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
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
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
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
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 ... Read More
A new vaccine formulation could finally protect babies against RSV
Though often mild, respiratory syncytial virus (RSV) infection can cause babies to be hospitalized with bronchiolitis or pneumonia. Globally, it is the leading cause of death in children under 5. Several vaccines against RSV are being tested in adults. But there has been no progress on an RSV vaccine for children since 1966 — the ... Read More
COVID-19 vaccines are now available for kids under 5. Here’s what parents should know.
Children under age 5 can now be vaccinated against COVID-19. The Centers for Disease Control and Prevention (CDC) recently approved the use of vaccines produced by Pfizer-BioNTech and Moderna in children ages 6 months and older. We spoke with Dr. Kristin Moffitt, a pediatric infectious disease specialist at Boston Children’s, to get answers to your questions. ... Read More
Pregnant mothers who get COVID-19 vaccines are also protecting their babies
Recent studies have shown that COVID-19 vaccination is safe for expectant mothers and can protect them against infection, severe illness, and death from COVID-19. We also know that mothers vaccinated during pregnancy pass coronavirus antibodies to their babies. The latest research — drawing on 30 children’s hospitals in 22 states — now confirms that vaccinating ... Read More
Previous COVID-19 or MIS-C does not protect kids from Omicron
You would think that having had COVID-19 once, you’d have antibodies that would protect you against repeat infections. But studies of adults have shown that Omicron doesn’t go by that logic. A new study, led by Dr. Adrienne Randolph of Boston Children’s Hospital and Dr. Surender Khurana of the Food and Drug Administration, confirms that ... Read More
Old vaccine, new tricks? Unlocking the BCG vaccine’s potential
Could a century-old vaccine offer clues for designing the vaccines of tomorrow? Ofer Levy, MD, PhD, director of the Precision Vaccines Program at Boston Children’s Hospital, wants to find out. One of the world’s oldest and most widely used vaccines, the Bacille Calmette-Guérin (BCG) tuberculosis vaccine may at first seem like an unlikely source of ... Read More
