Vaccines

• Moderna and Merck announced on August 19, 2026, that their personalized mRNA vaccine, intismeran autogene, successfully passed a late-stage clinical trial. • The vaccine was used in combination with the immunotherapy drug Keytruda to effectively reduce the recurrence of melanoma, a form of skin cancer. • This milestone represents a significant breakthrough in oncology, demonstrating the potential for mRNA technology to transform both cancer treatment and prevention.

• Researchers are developing next-generation mRNA vaccines designed to direct the human immune system to attack and disassemble tumors tailored to an individual's specific cancer. • While current breakthroughs are promising for melanoma—which sees roughly 112,000 new U.S. cases annually—clinical trials are expanding to target hard-to-treat cancers of the lungs, bladder, kidney, and pancreas. • This shift represents a potential new era of personalized medicine that could revolutionize oncology by moving beyond traditional treatments to targeted immunotherapy.

• Merck and Moderna announced on Wednesday that their experimental cancer vaccine significantly reduced the return and spread of disease in a trial of over 1,000 melanoma patients. • The study focused on patients with high-risk localized tumors that had been surgically removed, aiming to prevent recurrence. • This breakthrough is significant as it could usher in a new wave of personalized cancer vaccines, with Moderna estimating thousands of patients could benefit shortly after approval.

• Donald Trump has issued orders directing the Department of Justice to target states and localities whose childhood immunization rules conflict with parental authority, religious freedom, and medical exemptions. • The orders include a call for the CDC to revise its vaccine recommendations to align with those of other developed nations and revive claims linking vaccines to autism, despite scientific refutation. • Critics argue these directives are dangerous as they encourage vaccine refusal, potentially placing millions of children at risk of preventable diseases.

The order cannot affect change, and is only ‘undermining trust in vaccines’ as CDC guidance remains the sameDonald Trump’s executive order on vaccines does not change the US recommendations for the shots – but experts say it does create confusion and doubt about vaccines, which will lead to more illness and possibly deaths among children and will make it harder for families and pediatricians to protect them.The executive order was an attempt to reinstate sweeping changes to the vaccine schedule made earlier this year by Robert F Kennedy Jr, secretary of the US Department of Health and Human Services and a longtime vaccine opponent – changes that were later halted by a federal judge.

• President Donald Trump issued an executive order calling for American children to be immunized against 11 diseases, a reduction from the 17 recommended by the CDC. • The legal authority and practical implementation of this order remain unclear, as it contradicts established public health guidelines. • In separate Oval Office remarks, the President made controversial claims regarding "jihadists" and "communism" being elected in various locations.

White House has halted changing vaccine schedule as it is unpopular, but anti-vaxx Trump set on ‘alleviating autism’Donald Trump is pushing longtime vaccine opponent and current health secretary Robert F. Kennedy Jr to be more aggressive on cutting vaccines in the US, according to reporting from the Wall Street Journal.Trump has a long record of anti-vaccine statements, but the White House recently put a hold on vaccine changes after polling indicated they were a losing issue in the midterm elections.

• A comprehensive review published in The Lancet reaffirms that approved mRNA vaccines are safe and highly effective across diverse populations, including children and immunocompromised patients. • Led by researchers from the University of British Columbia and Imperial College London, the study analyzed data from billions of doses, combining clinical trials with real-world surveillance. • The findings confirm that these vaccines significantly reduce documented SARS-CoV-2 infections, hospitalizations, and mortality within 14 to 42 days post-vaccination.

• Biotech companies including Soligenix, Moderna, Regeneron, and Aethlon Medical are accelerating the development of vaccines and therapeutics to combat a global outbreak of Bundibugyo ebolavirus in 2026. • Regeneron's maftivimab, a potent antibody found in the FDA-approved Inmazeb, has been recommended by the WHO's Therapeutics Advisory Group for use in clinical trials. • Aethlon Medical (Nasdaq:AEMD) is preparing to coordinate with global health authorities to deploy its Hemopurifier device as part of the medical response.

Reports say Texas recruits ill from outbreak, which comes weeks after defense secretary made flu vaccine optionalAn influenza outbreak has reportedly sickened more than 150 recruits in training at Lackland air force base in San Antonio, Texas.The outbreak comes just weeks after the defense secretary, Pete Hegseth, ended mandatory flu vaccination for the military, citing the need for bodily autonomy for servicemembers.

• During the Seventy-ninth World Health Assembly (WHA79) in May 2026, global health leaders reaffirmed their commitment to the Immunization Agenda 2030 (IA2030) to ensure universal vaccine access. • On the sidelines of the assembly, the Tuberculosis Vaccine Accelerator Council held its fourth meeting to coordinate efforts among funders, technical agencies, and civil society. • The council focused on accelerating the availability and access to novel TB vaccines specifically designed for adolescents and adults.

As Trump officials take aim at vaccine schedule, scientists encouraged by companies’ desire to continue coverageA group of insurers will continue covering routine vaccines through 2027 as the Trump administration once again takes aim at the shots and outbreaks of preventable illnesses such as measles and whooping cough lead to hospitalizations and deaths.Experts told the Guardian that the move has raised questions ahead of the November midterms, but certainly indicates that insurance companies believe vaccines are “safe and effective”.

• A rapidly widening epidemic of the Bundibugyo virus, a rare type of Ebola, is currently spreading across Africa. • A World Health Organization (W.H.O.) expert panel has recommended two monoclonal antibodies, maftimivab (by Regeneron) and MBP-134 (by Mapp Bio), for urgent clinical trials. • These treatments are significant because they utilize antibodies from survivors that can bind to glycoproteins across multiple strains, including Bundibugyo and Sudan viruses.

Executive order recognizes health department assessment as guide for federal government for childhood vaccinesDonald Trump signed an executive order acknowledging a recent scientific assessment by the Department of Health and Human Services on childhood vaccines as a guide for the federal government, the White House said on Friday.The order directs the US Centers for Disease Control and Prevention (CDC) and its Advisory Committee on Immunization Practices (ACIP) to review the HHS assessment and clinical data to update the vaccines schedule for children and adolescents, according to the text of the order.
