It was a busy day at Moderna Inc. as Merck & Co. Inc. exercised its option to jointly develop and commercialize a personalized cancer vaccine with Moderna in a deal the two companies inked in 2016. Moderna also notched another emergency use authorization (EUA) for its COVID-19 vaccine, this one targeting the omicron variant, for use by those under age 18.
Proof of concept has been achieved for a therapy for argininosuccinic aciduria consisting of human argininosuccinic lyase (ASL) mRNA encapsulated in lipid nanoparticles (ASL-LNPs).
In the hope of preventing thousands of hospitalizations and deaths over the next few months, the U.S. CDC’s Advisory Committee on Immunization Practice (ACIP) voted 13-1 Sept. 1 to recommend the use of Moderna Inc.’s and Pfizer Inc.-Biontech SE’s updated vaccines that contain components of both the original SARS-CoV-2 virus and the omicron BA.4/5 subvariants as boosters.
Right on cue, the U.S. FDA authorized bivalent COVID-19 vaccines from Moderna Inc. and Pfizer Inc.-Biontech SE to be given as boosters at least two months following a primary vaccine series or a previous booster. “These updated boosters present us with an opportunity to get ahead of the next wave of COVID-19,” FDA Commissioner Robert Califf said, following the Aug. 31 announcement.
Three of the biggest COVID-19 vaccine developers are heading into a legal battle. Moderna Inc. said it has filed lawsuits alleging the Pfizer Inc.-Biontech SE Comirnaty vaccine infringes patents Moderna filed between 2010 and 2016 that cover its mRNA technology. Pfizer and Biontech “unlawfully” copied the technology without permission, according to Moderna.
Moderna Inc.’s and Pfizer Inc.-Biontech SE’s COVID-19 bivalent boosters could be coming to the U.S. in the first week or so of September – even though the U.S. FDA just received the completed emergency use authorization (EUA) requests for the vaccines this week. The CDC is already taking pre-orders from providers, states and other jurisdictions for the yet-to-be authorized booster doses as part of its fall-winter booster campaign strategy. It also scheduled a Sept. 1-2 meeting of its Advisory Committee for Immunization Practices, signaling that it expects the FDA to grant the EUAs by the end of August.
While other COVID-19 vaccine makers are developing bivalent boosters comprising the original SARS-CoV-2 strain and an omicron variant, Russia’s Gamaleya National Research Center of Epidemiology and Microbiology is trekking a different course. Leaving behind the ancestral strain, Gamaleya’s next generation of the Sputnik V vaccine has been specifically adapted against delta and omicron variants of the coronavirus.
Moderna Inc. has received conditional authorization from the U.K.’s Medicines and Healthcare Products Regulatory Agency for its bivalent COVID-19 booster vaccine mRNA-1273.214 (Spikevax bivalent original/omicron). The conditional approval, which covers adults aged 18 years and older, marks a new phase in the ongoing global effort to curb the COVID-19 pandemic, as the new vaccine represents the first commercial product to incorporate omicron-specific epitopes. It contains 25 micrograms each of the spike proteins of the omicron BA.1 variant and the original Wuhan strain of SARS-CoV-2.
Now that the U.S. Department of Health and Human Services (HHS) has declared monkeypox a public health emergency, nearly two weeks after a similar declaration from the World Health Organization, the way is cleared for a coordinated response and emergency use authorizations to address supply challenges that could limit the availability of currently approved vaccines. It also has several companies ready to leap into the fray if their preclinical studies show a path to approval. HHS said it just shipped more than 602,000 doses of the Jynneos vaccine to states and jurisdictions, an increase of 266,000 in the past week.
European regulators have added several safety messages to approved COVID-19 vaccines, including a warning that Novavax Inc.’s Nuvaxovid could produce severe allergic reactions.
