Moderna Inc. stopped its efforts to develop mRNA-1647 as a vaccine for preventing congenital cytomegalovirus infection, the most common infectious cause of birth defects in the U.S. The pivotal and placebo-controlled phase III CMVictory study of mRNA-1647 missed the primary efficacy endpoint, which was preventing the infection in seronegative females ages 16 to 40.

In vaccine development, one might think that targeting multiple epitopes increases the likelihood of improving outcomes. However, when several immunogens are administered together, the immune system does not always generate antibodies against all of them. Two parallel studies have overcome this challenge by using multiple simultaneous immunogens against HIV, effectively triggering various types of broadly neutralizing antibody (bnAb) precursors in two different preclinical animal models.

Researchers from Cincinnati Children’s Hospital Medical Center and collaborating institutions in the U.S. have developed a novel approach using allergen-encoding mRNA encapsulated in lipid nanoparticles (LNPs) for both therapy and prevention of allergic responses.

An uncommon route to the public markets – direct listing – paid off for Turn Therapeutics Inc., with shares (NASDAQ:TTRX) closing Oct. 9 at $9.20, up $2.20, or 31%, having risen as high as $26.50 in its second day of trading. The firm is advancing late-stage clinical programs in eczema and onychomycosis. Also in the works are global health initiatives in thermostable vaccine delivery designed to serve underserved areas.

Even though the U.S. CDC is operating on a skeleton crew due to the partial government shutdown, it is updating its immunization schedules to adopt the COVID-19 and chickenpox vaccine recommendations the Advisory Committee on Immunization Practices (ACIP) made at its September meeting.

While the discussions and votes at the past two meetings of the U.S. CDC Advisory Committee for Immunization Practices (ACIP) have generated a lot of controversy and resulted in some states and medical groups issuing their own vaccine schedules, the truth is that the newly reconstituted committee’s recommendations to date are still in line with, or more generous in some instances than, global norms.
