Researching Antimicrobial Resistance to Save Lives Around the World

Image for Researching Antimicrobial Resistance to Save Lives Around the World

There are approximately 500 million households that practice small scale food animal production around the world, yet it is often overlooked in terms of the environmental health risks. Research from PHI's Jay Graham and partners found evidence suggesting that small-scale food animal producers often employ the use of antimicrobials to improve the survival and growth of their animals, and that this practice leads to the development of antimicrobial resistance (AMR) that can spread to humans. The nature of human-animal interactions in small-scale food animal production, generally practiced near the home, likely adds to spillover events of AMR into the community on a scale that is currently unrecognized and deserves greater attention. 

Researchers were also able to identify certain risks associated with food-animal production that will be essential for the safe development programs that promote livestock and poultry for improved livelihoods and nutrition.

Breakthrough Infection Study of Over 600,000 Veterans Shows Declining COVID-19 Vaccine Protection

A new pre-print study of over 600,000 veterans by researchers from PHI and the Veterans Affairs Medical Center finds that overall COVID-19 vaccine protection declined significantly between February and August 2021. Declines were greatest for the Johnson & Johnson vaccine (from 88% in March to 3% in August), followed by PfizerBioNTech (91% to 50%) and Moderna (92% to 64%).
