US FLUBLOK label1 updated to incorporate new safety study in pregnant individuals New safety data involving more than 48,000 pregnant individuals published in American Journal of Obstetrics and Gynecology (AJOG) Global Reports Recombinant or inactivated flu vaccines are recommended by the U.S. Centers for Disease Control and Protection (CDC), Advisory Committee on Immunization Practices (ACIP) and American College of Obstetricians and Gynecologists (ACOG) for individuals who are or will become pregnant during flu season2,3,4 Sanofi is committed to the ongoing rigorous scientific study of flu vaccines in at-risk populations, including older patients, patients with comorbidities and pregnant individuals BRIDGEWATER, N.J., Oct. 16, 2024 /PRNewswire/ -- The U.S. Food and Drug Administration (FDA) has updated the label for FLUBLOK (Influenza Vaccine) to include data from a new safety study involving pregnant individuals 18 years and older, in time to inform those hoping to comply with U.S. Centers for Disease Control and Prevention (CDC) recommendations to receive their annual flu vaccine ideally before the end of October.4,5 The results from the study of more than 48,000 pregnant individuals across multiple flu seasons were recently published in American Journal of Obstetricians and Gynecologists (AJOG) Global Reports and demonstrate FLUBLOK safety is consistent with a standard-dose flu vaccine and pregnancy-related outcomes in the general population.1,5 Thomas Grenier Head of Vaccines, North America, Sanofi "Today, we're proud to announce an important update to our label for FLUBLOK, from one of Sanofi's largest flu vaccine safety studies ever done in pregnant individuals, an important at-risk population group for influenza. Here at Sanofi, we strive to bring immunizations to populations at various stages of life. This update is an example of our ambition to continue expanding the body of real-world evidence for our flu vaccines portfolio, grounded in robust efficacy data. We do this so that patients and healthcare providers can have the confidence to use our vaccines as an important preventative tool ahead of the influenza season." This study was a post-licensure, observational, retrospective safety surveillance study of 48,781 pregnant individuals, including those with chronic conditions.1 In the study, patients were immunized with either FLUBLOK Quadrivalent (30.7%; n=14,981) or with a comparator standard-dose quadrivalent inactivated influenza vaccine (67.3%; n=33,800) during the Northern Hemisphere influenza seasons 2018-2019 and 2019-2020.1 Immunization occurred within 28 days prior to pregnancy or during pregnancy.1 The efficacy of FLUBLOK (quadrivalent) is relevant to FLUBLOK (trivalent) because both vaccines are manufactured using the same process and have overlapping compositions.5 Results showed: FLUBLOK demonstrated no increased risk of pregnancy, birth or neonatal/infant outcomes when compared to a standard-dose flu vaccine and estimated pregnancy outcomes for the general population.1 The most frequently reported pregnancy outcomes in the FLUBLOK Quadrivalent and SD-IIV4 groups respectively were eclampsia/preeclampsia (8.4% in both cohorts), preterm labor (3.6% and 3.5%), spontaneous abortion (3.1% and 3.0%), congenital/fetal anomalies detected during pregnancy (2.4% in both cohorts), placental abruption (0.8% and 0.7%) and stillbirth/fetal death (0.4% and 0.5%).1 The most frequently reported birth and neonatal/infant outcomes in the FLUBLOK Quadrivalent and SD-IIV4 groups were small for gestational age (SGA) (8.8% and 8.7%), major congenital anomalies (7.7% in both cohorts), preterm birth (7.3% and 7.5%), low birth weight (LBW) (5.9% and 5.8%) and failure to thrive (1.0% and 1.1%), respectively.1 Per the CDC, pregnant and postpartum (up to two weeks after the end of pregnancy) individuals are at higher risk for severe illness and complications from flu, particularly during the second and third trimesters.4 The American College of Obstetricians and Gynecologists (ACOG) recommends full vaccination during pregnancy, as this is when the risk of severe illness is highest.3,4 The CDC, Advisory Committee on Immunization Practices (ACIP) and ACOG recommend that individuals who are or will become pregnant during flu season receive an inactivated or recombinant vaccine as soon as it is available, as pregnant persons with influenza may be at increased risk for adverse pregnancy outcomes, including preterm labor and delivery.2,3,4 With over 125 years of heritage in helping protect global public health, Sanofi is one of the world leaders