A 194-country analysis reveals gaps in how late childhood vaccinations are tracked

A global analysis of WHO/UNICEF data from 194 countries found wide variation in countries’ ability to record delayed childhood vaccinations, with 64% of reporting countries saying they could capture late doses in 2022. Following birth cohorts over time and adding delayed MCV1 doses raised median coverage estimates by 3.6 to 5.1 percentage points across available cohort years, though incomplete and inconsistent reporting limited confidence in some estimates.

The US switch in shingles vaccines revealed an unexpected heart health pattern

In a natural experiment involving 72,920 propensity-matched US adults aged 60 years and older, recombinant shingles vaccination was associated with a 9% lower cardiovascular disease burden over seven years compared with the live attenuated vaccine. Lower burdens of ischemic heart disease and heart failure were seen in both sexes, while ischemic stroke was significantly lower only among men, supporting further clinical trials and mechanistic studies

Sewage monitoring may provide earlier warning of pertussis outbreaks

Pertussis, or whooping cough, continues to cause periodic outbreaks worldwide and can be especially dangerous for infants who have not completed vaccination.

Why pregnancy vaccination looks very different in Germany than it did 19 years ago

A 19-year German claims analysis of more than 2.8 million pregnancies found that recorded maternal vaccination increased substantially after national recommendations for influenza and pertussis immunization were introduced. Influenza vaccination reached 19.4% and pertussis vaccination about 37% in 2020-2022, while COVID-19 vaccination was not captured in the databas

Pregnant women use Reddit to seek Tdap vaccine reassurance

An analysis of Reddit posts about the maternal Tdap vaccine made by pregnant women reveals expectant mothers turning to Reddit to seek advice and reassurance-with fewer outright instances of vaccine hesitation/refusal than has generally been observed for other types of vaccines, according to a study published on August 12, 2026 in the open access journal PLOS Global Public Health by Soojung Jo from Purdue University, United States, and colleagues.

New website tracks vaccine preventable diseases across the United States

A new website will track the spread of vaccine-preventable diseases across the United States to offer the public, the media, healthcare providers, public health officials, and policymakers reliable and visual information about current disease trends.

Research reveals how a hidden immune cell army defends human lung tissue

New research led by scientists at La Jolla Institute for Immunology (LJI) and University of Liverpool (UOL) provides the first comprehensive look at how a hidden immune cell army defends the vast, vulnerable tissue of the human lungs.

Survey finds widespread uncertainty over pregnancy vaccine recommendations

Most Americans are unaware or unsure of which vaccines the Centers for Disease Control and Prevention (CDC) recommends during pregnancy, according to a nationally representative survey of U.S. adults by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

Global child immunization rates stall despite minor pandemic recovery

In 2025, 90% of infants globally – or nearly 116 million – received at least one dose of a diphtheria, tetanus and pertussis (DTP) vaccine, and 85% – or 110 million – completed the full three-dose series, according to the annual WHO-UNICEF Estimates of National Immunization Coverage (WUENIC) released today.

Aged immune cells may drive memory decline by releasing a brain-aging protein

A preclinical mouse study in Immunity suggests that aged circulating CD8+ T cells can disrupt hippocampal function and impair learning and memory. The findings point to granzyme K, a secreted factor linked to age-associated CD8+ T cells, as a potential target for restoring aspects of cognition in aging.

Extensive data analysis confirms the safety of aluminum adjuvanted vaccines

Current evidence does not support direct (causal) associations between aluminium adjuvanted vaccines and serious or long-term health outcomes, including autism, diabetes, and asthma, finds a review of the latest data published by The BMJ today.

Why Japan saw a major pertussis surge in 2025 while other countries peaked earlier

This study found that pertussis cases fell across Japan, Australia, New Zealand, China, and the USA during COVID-19 restrictions, then resurged afterward, with most countries peaking in 2024 but Japan showing a delayed major outbreak in 2025. In Japan, the surge was concentrated in school-aged children and adolescents, highlighting possible gaps in booster protection and the need to reassess immunization strategies.

US measles and pertussis outbreaks expose policy failures, not just vaccine hesitancy

A recent commentary argues that US measles and pertussis outbreaks are not simply the result of vaccine hesitancy but reflect weakened immunization policies, permissive exemptions, and underfunded public health systems. The authors contend that policy environments determine whether pockets of low coverage escalate into large-scale, preventable outbreaks.

Study suggests shingles vaccine may help lower Alzheimer’s and dementia risk

A large observational electronic health record study found that older adults receiving the recombinant zoster vaccine showed substantially lower rates of diagnosed dementia compared with matched unvaccinated individuals. The association persisted after multiple sensitivity analyses, although causality remains unproven and longer follow-up is required given the long latency of dementia.

Vaccines are helping older people more than we knew

Let's be clear: The primary reason to be vaccinated against shingles is that two shots provide at least 90% protection against a painful, blistering disease that a third of Americans will suffer in their lifetimes, one that can cause lingering nerve pain and other nasty long-term consequences.

Long-term study reveals shifting patterns in COVID-19 vaccine hesitancy

Most COVID-19 vaccine hesitancy is rooted in concerns that can be addressed and effectively reduced over time, according to a new study following more than 1.1 million people in England between January 2021 and March 2022 during the COVID-19 pandemic, published in The Lancet.
