Why do some people get severe COVID-19? The nose may know
The body’s first encounter with SARS-CoV-2, the virus behind COVID-19, happens in the nose and throat, or nasopharynx. A new study in the journal Cell suggests that the first responses in this battleground help determine who will develop severe disease and who will get through with mild or no illness. Building on work published last ... Read More about Why do some people get severe COVID-19? The nose may know
Boston Children’s post-COVID clinic cares for those with lasting symptoms
One teenager complains of chronic muscle pain. Another child feels too exhausted to go to school or play sports. Still another can’t shake the feeling of “brain fog” — memory and cognition challenges. Despite their different symptoms, all three patients have one thing in common: They’ve all had COVID-19, and they’re all experiencing lingering symptoms ...

Children with severe MIS-C do better with IVIG and steroids as initial therapy
When children started getting sick with multisystem inflammatory syndrome (MIS-C) in the wake of COVID-19, clinicians largely turned to two treatments. Many used immunoglobulin (IVIG) because of MIS-C’s similarities with Kawasaki disease. And many used steroids such as methylprednisolone because of MIS-C’s inflammatory features. Key takeawayIn this large, rigorous national study, initial treatment of MIS-C ... Read More about Children with severe MIS-C do better with IVIG and steroids as initial therapy

Piecing together the preterm infant microbiome
The human microbiome — the collection of microbes living in the gut — is now recognized as an important contributor to health and disease. The environment, the host, and microbe-microbe interactions are all likely to shape the microbiome’s dynamics, but the unique roles of each are not well understood. Now, a Boston Children’s Hospital infectious ... Read More about Piecing together the preterm infant microbiome
Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
The fast-spreading U.K., South Africa, and Brazil variants are raising concerns and questions about whether current COVID-19 vaccines will protect against them. A structural biology study led by Bing Chen, PhD, at Boston Children’s Hospital now reveals how the D614G mutation — carried by all three variants — makes SARS-CoV-2 spread faster. Key takeaways: The main ... Read More about Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
If another pandemic hits, our online ‘footprints’ may help the experts
When the new coronavirus hit early last year, little was known about it. As people started coming to the emergency room, doctors scrambled to understand COVID-19 and its trajectory of symptoms. Testing was limited, and only over a period of months did the full fury of the new virus make itself known. Community after community ...

HPV vaccine: What families should know
Nearly 42 million Americans are currently infected with human papillomavirus (HPV), and most adults will be infected at least once in their lives. For most, HPV goes away on its own. If it doesn’t, it can lead to certain cancers. HPV can be transmitted sexually or by nonpenetrative skin-to-skin contact. Often, HPV does not have signs or symptoms, ...

Specialized T cells protect against the deadliest form of malaria
Each year, there are about 230 million cases of malaria globally. Children under the age of 5 are at highest risk of serious illness and death, accounting for about 265,000 deaths, or nearly 70 percent of all malaria deaths worldwide. Despite significant time and money poured into efforts to develop an effective malaria vaccine, the ... Read More about Specialized T cells protect against the deadliest form of malaria
What’s the difference between the COVID-19 vaccines?
After a long, difficult year, the world had reason to celebrate in late 2020 when the U.S. Food and Drug Administration (FDA) authorized two COVID-19 vaccines for emergency use. Many more COVID-19 vaccines are in various stages of development. Several of these are in the final stage of clinical trials and could be submitted for ...
