“People don’t recognize that at least 1 in 5 of the deaths from opioids may result from endocarditis,” said National Institute of Drug Abuse (NIDA) director Dr. Nora Volkow, adding that endocarditis is “100% preventable.”

Convalescent plasma safely raised antibody levels in children at high risk of severe or fatal COVID-19, successfully neutralizing the virus but unlikely to provide lasting protection.

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

A novel digital pill was 98% effective in tracking daily HIV PrEP adherence.

HPV vaccination decreases cervical cancer incidence and mortality, but it is most effective in young women and girls.

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

Merck announced an enrollment pause in 2 of their stage 3 clinical trials for once-monthly oral islatravir for HIV PrEP. Enrolled participants will continue receiving study medicine.

Unpublished data from the company's ongoing pediatric trial show children aged 6 to 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 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.

People who inject drugs in rural areas had a less accurate understanding of HIV PrEP, largely due to stigma surrounding sexual orientation and drug use.

The findings have supported the launch of a phase 3 trial called EVERGREEN, which is now underway.

In the primary efficacy analysis, the risk of developing symptomatic COVID 19 was reduced by 77% with AZD7442.

A presentation of available third-dose data suggest the adverse event rate is consistent with that observed with second doses.

Preprint data from a real-world evidence assessment, as well as preliminary reports from a 2-dose trial, support the company's pursuit for FDA authorization of a second COVID-19 vaccine dose.

Though efficacy waned over months, protection from symptomatic and severe COVID-19 remained significant, with no new adverse event risks observed.

A neighborhood-level assessment of major cities show areas impacted the most by historic COVID-19 deaths are significantly less vaccinated.

New Imbokodo findings show a 4-dose regimen was only about 25% effective in preventing HIV in at-risk women, hindering progress for the vaccine.
