The FDA has approved Baloxavir Marboxil (Xofluza) for children 5 years and older to treat and prevent influenza.

The federal agency says it is indicated as a two-dose primary series for active immunization to prevent the virus in individuals 18 years of age and over.

An Israeli study found COVID-19 reinfection was "relatively rare," and previously infected persons who also received at least 1 dose of the Pfizer-BioNTech mRNA vaccine had an 82% reduced risk of reinfection.

The expectation of COVID-19 vaccination side effects may be leading some placebo recipients to report adverse events in vaccine trials.

Experiencing myocarditis after COVID-19 mRNA vaccination is rare, but more likely among persons under 24 years and male.

The US is on track to reach new records for 7-day average cases, though death rates remain lower.

The oral antiviral therapy proceeds the first indication for the drug class by just a day; the US will now have multiple pills to treat COVID-19.

Two different doses of the company's mRNA vaccine were found to increase antibodies by up to 83-fold.

New cohort data from VA medical centers provide more evidence of a correlate between antibody levels and vaccine effectiveness for mRNA vaccines.

A new report suggests FDA and CDC deliberations may result in booster doses of the mRNA vaccine becoming available by this weekend.

Interim, unpublished data show PAXLOVID is associated with 89% reductions in risk of COVID-19 hospitalization or death. Pfizer is now seeking FDA emergency authorization.

The Biden administration is also setting mandates for health care workers in facilities receiving federal aid.

The investigational oral antiviral therapy from Merck is still awaiting FDA authorization.

The ACIP considered the benefits of the newly emergency-authorized vaccine versus the risks of COVID-19 in children aged 5-11 years old.

Booster dose eligibility is broadening as the flu season approaches. An expert emphasizes the need to protect for both COVID-19 and the flu in the coming months.

Unpublished data from the company's ongoing pediatric trial show children aged 6 to <12 years old have an antibody response greater than that of young adults.

The FDA and CDC have authorized and recommended 3 different booster doses, to be used in "mix-and-match" strategy among eligible adults. What does this mean for immunity?

The actions taken by the FDA set differing availability of the 3 emergency-authorized vaccines.

The decision comes after supporting data from a "mix and match" trial last week, and may align with emergency authorizations for the Moderna and Janssen booster doses.

The VRBPAC meeting precedes deliberation from the FDA on amending the company's emergency authorization to include booster doses for adult patients.

As more agents expand the capability and variety of PrEP options, investigators consider what questions remain about the drug class.

Following the approval of cabotegravir-rilpivirine earlier this year, experts are looking forward to an expansion of the drug class for HIV.

The combination therapy's non-inferior efficacy to heavier TAF regimens may indicate a greater embrace of 2-drug regimens for people living with HIV.

Monica McArthur, MD, PhD, discusses why to-be-authorized COVID-19 vaccine doses for children may not be tiered for patient risk as they were for adults.

New late-breaking data illuminate the specific efficacy of the combination monoclonal antibodies.

A conversation in consideration of the high-risk psychosocial comorbidities the aging HIV population may face through COVID-19.

A new study from IDWeek showed most observed children previously infected with SARS-CoV-2 retained antibodies over 6 months.

An expert reviews cabotegravir, islatravir, lenacapavir, and what other promising agents that could redefine long-term HIV prevention.

Unpublished, interim phase 3 data show an approximate 50% reduction in hospitalizations and deaths versus placebo. Merck is expediting FDA application for the antiviral drug.

The study author of the late-breaking IDWeek findings discusses what the new data mean for using the antiviral to reduce COVID-19 burden.
