Researchers around the globe are working with unprecedented speed to find the vaccines we need to find our way through the pandemic. What’s the bar for safety and effectiveness?
COMIC: As it spreads throughout the world, the virus that causes Covid-19 has been changing. Scientists are tracking those changes, hoping to stay one step ahead of worrisome strains.
Public health messages should be loud and clear, so that everyone listens and stays safe. But that’s easier said than done — especially with a case as complex as Covid-19.
The body’s defenses lose flexibility and diversity over time, and protective responses to vaccines weaken as well. Scientists are working on ways to boost seniors’ protections against influenza, the novel coronavirus and other pathogens.
Covid-19 has exposed the weak spots of the US public health system — and that presents an opportunity, says an epidemiologist, for the nation to recognize the problems and act to fix them
TIMELINE: From colonial efforts to control smallpox outbreaks to antimalarial campaigns targeting mosquitoes, the American effort grew for centuries. But cutbacks have weakened it in the past decades.
OPINION: Many health facilities were already in fiscal straits before Covid-19 — except in Maryland. The state’s innovative and sound approach could be the answer to rescuing systems nationwide.
OPINION: Many Americans say they won’t take a vaccine. I am not one of <br xmlns="http://pub2web.metastore.ingenta.com/ns/"/>them — and I have the shots to prove it.
As Covid-19 descended across the world, people sought refuge in gardens, parks and the woods. But it’s hard to measure how being in nature affects our well-being — and how we can best reap its rewards.
OPINION: A neuroscientist says that he’s particularly worried about kids, who may have spent much of last year learning online. Some easy hacks can help.
Antibiotics abound, but virus-fighting drugs are harder to come by, and Covid-19 amply shows how much we need them. Fortunately, scientists are getting better at making and finding them.
Some children have been hospitalized and some have died, but at a tiny fraction of the adult rate. As children head back to school, scientists are hoping that research will provide answers.
