Chinese Covid-19 vaccines offer relatively low levels of protection compared with some of their foreign rivals. Here is why China is joining other countries in considering mixing and matching vaccines as a key to overcoming multiple vaccination challenges at once. Illustration: Ksenia Shaikhutdinova

The risk of dying from COVID is much higher than getting a blood clot from a vaccine. But even more concerning is a new report from Oxford University that shows catching the coronavirus puts you at even more risk of a deadly blood clot. Each delay puts more lives at risk, as the coronavirus spreads. It’s a balancing act between speed and caution in the fight against COVID-19.
From a sore arm to anaphylaxis, a wide range of adverse events have been reported after people have received a COVID-19 vaccine. And yet it is unclear how many of these events are actually caused by the vaccine. In the vast majority of cases, reactions are mild and can be explained by the body’s own immune response.
But monitoring systems designed to track adverse events are catching much rarer but more serious events. Now scientists need to work out if they are causally liked to the vaccine, or are just statistical anomalies – and that is not an easy task.News: Why is it so hard to investigate the rare side effects of COVID vaccines?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
A large portion of the U.S. population still doesn’t want to get the new Covid vaccine, but they might not have a choice. Powers at the federal and state level, not to mention the legal rights granted to employers under U.S. labor law, may make it impossible for Americans to escape inoculation against the coronavirus.
The dream of mRNA persevered in part because its core principle was tantalizingly simple, even beautiful: The world’s most powerful drug factory might be inside all of us.
Like so many breakthroughs, this apparent overnight success was many decades in the making. More than 40 years had passed between the 1970s, when a Hungarian scientist pioneered early mRNA research, and the day the first authorized mRNA vaccine was administered in the United States, on December 14, 2020. In the interim, the idea’s long road to viability nearly destroyed several careers and almost bankrupted several companies.
New York Times columnist David Brooks and Washington Post columnist Jonathan Capehart join Judy Woodruff to discuss the week in politics, including Republican reluctance to get the COVID-19 vaccine, the response to violence against Asian Americans and the Atlanta attacks, and the Biden administration’s immigration policy.
