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.

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.

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

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 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.

An English modeling study suggests level of protection decreases only very slightly over time and reminds parents to have their children up to date on all vaccinations.

The findings are from a National Foundation for Infectious Diseases (NFID) survey showing many Americans are not thinking about flu, COVID-19, RSV, or pneumococcal disease, and many respondents do not plan to get vaccinated this fall.
