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%… Continue reading A global survey of potential acceptance of a #COVID-19 vaccine
#COVID-19 #Symptoms: Longitudinal Evolution and Persistence in Outpatient Settings
..Discussion: Coronavirus disease 2019 can persist and result in prolonged illness. Our study shows persistence of symptoms in a third of ambulatory patients 30 to 45 days after diagnosis even if we assume that those lost to follow-up were all asymptomatic. Fatigue, dyspnea, and loss of taste or smell were the main persistent symptoms. These… Continue reading #COVID-19 #Symptoms: Longitudinal Evolution and Persistence in Outpatient Settings
#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… Continue reading #IgA dominates the early neutralizing antibody response to #SARS-CoV-2
Effects of #probiotics on gut #microbiota: mechanisms of intestinal immunomodulation and neuromodulation
Recent explorations of the human gut microbiota suggest that perturbations of microbial communities may increase predisposition to different disease phenotypes. Dietary nutrients may be converted into metabolites by intestinal microbes that serve as biologically active molecules affecting regulatory functions in the host. Probiotics may restore the composition of the gut microbiome and introduce beneficial functions… Continue reading Effects of #probiotics on gut #microbiota: mechanisms of intestinal immunomodulation and neuromodulation
UK probes whether #COVID-19 vaccine caused #allergic reactions
LONDON (AP) — Britain’s medical regulator warned Wednesday that people with a history of serious allergic reactions shouldn’t get the COVID-19 vaccine from Pfizer and BioNTech, and investigators looked into whether two reactions on the first day of the U.K.’s vaccination program were linked to the shot. The advice was issued on a “precautionary basis,”… Continue reading UK probes whether #COVID-19 vaccine caused #allergic reactions
Post-lockdown SARS- #CoV-2 nucleic acid screening in nearly ten million residents of Wuhan, China
Stringent COVID-19 control measures were imposed in Wuhan between January 23 and April 8, 2020. Estimates of the prevalence of infection following the release of restrictions could inform post-lockdown pandemic management. Here, we describe a city-wide SARS-CoV-2 nucleic acid screening programme between May 14 and June 1, 2020 in Wuhan. All city residents aged six… Continue reading Post-lockdown SARS- #CoV-2 nucleic acid screening in nearly ten million residents of Wuhan, China
