COVID-19

Within a 12-month time frame, adjusted vaccine effectiveness against diagnosed long and probable long COVID was 41.7% and 35.4%, respectively.

A new study found that a universal coronavirus vaccine would be cost saving as long as it had an efficacy and coverage of 10% or more.

A new study found that SARS-CoV-2 RNA was correlated with incident COVID-19 cases at the school level.

Study authors noted that intranasal vaccine delivery could offer benefits such as needle-free administration and induction of mucosal immunity.

A new study found that 16.1% of patients treated with nirmatrelvir-ritonavir (Paxlovid) reported long COVID symptoms, compared to 14% of untreated patients.

In response to a surge in cases of COVID-19, flu, and RSV, hospitals are reinstating mask guidelines to avoid adverse capacity outcomes and staffing shortages seen in prior years.

Although the study identified an increase in chronic symptoms among children that developed post-COVID-19 condition, the chance of initial development was low.

Although vaccination proves effective against severe infections, its impact on respiratory function in mild cases remains uncertain, particularly among health care workers.

Study authors theorized that the reduced effect could be due to disease-related or immunosuppressive treatment factors.

Patients hospitalized for either virus had an increased risk of death, hospital readmission, and health problems in multiple organ systems over 18 months of follow-up.

Immunizations against influenza, COVID-19, and RSV are lower than they were this time last year, and hospitalizations have increased across all age groups.

While either vaccine offers some protection, having both vaccines offers the strongest level of protection against hospitalization and severe complications like MIS-C, and death.

A Q&A with Robert Walker, MD, senior vice president and chief medical officer at Novavax.

Vaccinated study participants experienced fewer and less persistent symptoms, as well as fewer work hours lost, compared to unvaccinated participants.

A new study found that models that included wastewater data were 15% more accurate when compared to models that only included clinical case data.

Rich in polyphenolic compounds like chlorogenic acid (CGA), coffee may help ward off COVID-19 infection in the post-pandemic era.

Nirmatrelvir-ritonavir (Paxlovid) is an oral antiviral that inhibits the main protease of SARS-CoV-2 and is widely used in the United States.

The test is also the first OTC rapid antigen test cleared for any infectious disease.

Vaccine manufacturers, including Novavax, are still hard at work updating immunizations against a mutating SARS-CoV-2 virus.

The antiviral combination nirmatrelvir-ritonavir (Paxlovid) used for early symptoms of COVID-19 offers limited protection against the development of Long COVID.

Despite its aim to reduce in-person visits, a virtual urgent care (VUC) program in Ontario, Canada found that patients seen by a VUC provider with no further referral were more likely to visit the emergency room than those who came directly to the department.

The FDA is advising health care professionals who administer the vaccine to make sure the correct volume of the vaccine is withdrawn from the vial and the correct dose is administered to the patient.

Although long COVID has emerged as a major public health concern, it has not yet been clearly identified as a clinical condition.

A poster session at the 2023 American Academy of Pediatrics National Conference & Exhibition, featured a complex pediatric case involving SARS-CoV-2, bacterial coinfection, multiorgan failure, thrombotic microangiopathy, and systemic hyperinflammation.

The combination vaccine produced robust immune responses from vaccine candidates in a phase 1/2 clinical trial.
