21,891 (35.2%) based on maternal exclusion criteria and 10,412 (16.8%) after applying infant exclusion criteria (Fig. Open 5, e2232760 (2022). Andrews, N. et al. 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.
