A year and a half gone, two HIV vaccine studies shut down. That’s the case with the Janssen Pharmaceutical Cos. of Johnson and Johnson as the phase III Mosaico study of its HIV vaccine regimen was not effective in preventing infection compared to placebo. Based on a data and safety monitoring board’s report saying the study was not expected to hit its primary endpoint, Janssen discontinued the clinical trial more than a year ahead of its estimated March 2024 completion date.

Researchers from Therapyx Inc. and Intravacc BV assessed the potential of intranasal administration of a novel gonococcal vaccine candidate consisting of outer membrane vesicles (OMVs) and microsphere (ms)-encapsulated interleukin-12 (IL-12 ms). It was previously demonstrated that female mice can be immunized intravaginally with gonococcal OMVs plus IL-12 ms to induce anti-gonococcal antibodies and resistance to genital tract challenge with live Neisseria gonorrhoeae.

Sen. Bernie Sanders (I-Vt.), the incoming chair of the U.S. Senate Health, Education, Labor and Pensions (HELP) Committee, penned a blistering letter that takes Moderna Inc. CEO Stéphane Bancel to task over the company’s plans to more than quadruple the U.S. list price of its COVID-19 vaccine once the government’s supply is depleted.

A Harvard Medical School research team developed a bifunctional therapeutic vaccine strategy by transforming living tumor cells into a potent agent with direct tumor killing and immunostimulatory abilities.

Researchers at the University of Cape Town have compared the T-cell responses of individuals who were infected with Mycobacterium tuberculosis but were able to control the infection to those who developed active disease. The researchers wrote that the shared antigens in controllers “can be considered as high-priority targets for future vaccine development.” Their results were published online in Nature Medicine on Jan. 5, 2023. In their experiments, the team first sequenced the CDR3β region of the T-cell repertoire in a total of 166 individuals with M. tuberculosis infection who progressed to either TB or controlled infection.

After comparing the response to the two types of vaccines for the respiratory syncytial virus (RSV) based on its fusion protein (F), prefusion (pre-F) versus postfusion (post-F) vaccines, scientists at the National Institutes of Health (NIH) and Astrazeneca plc have demonstrated that targeting the pre-F protein led to better protection. No more bets on RSV immunization based on the post-F protein of the virus. Laboratories can now bet all on red for the pre-F technology.

Ice, juice, the exact measure of liquor, a few drops of Angostura... What goes into a good New Year’s Eve cocktail? According to researchers working on vaccines for the most elusive viruses, it will be time soon to toast next-generation vaccines. If 2020 was the year of the COVID-19 pandemic, and in 2021 the year of mRNA vaccinations, 2022 brought polyvalent designs of antigens, evaluated highly neutralizing antibodies, and fine-tuned mRNA technology against SARS-CoV-2, HIV and the flu.
