Tim Springer: Scientist, entrepreneur, and mentor
As an undergraduate in 1966, immunologist, biochemist, and biophysicist Timothy A. Springer, PhD, looked askance at science. The Vietnam War was going on, and he saw science as a means of making Agent Orange and napalm. Questioning his own Ivy League education, he left Yale to spend a year as a VISTA volunteer on a ...

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
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.

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
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
Nurses Week 2022: Leading an enterprise-wide response to COVID-19

Prior to the COVID-19 pandemic, the IPC department responded to a novel influenza pandemic and prepared extensively for patients with ... Read More
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
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
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 ...
