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

Beyond COVID-19: Why kids need other vaccines, too
As you consider immunizing your child, it’s natural to have questions about the safety and effectiveness of vaccines. But the detection of polio in New York illustrates how diseases that were once thought to have been eradicated can reemerge when vaccination efforts lag. While COVID-19 vaccines have understandably drawn attention during recent years, it’s important to remember ... Read More about Beyond COVID-19: Why kids need other vaccines, too

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 ...

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 ...

How COVID-19 triggers massive inflammation
Why do some people with COVID-19 develop severe inflammation, leading to respiratory distress and damage to multiple organs? A new study in the journal Nature provides an explanation: the SARS-CoV-2 virus infects and kills critical immune cells in the blood and lungs, which set off powerful alarm bells as they die. Judy Lieberman, MD, PhD, ... Read More about How COVID-19 triggers massive inflammation
COVID vaccination in 5- to 11-year-olds: What does the science say?
The Pfizer–BioNTech COVID-19 vaccine was approved for children ages 5 to 11 in October, but many parents have been hesitant to get them vaccinated. A national study in The New England Journal of Medicine provides reassuring data, showing that the vaccine strongly protected this age group against severe COVID-19. Dr. Adrienne Randolph at Boston Children’s ... Read More about COVID vaccination in 5- to 11-year-olds: What does the science say?

A new symptom of COVID-19 in young children: Croup
During the Omicron surge, pediatricians and emergency departments (EDs) began noticing something new: a surge in croup among infants and young children. Marked by a distinctive “barking” cough and sometimes noisy, high-pitched intakes of breath, croup can happen when colds and other viral infections cause the voice box, windpipe, and bronchial tubes to become inflamed ...

Real-time genomic surveillance of bacteria could improve antibiotic therapy
Antibiotic-resistant bacterial infections are increasingly hard to treat, causing more than a million deaths annually around the world. Hospitalized patients with pneumonia, bloodstream infections, urinary tract infections, or abdominal infections are especially at risk. Like a game of Whac-A-Mole, bacteria can develop antibiotic resistance mutations within days of starting an antibiotic, only to be replaced ...
