Researchers sought to assess antibiotic prescriptions associated with COVID-19 outpatient visits in Medicare beneficiary patients over the course of a year during the pandemic.

Historically low incidence of dengue in southeast Asia and Latin America linked to COVID-19 restrictions suggests potential future interventions.

Dr. Simon Portsmouth of Shionogi discusses the trial results of their once-daily oral COVID-19 antiviral, S-217622, as well as the significance of the therapy as vaccine efficacy wanes in the age of Omicron.

Correlating immune response to COVID-19 vaccination in persons with HIV to their CD4 T-cell count could inform optimal vaccine strategy.

PrEP prescription initiations and fills dropped during the early parts of the COVID-19 pandemic, according to investigators from the NY State Department of Health.

Utilization of ambulatory care services declined during the COVID-19 pandemic, especially among socioeconomically disadvantaged Americans.

Cancer increased risk of COVID-19 among the vaccinated, with subsequent "significant and substantial" hospitalizations and mortality.

Ensovibep, the COVID-19 antiviral treatment developed by Novartis and Molecular Partners, is facing delays in its quest for emergency authorization after the FDA indicated more study data is required.

If authorized, this would be the first vaccine applicable to the youngest pediatric group.

A recent study examined whether immune response to the Pfizer-BioNTech COVID-19 vaccine differed by age and gender.

Lasting 505 days, investigators documented the longest known COVID-19 infection. The research, presented at ECCMID, also found one of the first cases of occult COVID-19, in which a patient who tests negative is later found to have ongoing COVID-19.

An ECCMID study found COVID-19 primary infections were more severe than reinfections, and vaccination further reduced symptoms.

Immune escape for the BA.2 subvariant, or “stealth Omicron,” was not as severe as that of the original Omicron variant, a new study suggests.

The supplemental new drug application is expanded to include the youngest COVID-19 patients.

During the pandemic, antibiotic-resistant bacterial infections increased in hospitalized patients who tested positive or negative for COVID-19.

One study, presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), found waiting longer in between the first and second Pfizer-BioNTech vaccine doses boosted immune response 9-fold.

Investigators used electronic health records (EHR) to perform surveillance of the safety of 3 doses of the COVID-19 mRNA vaccines.

The pandemic offered valuable lessons on improving the translation of evidence to practice, according to a recent survey of academic medical centers.

Today at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), Shionogi presented late-breaking data from their phase 2/3 clinical trial for S-217622, an investigational 3CL protease inhibitor. On day 4 of treatment with Shionogi’s S-217622, COVID-19 positive viral titers decreased by 90%.

A group of over 60 scientists participated in a communication to the federal agency to advocate for measuring these cells in COVID-19 vaccine trials.

The World Health Organization (WHO) has strongly recommended nirmatrelvir and ritonavir (Paxlovid), as well as remdesivir, for COVID-19 treatment. WHO emphasized that these medicines should be made accessible to low- and middle-income countries.

Investigators consider the low rate of vaccination in the rapidly increasing migrant populations in Europe, and call for improved strategies.

Pediatric intensive care unit (PICU) hospitalizations were 41% lower than expected during the outbreak of COVID-19.

The investigational vaccine's findings from their phase 1/2 clinical trial were reported at the World Vaccine Congress.

With an evolving understanding of T-cells in immunity and emerging SARS-Co-V2 strains, evaluating these vital protection cells can offer researchers insights into response and how to develop future therapies and vaccines.
