KFF poll finds vaccine myths reach many Americans but convince few

KFF’s 2026 tracking poll found that many U.S. adults have heard common vaccine myths, including false claims about MMR, COVID-19, mRNA vaccines, and measles vaccines. Fewer adults strongly believe these myths, but a large, uncertain “malleable middle” remains, especially among those without a trusted health care provider, frequent social media users, some AI health-information users, and parents who delayed or skipped childhood vaccines.

COVID-19 vaccine boosters may protect against future animal coronavirus outbreaks

COVID-19 vaccine boosters not only protect against SARS‑CoV‑2 – the virus behind the most recent pandemic – but may also help protect against some future coronaviruses that risk spreading from animals to humans, Cambridge researchers have shown.

Study links severe COVID to higher TB risk, and vaccination appears to blunt the link

A nationwide Chilean cohort study of more than 3.6 million adults found that severe COVID-19 requiring hospitalization was associated with more than an eightfold higher hazard of incident tuberculosis within one year. The association was strongest in the first six months and among unvaccinated individuals, although absolute TB incidence remained low.

High HPV vaccine uptake cuts cervical cancer deaths in women

A national HPV vaccination program in England is associated with a dramatic decline in cervical cancer deaths, reinforcing the vaccine's life-saving potential.

US study shows updated COVID vaccines cut hospitalization odds by 55%

The 2025-2026 COVID-19 vaccines were associated with 50% estimated effectiveness against COVID-19-associated emergency department and urgent care encounters among immunocompetent US adults. They were also linked to an estimated 55% effectiveness against COVID-19-associated hospitalization, providing added protection beyond existing immunity from prior infection or vaccination.

Study links COVID-19 to higher sleep apnea risk years after infection

Researchers analyzed more than 910,000 adults and found that SARS-CoV-2 infection was associated with a higher adjusted risk of new-onset obstructive sleep apnea up to 4.5 years later. The association appeared in both hospitalized and non-hospitalized COVID-19 patients, supporting targeted screening in higher-risk post-COVID groups while highlighting the need for objective sleep testing.

US adults are taking more supplements as multivitamins lose ground

A 25-year NHANES analysis of 63,442 US adults found that reported dietary supplement use rose from 51% to 60%, with the largest increases among adults aged 65 years and older. Use shifted away from multivitamin-multimineral products and toward vitamins, minerals, botanicals, and nonvitamin nonmineral supplements marketed for immune, anti-inflammatory, gut, skin, and joint health.

Tiny genetic change influences coronavirus spillover into humans

Most pandemics start when a pathogen spreads from animals to humans. It's a leading explanation for the COVID-19 pandemic: the SARS-CoV-2 virus, which causes COVID-19, is a cousin to coronaviruses that live in bats.

Leading AI models ace many vaccine questions but falter on clinical rules

A multilingual benchmark of 1,886 vaccine-related questions found that large language models answered most items accurately across English, Spanish, and Chinese. However, performance varied by vaccine type, language, and prompting method, with persistent errors in dosing, contraindications, age eligibility, and other clinically sensitive guidance.

Remote work explains part of the post-pandemic rise in mental distress

Researchers found that workers in remote jobs spent more time alone after the COVID-19 pandemic and experienced greater psychological distress than those in non-remote jobs. The effects were strongest among people living alone, suggesting that reduced everyday social contact may be an important cost of remote work.
