The COVID-19 pandemic continues to adversely affect the U.S., which leads globally in total cases and deaths. As vaccines are under development, public health officials policymakers need create strategic vaccine-acceptance messaging effectively control prevent thousands of additional deaths.Using an online platform, we surveyed U.S. adult population May 2020 understand risk perceptions about pandemic, acceptance a vaccine, trust sources information. These factors were compared across basic...
There is increasing evidence that coronavirus disease 2019 (COVID-19) produces more severe symptoms and higher mortality among men than women1–5. However, whether immune responses against acute respiratory syndrome (SARS-CoV-2) differ between sexes, such differences correlate with the sex difference in course of COVID-19, currently unknown. Here we examined viral loads, SARS-CoV-2-specific antibody titres, plasma cytokines blood-cell phenotyping patients moderate COVID-19 who had not...
Young infants and pregnant women are at increased risk for serious consequences of influenza infection. Inactivated vaccine is recommended but not licensed younger than 6 months age. We assessed the clinical effectiveness inactivated administered during pregnancy in Bangladesh.In this randomized study, we assigned 340 mothers to receive either (influenza-vaccine group) or 23-valent pneumococcal polysaccharide (control group). Mothers were interviewed weekly assess illnesses until 24 weeks...
Abstract Widespread acceptance of COVID-19 vaccines is crucial for achieving sufficient immunization coverage to end the global pandemic, yet few studies have investigated vaccination attitudes in lower-income countries, where large-scale just beginning. We analyze vaccine across 15 survey samples covering 10 low- and middle-income countries (LMICs) Asia, Africa South America, Russia (an upper-middle-income country) United States, including a total 44,260 individuals. find considerably...
Vaccines are among the most effective prevention tools available to clinicians. However, success of an immunization program depends on high rates acceptance and coverage. There is evidence increase in vaccine refusal United States geographic clustering refusals that results outbreaks. Children with exemptions from school requirements (a measure refusal) at increased risk for measles pertussis can infect others who too young be vaccinated, cannot vaccinated medical reasons, or were but did...
The rate of nonmedical exemptions to school immunization requirements has been increasing, and children with have contributed outbreaks vaccine-preventable diseases.To determine why parents claim explore differences in perceptions vaccines vaccine information sources between exempt fully vaccinated children.Case-control study.Colorado, Massachusetts, Missouri, Washington.Surveys were mailed the 815 (cases) 1630 (controls randomly selected from same grade school) recruited 112 private public...
Abstract Post-acute infection syndromes may develop after acute viral disease 1 . Infection with SARS-CoV-2 can result in the development of a post-acute syndrome known as long COVID. Individuals COVID frequently report unremitting fatigue, post-exertional malaise, and variety cognitive autonomic dysfunctions 2–4 However, biological processes that are associated persistence these symptoms unclear. Here 275 individuals or without were enrolled cross-sectional study included multidimensional...
School immunization requirements have played a major role in controlling vaccine-preventable diseases the United States. Most states offer nonmedical exemptions to school (religious or personal belief). Exemptors are at increased risk of acquiring and transmitting disease. The exemption policies may be especially important for pertussis, which is endemic States.To determine if (1) rates differ been increasing that only religious vs belief exemptions; (2) easy medium difficult processes...
The recent emergence of the SARS-CoV-2 Omicron variant is raising concerns because its increased transmissibility and numerous spike mutations, which have potential to evade neutralizing antibodies elicited by COVID-19 vaccines. Here we evaluated effects a heterologous BNT162b2 mRNA vaccine booster on humoral immunity participants who had received two-dose regimen CoronaVac, an inactivated used globally. We found that CoronaVac prime vaccination two doses followed induces elevated...
School immunization requirements are important in controlling vaccine-preventable diseases the United States. Forty-eight states offer nonmedical exemptions to school requirements. Children with at increased risk of contracting and transmitting diseases. The clustering can affect community authors evaluated spatial Michigan geographic overlap between clusters reported pertussis cases. Kulldorf's scan statistic identified 23 statistically significant census tract for exemption rates 6 cases...
Abstract Rapid and accurate SARS-CoV-2 diagnostic testing is essential for controlling the ongoing COVID-19 pandemic. The current gold standard diagnosis real-time RT-PCR detection of from nasopharyngeal swabs. Low sensitivity, exposure risks to healthcare workers, global shortages swabs personal protective equipment, however, necessitate validation new approaches. Saliva a promising candidate diagnostics because (1) collection minimally invasive can reliably be self-administered (2) saliva...
Infections during pregnancy have the potential to adversely impact birth outcomes. We evaluated association between receipt of inactivated influenza vaccine and prematurity small for gestational age (SGA) births.We conducted a cohort analysis surveillance data from Georgia (United States) Pregnancy Risk Assessment Monitoring System. Among 4,326 live births 1 June 2004 30 September 2006, maternal information was available 4,168 (96.3%). The primary intervention in this study any trimester...
