COVID-19 vaccination was effective in children, adolescents during 2021
A large study of U.S. children and teens who received the Pfizer/BioNTech COVID-19 vaccine finds that it was effective through much of 2021, but waned over time, especially as the omicron variant became dominant in 2022. Teens who received a booster dose regained some protection.
COVID-19 vaccination of mother during pregnancy protects infant, though protection wanes
Being vaccinated against COVID-19 during pregnancy provides protection for the baby through its first several months of life, a Kaiser Permanente analysis finds. Protection was stronger against the delta variant than the more recent omicron variant.
Shorter wait between COVID-19 and elective surgery possible
Kaiser Permanente researchers have good news for patients, surgeons, anesthesiologists, and hospital administrators who have had to put off elective surgery because of a positive COVID-19 test. Among fully vaccinated patients, there may not be an elevated risk with surgery soon after COVID-19.
COVID-19 patients did better if they had booster vaccination
A large Kaiser Permanente analysis of COVID-19 patients confirms the value of vaccination, finding higher rates of hospitalization and advanced medical care for COVID-19 patients who were unvaccinated, were vaccinated but not boosted, or who had an additional health condition such as obesity or heart disease.
Pandemic stressors taking a toll on pregnant patients’ mental health
Pregnant patients surveyed by Kaiser Permanente researchers early in the COVID-19 pandemic reported more severe mental health symptoms when they were distressed about changes in prenatal care, childcare challenges, and food insecurity. A second study found disparities in how Black and Hispanic pregnant individuals experienced pandemic stressors compared with white patients.
Coronavirus may double severe complications in pregnancy
A Kaiser Permanente analysis of pregnant patients who tested positive for the coronavirus found more than double the risk of poor outcomes including preterm birth, venous thromboembolism (blood clot), and severe maternal morbidity, which includes conditions such as acute respiratory distress syndrome and sepsis.
Early data on COVID-19 vaccine in teens shows booster effectiveness
An analysis of early data on the effectiveness of the Pfizer/BioNTech COVID-19 vaccine in children and teens found that a third shot, or booster, extended protection against emergency department and urgent care visits in 16- and 17-year-olds.
Kaiser Permanente researchers study pandemic pregnancies
Kaiser Permanente researchers are surveying pregnant women during the pandemic and the first findings from the survey show a low percentage of COVID-19 infections, with higher prevalence among younger women, Hispanic women, and those living in neighborhoods with greater economic deprivation.
Teen suicidal thoughts and behaviors during pandemic vary by gender, diagnosis
The number of teens being seen at Kaiser Permanente Northern California emergency departments (ED) for suicidal thoughts and behaviors did not increase significantly during the COVID-19 pandemic, though specific groups of teens may have sought care at higher rates during late 2020.
The findings were reported Sept. 1 in JAMA Psychiatry.
Analysis confirms racial disparities in COVID-19 infection
An analysis of Kaiser Permanente members in Northern California early in the COVID-19 pandemic found racial and ethnic disparities in the likelihood of testing positive for the coronavirus, but no significant disparities in mortality among those who were hospitalized.
COVID-19 antibody research to illuminate pandemic’s course in Northern California
Researchers with Kaiser Permanente are launching a study using blood tests for antibodies to the SARS-CoV-2 virus to estimate the prevalence and incidence of COVID-19 disease in Northern California and explore whether antibodies confer protection from recurrent disease.
Large decrease in hospitalized heart attack patients seen during COVID-19 pandemic
New research by Kaiser Permanente shows the weekly number of patients admitted to Kaiser Permanente Northern California hospitals with acute myocardial infarction (heart attacks) fell to nearly half of what would be expected after the onset of the COVID-19 pandemic.
Population-level estimates show wide age range of adults hospitalized with COVID-19
A JAMA study, using data on patients hospitalized in March from all 21 Kaiser Permanente Northern California hospitals, is one of the first U.S. studies to look at overall hospitalization admissions of COVID-19 patients.
