Model enables study of age-specific responses to COVID mRNA vaccines in a dish
mRNA vaccines clearly saved lives during the COVID-19 pandemic, but several studies suggest that older people had a somewhat reduced immune response to the vaccines when compared with younger adults. Why? Researchers at Boston Children’s Hospital, led by Byron Brook, PhD, David Dowling, PhD, and Ofer Levy, MD, PhD, found some answers — while providing ...

Will people accept a fentanyl vaccine? Interviews draw thoughtful responses
In 2022, more than 100,000 people died from opioid overdoses in the U.S., according to the National Center for Health Statistics. Roughly three quarters of these deaths involved fentanyl, a highly potent synthetic opioid. Fentanyl-related deaths have spiked over the past decade, many of them occurring in people with no known history of opioid use ... Read More about Will people accept a fentanyl vaccine?

Creating the next generation of mRNA vaccines
During the COVID-19 pandemic, mRNA vaccines came to the rescue, developed in record time and saving lives worldwide. Researchers in the Precision Vaccines Program at Boston Children’s Hospital have developed two novel technologies that could make these and future mRNA vaccines more potent and longer-lasting — at smaller doses and with fewer side effects. The ... Read More about Creating the next generation of mRNA vaccines
From ‘hit to vial’: Discovery and optimization of a promising vaccine adjuvant
Many vaccines are only partially effective, have waning efficacy, or do not work well in the very young or the very old. For more than a decade, Ofer Levy, MD, PhD, and David Dowling, PhD, in the Precision Vaccines Program at Boston Children’s Hospital, have tried improving vaccines by adding compounds known as adjuvants to ...

Boosting vaccines for the elderly with ‘hyperactivators’
As we age our immune systems start to flag, leaving us more susceptible to cancer and infections — and less responsive to vaccines and cancer immunotherapies. Going to the heart of the problem, Jonathan Kagan, PhD, a researcher in immunology at Boston Children’s Hospital, has identified a way to rejuvenate the elderly immune system. His ...

Nanobodies from alpacas could steer immune attacks on influenza
While conventional flu vaccines are designed to anticipate the influenza strains projected to dominate in the next flu season, they’re only partially effective. And while antiviral drugs are available to treat active flu cases, the body quickly clears them, requiring high, frequent doses. Coupling one existing flu drug with a special ingredient from alpacas, the ... Read More about Nanobodies from alpacas could steer immune attacks on influenza
Taming vaccine data: Joann Arce, PhD
Part of an ongoing series profiling researchers at Boston Children’s Hospital. Joann Arce, PhD, is a data tamer — corralling and wrangling vast quantities of data to extract insights on how our immune systems react to vaccines and infections. Her work is paving a path toward smarter, more potent vaccines. As lead of data management ... Read More about Taming vaccine data: Joann Arce, PhD
Research 2022: Tackling disease in new ways
Researchers across Boston Children’s spent 2022 imagining new solutions to old challenges in health and medicine, opening the door to brand-new treatments. Here are a few areas where research is poised to make a difference in children’s — and even adults’ — lives. Rethinking disease through genetics Genetic sequencing is becoming a fundamental tool for discovering ... Read More about Research 2022: Tackling disease in new ways
Using germs against themselves: How vaccines work
Germs are all around us. When a germ (in the form of virus or bacteria) enters your body, it tries to make you sick. Some germs cause minor colds, but others can cause serious disease. Fortunately, your immune system is your body’s internal defense system. It protects you by creating immune cells (T cells) and ... Read More about Using germs against themselves: How vaccines work
Powerful new antibody neutralizes all known coronavirus variants
As the COVID-19 pandemic wears on, newer variants of the SARS-CoV-2 coronavirus have been evolving ways to evade the antibodies we make in response to vaccines or prior infections. As a result, we’ve seen breakthrough cases, antibody treatments that once worked have also become less effective over time. Scientists have been searching for an antibody ...
