Jane Greenhalgh

Jane Greenhalgh is a senior producer and editor on NPR's Science Desk.

She produces the weekly Health segment on NPR's Morning Edition and writes and edits for NPR's health blog, "Shots." Greenhalgh also produces stories on science, health, and global health across NPR's many platforms.

Greenhalgh was part of the team of broadcast, digital, and multimedia journalists who produced the 2015 award-winning series "#15Girls," which examined the struggles teenage girls face throughout the developing world. Greenhalgh's story "Banished to the Shed" was one of NPR's most listened to and viewed stories of 2015.

She has twice won The American Association for the Advancement of Science award: In 2020 for her work on Victoria's Story: Gene editing helps people with sickle cell, and for NPR's 2014 series "The human microbiome: guts and glory." Greenhalgh also won The National Academies of Science Communication award in 2014, and she was part of the digital team which won for the 2009 series Climate Connections. She traveled extensively for this year-long, multi-platform project, examining how climate change is affecting people across the globe. From Timbuktu, where the desert nomads are giving up their way of life, to Peru, where potato farmers are moving their crops higher up the mountain, and to Bangladesh, where scientists are experimenting with drought and flood resistant rice, the stories Greenhalgh produced chronicled the impact of climate change.

Greenhalgh has traveled extensively covering health issues in developing countries, including cholera in Haiti, polio in Indonesia, tuberculosis in Kenya, AIDS in India, malaria in the Gambia, malnutrition in Bolivia, and menstrual health in Nepal.

A third dose of the Moderna vaccine — given six months after the initial two doses — significantly boosts immunity, according to data the company submitted to the Food and Drug Administration on Wednesday.

People with compromised immune systems who already got two doses of the Pfizer or Moderna vaccines can now get a third shot to boost their protection from COVID-19.

This week's decision by federal health agencies is welcome news to many patients and their doctors who have been calling for this for months.

The Food and Drug Administration is authorizing an additional dose of a COVID-19 vaccine for certain people with weakened immune systems caused either by disease, medical treatments or organ transplants.

The move comes after studies have shown these people may not have sufficient immunity to head off the more serious complications of COVID-19 after the standard vaccine regimen.

Life expectancy in the United States declined by a year and a half in 2020, according to the Centers for Disease Control and Prevention, which says the coronavirus is largely to blame.

COVID-19 contributed to 74% of the decline in life expectancy from 78.8 years in 2019 to 77.3 years in 2020, according to the CDC's National Center for Health Statistics.

The highly contagious delta variant now accounts for more than 51% of COVID-19 cases in the U.S., according to new estimates released by the Centers for Disease Control and Prevention. The variant, also known as B.1.617.2, was first detected in India and is spreading quickly across the globe.

And in parts of the U.S., the delta strain accounts for more than 80% of new infections, including some Midwestern states such as Missouri, Kansas and Iowa.
