Even low levels of air pollution make COVID-19 worse, this study found. Air pollution exposure was associated with more severe disease, longer hospitalization periods, and an increased likelihood of intensive care admission.

The vaccine manufacturer has incorporated spike proteins for the XBB.1.5 sublineage of SARS-CoV-2 for its mRNA-1273.815 COVID-19 vaccine.

While COVID-19 patients had a higher risk of venous thromboembolic disease compared to influenza and sepsis patients, the risk of other adverse outcomes was comparable.

ABNCoV2, a non-adjuvanted COVID-19 booster vaccine by Bavarian Nordic, demonstrates promising results in phase 2 trials. The vaccine generates strong immune responses, neutralizing multiple variants of concern, including Beta, Delta, and Omicron.

In a large observational study, significant information was obtained about protection against acute infection and disease severity in this age group.

This past weekend, vaccine scientist and physician Peter Hotez, MD, PhD, was stalked outside his home after facing online scrutiny from Twitter CEO Elon Musk and controversial podcaster Joe Rogan. His story is severe, but Hotez is far from the first health advocate to be harassed online since the COVID-19 pandemic.

The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) unanimously voted 2023-2024 COVID-19 vaccines should be updated to a monovalent XBB strain.

"It does take the immune system a while to build up antibodies and recover," said Madeline King-Patel, PharmD, BCIDP, "So you don't want to give the vaccines too close to each other, or you're not going to get the full benefits."

A new retrospective study found non-oxygen-dependent COVID-19 patients were more likely to experience this phenomenon if they were immunocompromised, receiving concomitant corticosteroids, or had comorbidities.

This study compares the mortality rates between Canada's public health care and the US private system, highlighting the complexities of pandemic response.

As the official COVID-19 emergency is declared over, our Editor-in-Chief Jason Gallagher, PharmD, FCCP, FIDP, FIDSA, BCPS, reflects on the public health response, the scientific successes, and the shortcomings that were experienced.

COVID-19 and CMV coinfection caused the premature aging of immune systems, leading to a greater risk of cardiovascular disease at an earlier age, the study authors said.

Following household COVID-19 transmissions for over 3 years, investigators found that 70.4% had a pediatric index case.

How does the diagnosis rate of mental health disorders after COVID-19 compare to that of other respiratory infections?

The FDA's decision to approve Abrysvo was based on data from a Phase 3 clinical trial, which demonstrated the RSV vaccine's efficacy, immunogenicity, and safety in adults aged 60 and older.

Neutralizing antibodies were initially lowest among Janssen vaccine recipients, but this all changed 6 months after vaccination.

European medical committee offers favorable opinion for people with all forms of renal impairment including those on dialysis.

Sleep as a shield: A new study reveals that sleeping well before COVID-19 infection reduces the risk of post–COVID-19 condition (long COVID).

Analysis of symptoms present six months or more after SARS-CoV-2 infection was used to develop a composite scoring framework for identifying postacute sequelae of SARS-CoV-2 infection (PASC) as a new condition.

The Omicron variant caused the most symptoms in pediatric patients. However, there were no differences in adverse outcomes by COVID-19 variant.

A large study of patients treated in the intensive care unit (ICU) demonstrates common genetic links that point to a potential reason for people progressing to life-threatening forms of the respiratory virus.

Accelerating bivalent booster vaccine campaigns for children could reduce pediatric hospitalizations and school absenteeism.

Anticoagulant treatment for 3 to 6 months was sufficient for the majority of COVID-19 patients with venous thromboembolism, the study authors found.

The recommendations look to increase usage of the antiviral and decrease the routine use of the recombinant IL-1 inhibitor for COVID-19 treatment.

Antifungal therapy was frequently initiated before essential diagnostic elements confirmed invasive fungal infections in critically ill COVID-19 patients.

COVID-19 patients treated with the monoclonal antibodies tixagevimab and cilgavimab had few hospitalizations but no deaths.

Although vaccine effectiveness against the Omicron variant drops rapidly over time, a booster dose bolsters protection levels.

This study determined the efficacy of face masks at reducing exhaled particles in children, as well as whether the type of activity affected the concentration and size of particles.

On the same day WHO Director-General Tedros Adhanom Ghebreyesus declared the end of the COVID-19 public health emergency, CDC Director Rochelle Walensky announced she will be stepping down at the end of June.

COVID-19 symptom or viral rebound in the absence of antiviral treatment is common, but the combination of symptom and viral relapse is rare.
