The new case involves a metro Atlanta resident who is related to a person who acquired measles abroad. Neither had been vaccinated.

Here's a Q&A with Dr. Maureen Miller, a researcher for the study, which found that in one year, vaccine uptake rose from 44% to 76% in target communities.

Countries that produced their own vaccines in the Covid-19 pandemic had first dibs on the shots. While the U.S., home to Moderna and Pfizer, rolled out second doses of mRNA vaccines in 2021, hundreds of thousands of people in countries that didn’t manufacture vaccines died waiting.

Pregnant women who contracted Covid-19 were more likely to become severely ill and to be hospitalized than non-pregnant women of the same age and demographics.

The FDA will encourage new clinical trials on the widely used vaccines before approving them for children and healthy adults. The requirements could cost drugmakers tens of millions of dollars and are likely to leave boosters largely out of reach for hundreds of millions of Americans this fall.

Schools, social media, bullying and violence are among the top concerns in the survey.

While some experts were pleased that Robert F. Kennedy Jr. supported any vaccine project, they said the grant contravened sound scientific policy, appeared arbitrary, and raised questions about conflicts of interest.

Beliefs about the safety of the measles vaccine and the threat of the disease are sharply polarized. About two-thirds of Republican-leaning parents are unaware of an uptick in measles cases this year, while about two-thirds of Democratic ones knew about it, according to a new survey.

The abrupt cancellation of funds sent state Department of Public Health leaders scrambling to understand the impact and inform contractors, including many community organizations, to stop work immediately.

In a Q&A, one of the project’s principal investigators describes the 'devastating' termination of grant funding for research that was nearing completion.

The terminations have spared no part of the country, politically or geographically. Of the organizations that had grants cut in the first month, about 40% are in states President Donald Trump won in November.

The state's vaccination rates have been on the decline for years, with overall measles protection below the 95% rate needed for herd immunity.

Launched to combat vaccine misinformation, Out of Hand Theater's EqVax program used a blend of theater, art, storytelling, and community dialogue to build trust in vaccines among underserved communities.

Immunization efforts across the country were upended after the federal Centers for Disease Control and Prevention abruptly canceled $11.4 billion in Covid-related funds for state and local health departments in late March.

It is the only state that no longer collects immunization reports from local schools, creating a data gap for the Centers for Disease Control and Prevention. State lawmakers are considering a bill to undo the policy.

National Institutes of Health officials have urged scientists to remove all references to mRNA vaccine technology from their grant applications, two researchers said, in a move that signaled the agency might abandon a promising field of medical research.

State and federal lawmakers have proposed measures to limit mRNA vaccines and even punish doctors who give them.

Dr. Roy Benaroch explains how measles can spread, what short-term and long-term effects measles can have on children, and what steps parents can take to keep their kids and communities healthy.
