2026 FDA Approvals: Infectious Disease Vaccines

Projected disease burden from declining childhood vaccine coverage shows increases in vaccine-preventable diseases. Benjamin Lopman, PhD, provides insights on how VaxImpactMap works and the potential long-term disease consequences of decreased immunization rates.

The latest CDC numbers show a 6.2% increase of measles cases from week-to-week. Last week there was a 5.4% increase in cases showing a continuing steady increase dictated by ongoing outbreaks across the US.

In the phase 3 LIBERTY study, the investigational monoclonal antibody, VYD2311, had significantly fewer adverse events than an mRNA COVID-19 vaccine, and it did not blunt vaccine-induced neutralizing titers when the two were given together.

The latest CDC numbers show a 5.4% increase of measles cases from week-to-week. This year has already become the worst for the number of measles cases in the US since the disease was declared eliminated in 2000. With the start of respiratory virus season, case numbers are expected to continue to increase significantly.

A 39-year-old unvaccinated Franklin County woman has died after a recent measles diagnosis. Nationally, numbers continue to increase and the US has passed 4,000 cases.

The National Foundation for Infectious Diseases (NFID) recently held its respiratory season kick-off, which included the release of its annual respiratory disease survey. This year, the survey revealed the gap between vaccine support and uptake. Robert Hopkins Jr, MD, medical director of NFID delves deeper into the findings of the survey and the vaccine uptake challenges associated with certain immunizations.

The latest CDC numbers show a 5.0% increase of measles cases from week-to-week. The US total reached 4080 confirmed cases, 78% above all of 2025.

With US measles cases nearing 3,900 this year and Pennsylvania reporting its fifth measles-related death, here is a review of how the virus spreads, how it is prevented and managed, and what severe disease looks like.
