Vaccines

The most recent CDC report accounts for 33 million flu illnesses, 430,000 hospitalizations, and 19,000 deaths this flu season, with Influenza A(H1N1) and A(H3N2) as the primary strains.

The World Health Organization (WHO) reports on the vaccine uptake in that region, and the Global Polio Eradication Initiative reports that some countries recording new cases.

A new study published in JAMA Network Open points out that immunization also occurred in individuals who did not receive routine prenatal or infant vaccines.

Confirmed measles cases in Texas have risen from 24 to 58 in just six days, with 13 hospitalizations reported.

The company's trivalent vaccine (mRNA-1403) was being studied in a phase 3 trial.

In a statement, the official, Ralph Abraham, MD, along with the state’s deputy surgeon general, wrote that because of “COVID missteps” they will no longer encourage vaccination to people.

In the Phase 3 trial, GSK's vaccine met all 11 primary endpoints, providing expanded options for preventing invasive meningococcal disease in individuals aged 10-25 years.

The approval is based on positive phase 3 clinical trial results, offering an effective option for travelers and others at risk of chikungunya, the mosquito-borne illness.

Su H Wang, MD, FACP, MPH discusses combating vaccine misinformation, preventing outbreaks, and highlighting global health interconnectedness

Heather Platt, MD, discusses Merck’s latest achievement with Capvaxive and its potential to significantly reduce invasive pneumococcal disease and pneumonia in high-risk adult populations across Europe.

The association’s Executive Director Georges Benjamin, MD, offers some commentary as to why they have concerns around him as Health and Human Services Secretary.

Robert Walker, MD discussed the company's application for full licensure and the importance of vaccination.

The latest Phase 2/3 trial results show NVX-CoV2601 outperforms its predecessor, offering protection against emerging COVID-19 strains.

Vaccines and treatments are up for approval in early to mid-2025, including a chikungunya vaccine, a meningococcal vaccine, a monoclonal antibody for RSV, and more.

In a small trial, the Hecolin hepatitis E vaccine demonstrated further utility outside of previous study parameters.

The federal government is working on measures to mitigate the potential impact including looking at vaccines, therapies, and other strategies. Robert Hopkins, Jr, MD, medical director, National Foundation for Infectious Diseases (NFID), provides some insights on our preparation now and lessons learned from the pandemic.

The Phase 1 clinical trial for ARCT-2304, a self-amplifying mRNA vaccine, seeks to address pandemic influenza risk as H5N1 cases increase.

As politics increasingly intersects with science, infectious disease clinicians are called to take on advocacy roles. By engaging with their communities, clinicians can dispel misconceptions, highlight the importance of federal health institutions, and emphasize their role in safeguarding public health and advancing medical progress.

The continuation of misinformation and disinformation being disseminated in the public is causing more public health communication issues as mistruths associate the vaccines with cancer.

The federal agency approved safety labeling changes to the prescribing information for Abrysvo (Pfizer) and Arexvy (GSK) RSV vaccines for seniors after data from clinical trials, reports to the Vaccine Adverse Event Reporting System (VAERS), and a postmarketing study.

The updated recommendations simplify vaccine eligibility while addressing both cost-effectiveness and racial health disparities.

Investigators evaluated strategies to simplify the vaccination process to yield higher rates of adult immunization, similar to that of the COVID-19 pandemic.

Reactogenicity of mRNA COVID-19 with inactivated influenza vaccine was similar whether given at same time or separated by 1-2 weeks.

New approach targets multiple strains, promising broad protection against human, avian, and swine influenza viruses.

The investigational vaccine amezosvatein demonstrated low reactogenicity, supporting its potential as an alternative for shingles prevention in adults 50 and older.

This new indication for the bivalent respiratory syncytial virus prefusion F vaccine (Abrysvo) makes it the broadest currently available.

Important vaccine updates, including a second COVID-19 vaccine dose for adults 65 and older and immunocompromised individuals, a pneumococcal vaccine for adults aged 50 and older, and more.

A serious adverse event of motor neuropathy reported in September 2024 has resulted in a hold on the investigational new drug application.

The vaccine proved a cumulative efficacy of 62.9% against respiratory syncytial virus-related lower respiratory tract disease in older adults over three seasons.

A single dose of the mRNA-1273.222 vaccine demonstrated strong immune responses against various omicron subvariants and showed a favorable safety profile compared to existing vaccines.
