mRNA #Covid-19 #vaccines

The Advisory Committee on Immunization Practices (ACIP) has issued interim recommendations for the use of Pfizer-BioNTech and Moderna COVID-19 vaccines for the prevention of coronavirus disease 2019 (COVID-19) in the United States. Both vaccines are lipid nanoparticle-formulated, nucleoside-modified mRNA vaccines encoding the prefusion spike glycoprotein of SARS-CoV-2, the virus that causes COVID-19. These interim CDC clinical considerations are informed by data submitted to the Food … Continue reading mRNA #Covid-19 #vaccines

A global survey of potential acceptance of a #COVID-19 vaccine

Several coronavirus disease 2019 (COVID-19) vaccines are currently in human trials. In June 2020, we surveyed 13,426 people in 19 countries to determine potential acceptance rates and factors influencing acceptance of a COVID-19 vaccine. Of these, 71.5% of participants reported that they would be very or somewhat likely to take a COVID-19 vaccine, and 61.4% reported that they would accept their employer’s recommendation to do … Continue reading A global survey of potential acceptance of a #COVID-19 vaccine

#IgA dominates the early neutralizing antibody response to #SARS-CoV-2

Abstract Humoral immune responses are typically characterized by primary IgM antibody responses followed by secondary antibody responses associated with immune memory and comprised of of IgG, IgA and IgE. Here we measured acute humoral responses to SARS-CoV-2, including the frequency of antibody-secreting cells and the presence of SARS-CoV-2-specific neutralizing antibodies in the serum, saliva and broncho-alveolar fluid of 159 patients with COVID-19. Early SARS-CoV-2-specific humoral … Continue reading #IgA dominates the early neutralizing antibody response to #SARS-CoV-2

An Immunomodulatory Therapeutic #Vaccine Targeting Oligomeric #Amyloid-β

Background:Aging is considered the most important risk factor for Alzheimer’s disease (AD). Recent research supports the theory that immunotherapy targeting the “oligomeric” forms of amyloid-β (Aβ) may halt the progression of AD. However, previous clinical trial of the vaccine against Aβ, called AN1792, was suspended due to cases of meningoencephalitis in patients. Objective:To develop a peptide sensitized dendritic cells (DCs) vaccine that would target oligomer … Continue reading An Immunomodulatory Therapeutic #Vaccine Targeting Oligomeric #Amyloid-β

Association of postoperative #influenza vaccine on overall mortality in patients undergoing curative surgery for solid #tumors

Recent findings have found that the influenza vaccine induces changes in the immune system in favor of anti‐tumor cytotoxicity. The aim in this study was to investigate if an influenza vaccine given in the postoperative period decreased overall and cancer‐specific mortality in patients undergoing curative surgery for solid cancers. We conducted a registry‐based national observational study in Denmark in the period January 1, 2010 to … Continue reading Association of postoperative #influenza vaccine on overall mortality in patients undergoing curative surgery for solid #tumors

Prevention of #tuberculosis in macaques after intravenous BCG immunization

Mycobacterium tuberculosis (Mtb) is the leading cause of death from infection worldwide. The only available vaccine, BCG (Bacillus Calmette–Guérin), is given intradermally and has variable efficacy against pulmonary tuberculosis, the major cause of mortality and disease transmission. Here we show that intravenous administration of BCG profoundly alters the protective outcome of Mtb challenge in non-human primates (Macaca mulatta). Compared with intradermal or aerosol delivery, intravenous … Continue reading Prevention of #tuberculosis in macaques after intravenous BCG immunization

Association Between #Rotavirus Vaccination and Risk of #Intussusception Among Neonates and Infants

Twenty cases of definite intussusception were diagnosed within 31 days after rotavirus vaccination, with 11 cases (55%) in the vaccine group and 9 cases (45%) in the placebo group (RD, 0.17 per 10 000 infants [95% CI, −1.16 to 1.50 per 10 000 infants], P = .80; RR, 1.14 [95% CI, 0.49 to 2.64], P = .77). Seventy-four cases were reported within 1 year, with 37 cases (50%) in the vaccine … Continue reading Association Between #Rotavirus Vaccination and Risk of #Intussusception Among Neonates and Infants
