By the end of December, Omicron made up 58% of all cases in the US, per Our World in Data, but Delta is thought to cause more severe disease and more hospitalizations than Omicron on average. Mountain lions, a bobcat, red foxes, black bears, and skunks represent the latest avian flu cases in mammals. 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. Wkly Rep. 71, 352358 (2022). Department of Health and Human Services. J. Med. It showed that boosters further reduced the risk of hospitalization. NHS Test and Trace statistics (England): methodology. Without the vaccines many more people would likely be in hospital. supervised chart reviews. The exposure of interest was mRNA COVID-19 vaccination status during pregnancy in the electronic health record. The results were unchanged when no adjustments for covariates were made (Supplemental Table3). Second, vaccination status is subject to misclassification; this might affect estimation of rates by vaccination status. Maryland did not contribute data after December 4, 2021, but did contribute data for previous weeks. JAMA 326, 16291631 (2021). References to non-CDC sites on the Internet are COVID-19 vaccine surveillance report: week 6. We calculated VE as 100% multiplied by 1- OR. Among nonpregnant and pregnant adults aged 18 years, hospitalization rates were calculated overall, and by race/ethnicity and COVID-19 vaccination status. Cite this article.

On the bias of estimates of influenza vaccine effectiveness from test-negative studies. Gynecol. Receipt of COVID-19 vaccine during pregnancy and preterm or small-for-gestational-age at birtheight integrated Health Care Organizations, United States, December 15, 2020-July 22, 2021. New charts from the Centers for Disease Control and Prevention (CDC) showed that hospitalization rates were much lower among those who were vaccinated even as Omicron was sweeping the nation. Rep. 70, 895899 (2021). Vaccine 35, 58505857 (2017). All these results were similar to those when no adjustments for covariates are made (Supplemental Table1). Implementing strategies that result in the equitable receipt of COVID-19 vaccinations among persons with disproportionately higher hospitalizations rates, including non-Hispanic Black adults, is an urgent public health priority. Adults with no documented receipt of any COVID-19 vaccine dose before the test date were considered unvaccinated. 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. The risk of hospitalisation appeared to increase when comparing delta with alpha infections. Vaccines: The CDC recommends that everyone age 5 and older get an updated covid booster shot. **** ICU admission and IMV are not mutually exclusive categories, and patients could have received both. The University of Minnesota is an equal opportunity educator and employer, Office of the Vice President for Research | Contact U of M | Privacy Policy, Mary Van Beusekom | News Writer | CIDRAP News, 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. SARS-CoV-2 variants of concern and variants under investigation in England: technical briefing 35. We were not able to evaluate more detailed measures of relative clinical severity in hospitalised patients (such as intensive care unit admittance), but our finding that estimated severity reductions comparing omicron with delta are larger for more severe endpoints (death and hospital admission versus hospital attendance) agrees with observations that the proportion of hospitalised COVID-19 patients requiring intensive care or mechanical ventilation (or both) has been substantially lower during the omicron wave in England than the preceding delta wave. Several conditions, including cancer of the blood or bone marrow and dementia, were associated with HRs greater than 3. 385, 13551371 (2021). Evaluation of the relative virulence of novel SARS-CoV-2 variants: a retrospective cohort study in Ontario, Canada. The results were published yesterday in JAMA Network Open. provided as a service to MMWR readers and do not constitute or imply You can review and change the way we collect information below. Hobbs, C. V. et al. Hospitalization rates were 10.5 times higher in the unvaccinated and 2.5 times higher in vaccinated patients with no booster than in booster recipients. SGN, HHW, NA, WH, MK, PB, AZ, JLB, MC, NAA, KH, RH, AC, GD, and ST curated the data. 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). as well as other partner offers and accept our. * Adults who completed a primary vaccination series were defined as those who had received the second dose of a 2-dose primary 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 dose. Ainslie, K. E. C., Shi, M., Haber, M. & Orenstein, W. A. The stats are for COVID-associated hospitalizations, which may include people for whom COVID-19 was not the primary reason for admission. 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. The data cannot be shared publicly because the data contain potentially identifying or sensitive patient information and is legally restricted by Kaiser Permanente Northern California. Google Scholar. Because the immune status of all patients is not known, an additional dose (recommended for persons with a weakened immune system) cannot be distinguished from a booster dose. After the emergence of the Omicron variant, the rate of COVID-19 hospitalizations in the United States was 10.5 times higher in unvaccinated adults and 2.5 times higher in those who were vaccinated but received no booster than in booster recipients, according to a new study. From Jan 1 to Mar 16, 2022, when Omicron was predominant, 4,781 (0.02%) of 19,473,570 booster recipients died of COVID-19, and 58,020 (0.3%) died of other causes. 241(d); 5 U.S.C. After adjusting for covariates, vaccination during pregnancy significantly reduced the risk of the infant testing SARS-CoV-2 positive by 84% (95% confidence interval [CI]: 66, 93) during the first 2 months of life, 62% (95% CI: 39, 77) during the first 4 months of life and 56% (95% CI: 34,71) during the first 6 months of life. JAMA Netw. The TND analyses avoid this bias by limiting the analysis to infants who were tested for SARS-CoV-2. 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). Estimation of COVID-19 mRNA vaccine effectiveness against medically attended COVID-19 in pregnancy during periods of delta and Omicron variant predominance in the United States. The aim of the secondary design was to compare the results of the cohort with TND. Zerbo, O., Ray, G.T., Fireman, B. et al. Zerbo, O. et al. There was no link between risk of COVID-19 death and race, except for Indian patients, who were at slightly higher risk than their White peers. 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. PubMedGoogle Scholar. ; COVID-NET Surveillance Team. It is possible that our exclusion criteria may have resulted in a final sample that may not be reflective of all KPNC infants. Between December 15, 2020, and May 31, 2022, we identified 62,117 infants born at Kaiser Permanente Northern California (KPNC), an integrated healthcare delivery organization.