in vaccines, helping to vaccinate more than 500 million people annually. As one of the largest providers of influenza vaccines to the United States with a wide range of options, Sanofi meets immunization needs across the lifespan, from children as young as six months of age through adults 65 years of age and older. Indication and Important Safety Information for FLUBLOK (Influenza Vaccine) What is FLUBLOK (Influenza Vaccine)? FLUBLOK is a vaccine indicated for immunization for the prevention of disease caused by influenza A and B strains represented by antigens contained in the vaccine. FLUBLOK is given to people 18 years of age and older. IMPORTANT SAFETY INFORMATION FOR FLUBLOK® (INFLUENZA VACCINE) FLUBLOK should not be given to anyone who has had a severe allergic reaction to any component of the vaccine. Tell your health care provider if you have ever had Guillain-Barré syndrome (severe muscle weakness) after a previous influenza vaccination. If FLUBLOK is given to people with a compromised immune system, including those receiving therapies that suppress the immune system, the immune response may be lower than expected. Vaccination with FLUBLOK may not protect all people who receive the vaccine. Fainting has occurred following vaccination with FLUBLOK. Procedures should be in place to avoid injury from fainting. In adults 18 through 64 years of age, the most common side effects were pain where you got the shot, headache, tiredness, and muscle pain. In adults 65 years of age and older, the most common side effects were pain where you got the shot, tiredness and headache. Other side effects may occur.

FRIDAY, Sept. 20, 2024 -- Influenza vaccination in successive pregnancies is not associated with increased risk for prespecified adverse perinatal outcomes, according to a study published online Sept. 19 in JAMA Network Open . Darios Getahun, M.D., Ph.D., M.P.H., from Kaiser Permanente Southern California in Pasadena, and colleagues conducted a retrospective cohort study involving individuals with at least two successive singleton live-birth pregnancies to examine the association between seasonal influenza vaccination across successive pregnancies and adverse perinatal outcomes. Data were included for 82,055 people with singleton pregnancies between Jan. 1, 2004, and Dec. 31, 2018. Overall, 54.7 percent of the participants had influenza vaccination in successive pregnancies. The researchers found that vaccination in successive pregnancies was not associated with increased risks for preeclampsia or eclampsia, placental abruption, fever, preterm birth, preterm premature rupture of membranes, chorioamnionitis, or small-for-gestational-age birth compared with individuals not vaccinated in both pregnancies. The observed associations were not modified by interpregnancy intervals or vaccine type. "The study findings support recommendations to vaccinate people during pregnancy regardless of the interval between any two successive pregnancies and the type of vaccination," the authors write. Several authors disclosed ties to the pharmaceutical industry. Abstract/Full Text Whatever your topic of interest, subscribe to our newsletters to get the best of Drugs.com in your inbox.

MONDAY, Sept. 16, 2024 -- A self-reported history of gestational hypertension is associated with cardiovascular disease (CVD) in postmenopausal women, according to a study presented at the annual meeting of the Menopause Society, held from Sept. 10 to 14 in Chicago. Marie Tan, from the Drexel University College of Medicine in Philadelphia, and colleagues surveyed 383 women presenting for mammogram screening to assess associations between a self-reported history of preeclampsia or eclampsia, gestational hypertension, and gestational diabetes with CVD outcomes in postmenopausal women. The researchers found that 10.3 percent of women reported a history of CVD, while 2.8 percent reported a history of preeclampsia or eclampsia, 2.1 percent had a history of gestational hypertension, and 3.6 percent had a history of gestational diabetes. There was an association between self-reported history of gestational hypertension and CVD. While a numerically higher prevalence of CVD was seen in women with preeclampsia or eclampsia or all three adverse pregnancy outcomes, these associations were not statistically significant. No association was seen between gestational diabetes and CVD. “Future research based on a larger sample size is needed to better understand the role adverse pregnancy outcomes may have in cardiovascular disease development and risk stratification," Tan said in a statement.
