Cansino Biologics Inc. has obtained clinical trial approval from China’s National Medical Products Administration (NMPA) for the company’s 24-valent pneumococcal polysaccharide conjugate vaccine (CRM197/tetanus toxoid) (PCV24).
With the stroke of a pen and no input from the CDC’s Advisory Committee for Immunization Practices, acting CDC Director Jim O’Neill cut the number of vaccines the agency routinely recommends for children to 11 on Jan. 5, down from 17 in 2024.
Excessive production of pro-inflammatory cytokines or aging-related chronic inflammation disrupts immunity and diminishes the efficacy of vaccines, although the underlying mechanisms remain unknown. Moreover, these pro-inflammatory cytokines are linked to adverse vaccine reactions. These two issues can lead to vaccine hesitancy, resulting in lower vaccination rates.
If the 2025 U.S. life sciences regulatory scene were to be summed up in one word, it would have to be uncertainty. Two words might be more definitive – chaotic uncertainty.
Reporting sales of its hepatitis B vaccine Heplisav-B pretty much in line with consensus and a phase I/II shingles prospect moving along, Dynavax Technologies Corp. scored a takeover deal with Sanofi SA, which is paying $15.50 per share in cash for a total equity value of about $2.2 billion. The amount is a 39% premium to Dynavax’s closing share price yesterday, Dec. 23.
Driven by a deeply antiscientific political agenda, the current U.S. government is not just sabotaging some of the most groundbreaking technology that has been developed in the past decades. It is also destroying the country’s past successes, such as measles elimination and the reduction of hepatitis B infections in infants to near zero.
BioWorld’s 2022 end-of-year highlights included a toast to the future – of universal vaccines. Even before SARS-CoV-2 vaccines were developed in record time and saved countless lives during the COVID-19 pandemic, vaccines were a rare bright spot in the fight against infectious diseases. Bacteria are becoming multidrug resistant far faster than new classes of antibiotics are being developed, viral spillover events and vector ranges are increasing, and climate change is helping bacteria and fungi alike breach human thermal protections against infections.
Advances in antiretroviral therapy (ART) now allow people living with HIV to lead normal lives with undetectable and nontransmissible levels of the virus in their blood. Yet that reality is limited to those with access to treatment. More than 40 million people worldwide live with HIV, with over a million new infections and hundreds of thousands of deaths each year, underscoring that major challenges remain.
The U.S. CDC has adopted the recommendations of its Advisory Committee for Immunization Practices (ACIP) regarding the hepatitis B virus (HBV) vaccine scheduling for infants, determining that immunization should be an individual-based decision rather than the universal birth dosing practice that has been in place for the past 30 years.
The cardiomyositis that is a rare adverse effect of mRNA-based COVID vaccines is due to immune cell activity as a result of increased levels of the chemokines CXCL10 and interferon-γ (IFN-γ). Blocking CXCL10 and IFN-γ could prevent muscle cell damage in cell culture, and cardiomyositis in animal models. The findings, reported in the Dec. 10, 2025, issue of Science Translational Medicine, suggest a way of mitigating the risk of cardiomyositis.