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. "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. 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).

Thus, this design better adjusts for healthcare-seeking behavior31,32, but it may also introduce other biases including selection bias33. Carlsen, E. O. et al. Dr. Klein reported receiving grants from Pfizer, Merck, GlaxoSmithKline, and Sanofi Pasteur. Weekly rates among unvaccinated adults and adults who received a primary COVID-19 vaccination series with a booster or additional dose peaked at 149.8 (January 8, 2022) and 11.7 (January 22, 2022), respectively. We, therefore, were unable to assess whether maternal infection provided some protection to their infants. 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. N. Engl. 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. Urban Health 83, 10411062 (2006). The findings in this report are subject to at least four limitations. Classification of omicron (B.1.1.529): SARS-CoV-2 variant of concern. Lipkind, H. S. et al.

Nature Communications thanks Annette Regan, Olof Stephansson and the other, anonymous, reviewer(s) for their contribution to the peer review of this work. Morb. 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. All adjustment variables were selected a priori based on prior work36. The U.K. Health. All adults should stay up to date (1) with COVID-19 vaccination to reduce their risk for COVID-19associated hospitalization. Infect. B, Severe outcomes included hospitalization and death. Wkly. However, a milder virus could still put pressure . Most hospitalized children were unvaccinated, and nearly one in three were Black. 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). Protection during both periods decreased as infants aged from 2 months to 6 months. J. COVID-19 vaccination coverage among pregnant women during pregnancyEight Integrated Health Care Organizations, United States, December 14, 2020-May 8, 2021.

These findings are consistent with estimates of booster effectiveness against symptomatic Omicron infection using healthcare ascertainment. 226, 236 e1236.e14 (2022). We monitored the seroprevalence of SARS-CoV-2 nucleocapsid (anti-N) and spike protein (anti-S) antibodies in blood donors across Canada from September 2021 to June 2022 in 202,123 . 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. Among the infants in the cohort, 19,418 (64.06%) of the mothers were unvaccinated during pregnancy, 1138 (3.75%) of the mothers received one dose of an mRNA COVID-19 vaccine and 9755 (32.18%) received 2 doses during pregnancy (Table1). adjudicated chart reviews. Health and Human Services. The efficacy of COVID 19 vaccines for reducing the risk of severe COVID-19 infection is demonstrated in real life. Thompson, M. G. et al.

Article TN, NMF, SFlax, SFunk, SA, SB, and ST did the formal analysis. Wkly. Abbreviations: COVID-NET = COVID-19Associated Hospitalization Surveillance Network; ICU=intensive care unit; IMV=invasive mechanical ventilation; LTCF=long-term care facility; NA = not applicable. 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. MMWR and Morbidity and Mortality Weekly Report are service marks of the U.S. Department of Health and Human Services. According to the Ontario Science Table's online dashboard, the hospital occupancy rate for the unvaccinated was 611 per million unvaccinated people in the province's population as of Jan. 7,. Most QCovid risk groups were tied to an increased risk of post-booster death, except congenital heart disease, asthma, and previous fracture. Vaccine effectiveness of cell-culture relative to egg-based inactivated influenza vaccine during the 2017-18 influenza season. It is not inevitable that viral evolution leads to lower severity. Individual and neighborhood factors associated with failure to vaccinate against influenza during pregnancy. Vaccination status is based on state immunization information system data. Kim, L. et al.

BNT162b2 mRNA Covid-19 vaccine in a nationwide mass vaccination setting. In this analysis, vaccine effectiveness was evaluated as 1 minus the odds ratio. Most mothers (1032 of 1138) who received only one dose received the vaccine during the third trimester. volume14, Articlenumber:894 (2023) On 13 December, Denmark released data showing that hospitalization rates for people infected with Omicron seemed to be on a par with those for people infected with other variants. Initial hospital data from England and Denmark also suggest Omicron cases are less severe.
