Icosavax announced Wednesday the close of $100 million in Series B financing.

The funds will support the development of the biotech’s bivalent RSV and human metapneumovirus vaccine through initial clinical studies, continued evaluation of its virus-like particle (VLP) Covid-19 vaccine candidate, and expansion of its pipeline of other VLP vaccine candidates targeting respiratory diseases, the press release said.

Roche announced Monday that it will buy California-based GenMark Diagnostics for $1.8 billion in cash.

The Swiss biotech will expand its portfolio with GenMark’s molecular diagnostic tests, including the ePlex Respiratory Pathogen Panel, which simultaneously screens for several bacteria and 21 viruses (including influenza A and B, RSV and SARS-CoV-2). The announcement came days after the U.S. FDA issued a warning about false positives from Roche’s own multivirus diagnostic.

Adjuvant Capital announced last week a $300 million Global Health Technology Fund focused on accelerating the development of medical innovations for “historically overlooked public health challenges.”

GSK announced positive Phase 1/2 data Wednesday for two RSV vaccines, calling the candidates “well-tolerated and highly immunogenic.” Presenting the results at the IDWeek infectious disease conference, the company said both recombinant subunit pre-fusion shots—one for maternal immunization and another for older adults—will proceed to Phase 3 “in the coming months.”

Phase 1/2 trials for a third GSK RSV vaccine candidate (for infants) remain ongoing.


Moderna has “regained all rights” to the respiratory syncytial virus (RSV) vaccine that it has been co-developing with long-time collaborator Merck, the Massachusetts-based company announced last week. The press release said Merck will complete ongoing Phase 1 trials of lipid nanoparticle-based mRNA-1172 before formally handing over the program and that Merck will focus on its RSV antibody program, currently in Phase 2.

With programs in various stages of clinical development, GSK, J…

Vaccine published first-in-human Phase 1 results for Intravacc’s RSV vaccine candidate in its September 3 issue, finding the intranasal live-attenuated product safe and well-tolerated in healthy adults ages 18 to 50.

Noting in its press release that high background immunity among adults makes efficacy difficult to evaluate, the Dutch company said that it’s seeking a partner for pediatric clinical development.


With competitors challenging Prevnar 13—the pneumococcal conjugate vaccine (PCV) responsible for 90% of its vaccine sales—Pfizer this week announced the start of Phase 3 trials for three investigational shots.

Two separate studies will compare 13-valent Prevnar with the company’s 20-valent candidate, 20vPnC, in approximately 3,500 infants.

Meanwhile, a study evaluating the safety and efficacy in infants of Pfizer’s respiratory syncytial virus (RSV) vaccine candidate, RSVpreF,…
