Our additional supplemental analysis suggests that pregnant persons who received at least one vaccine dose before pregnancy should complete their vaccination series during pregnancy to provide protection to their children during the first 6 months of life.

This is a relevant consideration because vaccines can be less effective in persons with a weakened immune system. Morb. Monthly incidence is based on SARS-CoV-2 positive test result date or, if not known, hospital admission date. New federal data shows adults who received the updated shots cut their risk of being hospitalized with . 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. Marks, K. J. et al. J. "The association between the QCovid risk groups and the risk of death were stronger in people who had received a booster and were infected by the Omicron variant compared with evidence from the Alpha and Delta period in doubly vaccinated individuals," the authors wrote.

Sect. Child hospitalization rates reach record highs amid Omicron's surge DOI: http://dx.doi.org/10.15585/mmwr.mm7112e2. 387, 187189 (2022). Slider with three articles shown per slide. 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. SGN, HHW, NA, WH, MK, PB, AZ, JLB, MC, NAA, KH, RH, AC, GD, and ST curated the data. These findings are consistent with the diminishing of pregnancy-derived antibodies in infants over time22. Abbreviation: COVID-NET = COVID-19Associated Hospitalization Surveillance Network. Iowa did not provide immunization data but is included in the overall population-based hospitalization rates. J. 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). Gordon, N. & Lin, T. The Kaiser Permanente Northern California adult member health survey. IMV status was missing in 1.4% (weighted) of hospitalizations; these hospitalizations are otherwise included elsewhere in the analysis.

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. Hospitalization of infants and children aged 0-4 years with laboratory-confirmed COVID-19COVID-NET, 14 states, March 2020-February 2022. During the Omicron dominant period, receipt of 2 doses during pregnancy reduced the risk of the infant testing SARS-CoV-2 positive by 21% (95% CI: 21, 48) during the first 2 months of life, 14% (95% CI: 8, 32) during the first 4 months of life, and 13% (95% CI: 3, 26) during the first 6 months of life (Table2). 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).

Most QCovid risk groups were tied to an increased risk of post-booster death, except congenital heart disease, asthma, and previous fracture. The stats are for COVID-associated hospitalizations, which may include people for whom COVID-19 was not the primary reason for admission. Article MMWR and Morbidity and Mortality Weekly Report are service marks of the U.S. Department of Health and Human Services. ISSN 2041-1723 (online). Google Scholar. Three recent epidemiological studies found that vaccination during pregnancy was associated with a reduced risk of SARS-CoV-2 infection in infants during their first 4 months of life and a reduced risk of hospitalization during the first 5 months of life17,18,19. Nat Commun 14, 894 (2023). Vaccine 35, 58505857 (2017). https://www.cdc.gov/nchs/nvss/bridged_race.htm, ** https://www.medrxiv.org/content/10.1101/2021.08.27.21262356v1, On August 13, 2021, CDCs Advisory Committee on Immunization Practices (ACIP) issued the first of several recommendations for additional or booster doses of COVID-19 vaccine. SARS-CoV-2 infections can result in COVID-19associated hospitalizations, even among vaccinated persons. Mountain lions, a bobcat, red foxes, black bears, and skunks represent the latest avian flu cases in mammals. Although the study was unable to directly estimate VE against hospitalization due to the small number of hospitalized cases, it found that over the entire study period, the incidence rate of hospitalization during the first 6 months of life was much lower among the infants whose mothers were vaccinated during pregnancy compared with those whose mothers were not vaccinated. Risk was especially high for people with severe combined immunodeficiency (HR, 6.2). O.Z. mmwrq@cdc.gov. 4% of cases) without NHS numbers were excluded from our primary analysis. wrote the initial manuscript. E. & Klein, N. P. Effectiveness of vaccination during pregnancy to prevent infant pertussis. Hospitalisation associated with SARS-CoV-2 delta variant in Denmark. Adults with no documented receipt of any COVID-19 vaccine dose before the test date were considered unvaccinated. 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). Risk of hospital admission for patients with SARS-CoV-2 variant B.1.1.7: cohort analysis. The study did not adjust for maternal SARS-CoV-2 infections during pregnancy due to the inability of capturing home testing results. NHS Test and Trace statistics (England): methodology.

Hospitalizations rates increased among all adults irrespective of vaccination status (unvaccinated, primary series only, or primary series plus a booster or additional dose). Risk of hospitalization and vaccine effectiveness among COVID-19 New charts from the Centers for Disease Control and Prevention (CDC), more severe disease and more hospitalizations, Insider's Catherine Schuster Bruce reported.

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). COVID-19 hospitalization rates per 100,000 population by age and vaccination status, January 05 to February 01, 2023 Age group Age-specific rate per 100,000 among unvaccinated individuals Age-specific rate per 100,000 among those who received at least one booster dose Likelihood of unvaccinated individuals being hospitalized with Graff, K. et al. Weekly / March 25, 2022 / 71(12);466473. and statistical significance was assessed at two-sided p0.05. Carlsen, E. O. et al. A recent study found that the mean titer of maternally derived antibodies in infants of vaccinated mothers were higher at age 2 months compared with antibody titers at age 6 months23. Wkly. All these results were similar to those when no adjustments for covariates are made (Supplemental Table1). All adults should stay up to date with COVID-19 vaccination to reduce their risk for COVID-19associated hospitalization. Table 2. TN and NMF validated the data. COVID-19 vaccine surveillance report: week 6. URL addresses listed in MMWR were current as of Partially vaccinated adults, and those who received a single dose of a 1-dose product <14 days before the positive SARS-CoV-2 test result were not included in analyses by vaccination status but were included in rates and overall proportions that were not stratified by vaccination status. Although all data used in this analysis were anonymised, the individual-level nature of the data used risks individuals being identified, or being able to self-identify, if the data are released publicly. All information these cookies collect is aggregated and therefore anonymous. 1.04-1.49) after adjusting for age, sex, and vaccine characteristics. Comparative analysis of the risks of hospitalisation and death While this proportion might not be representative of the proportion of vaccinated pregnant women within KPNC because of our exclusion criteria, more efforts are needed to promote COVID-19 vaccines for pregnant persons because vaccination provides protection to mothers and their infants until they are old enough to receive their own COVID-19 vaccines.
