Immunocompromised People May Not Produce Enough Protective Antibodies Against RSV After Vaccination
This study demonstrated heterogeneous antibody response to respiratory syncytial virus (RSV) vaccines among immunocompromised persons. In contrast to universal seroconversion and preF IgG fold rises greater than 10 in immunocompetent... read more
Anticipating the Future of the COVID-19 Pandemic
The initial instance of a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection was observed in December 2019 in the city of Wuhan, China. Subsequently, the virus disseminated expeditiously across the globe,... read more
Clinical Outcomes in Critically Ill COVID-19 Unvaccinated Patients Admitted to the ICU
We analyzed unvaccinated critically ill ICU patients with COVID-19 and interpreted their demographics, clinical characteristics, comorbidities, and laboratory data upon ICU admission for a better understanding of their impact... read more
Estimating Seroprevalence of COVID-19 Infection After Omicron Outbreak
This study aimed to investigate the seroprevalence of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) antibodies among individuals aged 18 years and older. Population-based study was conducted within the Arizona... read more
Increased Risk of Hospitalization in Celiac Disease with COVID-19 Infection Is Mitigated by Vaccination
Celiac disease (CD) patients with COVID-19 have a higher risk of hospitalization compared with non-CD referents. This risk is mitigated by vaccination in CD patients as it is in non-CD referents. ICU requirement occurred... read more
Myocarditis After COVID‐19 mRNA Vaccination in Australia
Myocarditis in adolescents and young adults following the administration of coronavirus disease 2019 (COVID‐19) mRNA vaccines has been reported. Vaccination of 12–16‐year‐old adolescents with Comirnaty (tozinameran,... read more
Myopericarditis Following COVID-19 Vaccination and Non-COVID-19 Vaccination
The overall incidence of myopericarditis from 22 studies (405,272,721 vaccine doses) was 33·3 cases (95% CI 15·3–72·6) per million vaccine doses, and did not differ significantly between people who received COVID-19... read more
Comparative analysis of the risks of hospitalisation and death associated with COVID-19 variants in England
The risk of severe outcomes following SARS-CoV-2 infection is substantially lower for omicron than for delta, with higher reductions for more severe endpoints and significant variation with age. Underlying the observed risks... read more
Ethnic Differences in COVID-19 Mortality in the 2nd and 3rd Waves of the Pandemic in England
Public health strategies to increase vaccination uptake in ethnic minority groups could reduce disparities in COVID-19 mortality that cannot be accounted for by pre-existing risk factors. Age-adjusted HRs of death involving... read more
Risk Factors for Severe COVID-19 Outcomes Among Adults Who Completed a Primary COVID-19 Vaccination
In this analysis of data from 465 U.S. health care facilities, severe COVID-19 outcomes (i.e., respiratory failure, ICU admission, or death) were rare among adults aged ≥18 years after primary vaccination. These findings... read more
Healthcare Worker Safety and COVID-19
It had been apparent from the start of the pandemic that both patients and healthcare workers are at significant risk of acquiring COVID-19 in hospitals. In an early report from Wuhan more than 40% of infections were hospital-acquired,... read more
Identification of Biomarkers, New Treatments, and Vaccines for COVID-19
The novel coronavirus 2019 (COVID-19) has caused a serious global pandemic in just one year. Nearly every country and territory in the world has been affected by the virus. The virulence and infection rate of the virus are... read more
Risk Factors for Severe COVID-19 in Children
Results identify children at potentially higher risk of severe disease who may benefit from COVID-19 prevention efforts, including vaccination. Rates of severe COVID-19 establish a baseline for monitoring changes in pediatric... read more
How protein-based COVID vaccines could change the pandemic
Unlike the relatively new technologies that the mRNA and viral-vector COVID-19 shots are based on, protein vaccines have been used for decades to protect people from hepatitis, shingles and other viral infections. To... read more
Not all COVID waves look the same. Here’s a snapshot of the Delta surge
Waves of Covid can give you an awful sense of déjà vu. As "Hot Vax Summer" gave way early to Delta-anxious fall, you could be forgiven for feeling a familiar sense of dread, not so different from what you’d felt before... read more
HIV and COVID-19 Increased Risk of Severe Outcomes
People living with HIV with detectable HIV viraemia, chronic comorbidities, and some subpopulations could be at increased risk of severe outcomes from COVID-19. These groups should be prioritised in clinical management and... read more
COVID-19-related Death in Fully Vaccinated People in Scotland – Characteristics and Risk
Vaccines are highly effective in preventing COVID-19 hospitalisations and deaths. COVID-19-related deaths in fully vaccinated individuals have, however, been reported. To inform public health strategy and vaccination... read more
Suboptimal COVID-19 Vaccination Coverage Implications in Florida and Texas
In July, 2021, another wave of COVID-19 began in the USA as the highly infectious delta (B.1.617.2) SARS-CoV-2 variant drove outbreaks predominantly affecting states with relatively low vaccination coverage. Some US states... read more
COVID-19 Immune Evasion by the B.1.427/B.1.429 Variant of Concern
As battles to contain the COVID-19 pandemic continue, attention is focused on emerging variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that have been deemed variants of concern because they... read more
Full Vaccination Suppresses COVID-19 Delta Variant Mutation Frequency
This study presents the first evidence that full vaccination against COVID-19 suppresses emergent mutations of SARS-CoV-2 delta variants. An evolution algorithm, Tajima's D test with a threshold value as -2.50, can provide... read more
Junior Doctors Write to Young People to Acknowledge Vaccine Concerns
A group of junior doctors from Scotland have written to young people in their age group to try to ease concerns they may have about receiving the covid-19 vaccine. In an open letter sent on Friday 6 August the doctors,... read more
