By comparison, about 1 in 600 people Americans have already died of covid-19 or with the infection as a contributing factor, meaning getting infected by the coronavirus is the much greater risk overall.
The problem is that the blood clots have struck younger women, whose personal risk from covid-19 is lower.
The women, all between the ages of 18 and 48, developed serious blood clots six to 13 days after getting the vaccine, the FDA said in a statement. According to the New York Times, one woman died and another is in critical condition.
That means people, especially women, who have gotten the J&J vaccine recently should be on the lookout for a severe headache, pain in the abdomen or legs, and shortness of breath. After about two weeks the risk seems to pass.
The government warned that the type of clot being seen—called a cerebral venous sinus thrombosis—is very unusual and that heparin, a common blood thinner often used to treat clots, could be dangerous in these cases. A group of advisors to the US Centers for Disease Control will meet Wednesday, April 14, to review the cases and “assess their potential significance.”
In statement, Johnson & Johnson said it was “aware of an extremely rare disorder” involving vaccine recipients and said it had decided to postpone the rollout of its vaccine in Europe.
Blot clots have also been linked to another vaccine, from AstraZeneca, which has been widely used in Europe but is not yet authorized in the US. Regulators in Europe have in some cases recommended that younger people avoid that vaccine.
Both the J&J and AstraZeneca vaccines employ an adenovirus, a supposedly harmless component. Now scientists will investigate whether the adenovirus, or another aspect of the vaccine, causes an immune reaction that is leading to the clots.
The two most widely used vaccines in the US, sold by Moderna and Pfizer, are mRNA vaccines that employ a different technology. Those vaccines often cause muscle aches and fever but haven’t been linked to blood clots.
The pause announced by the FDA is likely to curtail the use of the J&J shot at federal vaccine sites. States and hospitals can choose to keep giving it depending on the age and risk profile of the patient, although several governors, as well as the CVS and Walgreens pharmacy chains, said they would also pause the shots, the New York Times reported.
The J&J vaccine requires a single shot and is more convenient than the Moderna and Pfizer vaccines, which both require two doses. However, the company’s manufacturing was plagued by problems. Now, with concern over side effects, the role it plays in the US response may become even more limited.

The big story
California’s coming offshore wind boom faces big engineering hurdles
Research groups estimate that the costs could fall from around $200 per megawatt-hour to between $58 and $120 by 2030. That would leave floating offshore wind more expensive than solar and onshore wind, but it could still serve an important role in an overall energy portfolio.
The technology is improving as well. Turbines themselves continue to get taller, generating more electricity and revenue from any given site. Some research groups and companies are also developing new types of floating platforms and delivery mechanisms that could make it easier to work within the constraints of ports and bridges.
The Denmark-based company Stiesdal has developed a modular, floating platform with a keel that doesn’t drop into place until it’s in the deep ocean, enabling it to be towed out from relatively shallow ports.
Meanwhile, San Francisco startup Aikido Technologies is developing a way of shipping turbines horizontally and then upending them in the deep ocean, enabling the structures to duck under bridges en route. The company believes its designs provide enough clearance for developers to access any US port. Some 80% of these ports have height limits owing to bridges or airport restrictions.
A number of federal, state, and local organizations are conducting evaluations of California and other US ports, assessing which ones might be best positioned to serve floating wind projects and what upgrades could be required to make it possible.
Government policies in the US, the European Union, China, and elsewhere are also providing incentives to develop offshore wind turbines, domestic manufacturing, and supporting infrastructure. That includes the Inflation Reduction Act that Biden signed into law this summer.
Finally, as for California’s permitting challenges, Hochschild notes that the same 2021 law requiring the state’s energy commision to set offshore wind goals also requires it to undertake the long-term planning necessary to meet them. That includes mapping out a strategy for streamlining the approval process.
For all the promise of floating wind, there’s little question that ensuring it’s cost-competitive and achieving the targets envisioned will require making massive investments in infrastructure, manufacturing, and more, and building big projects at a pace that the state hasn’t shown itself capable of in the recent past.
If it can pull it off, however, California could become a leading player in a critical new clean energy sector, harnessing its vast coastal resources to meet its ambitious climate goals.
How Twitter’s “Teacher Li” became the central hub of China protest information
It’s hard to describe the feeling that came after. It’s like everyone is coming to you and all kinds of information from all over the world is converging toward you and [people are] telling you: Hey, what’s happening here; hey, what’s happening there; do you know, this is what’s happening in Guangzhou; I’m in Wuhan, Wuhan is doing this; I’m in Beijing, and I’m following the big group and walking together. Suddenly all the real-time information is being submitted to me, and I don’t know how to describe that feeling. But there was also no time to think about it.
My heart was beating very fast, and my hands and my brain were constantly switching between several software programs—because you know, you can’t save a video with Twitter’s web version. So I was constantly switching software, editing the video, exporting it, and then posting it on Twitter. [Editor’s note: Li adds subtitles, blocks out account information, and compiles shorter videos into one.] By the end, there was no time to edit the videos anymore. If someone shot and sent over a 12-second WeChat video, I would just use it as is. That’s it.
I got the largest amount of [private messages] around 6:00 p.m. on Sunday night. At that time, there were many people on the street in five major cities in China: Beijing, Shanghai, Chengdu, Wuhan, and Guangzhou. So I basically was receiving a dozen private messages every second. In the end, I couldn’t even screen the information anymore. I saw it, I clicked on it, and if it was worth posting, I posted it.
People all over the country are telling me about their real-time situations. In order for more people not to be in danger, they went to the [protest] sites themselves and sent me what was going on there. Like, some followers were riding bikes near the presidential palace in Nanjing, taking pictures, and telling me about the situation in the city. And then they asked me to inform everyone to be cautious. I think that’s a really moving thing.
It’s like I have gradually become an anchor sitting in a TV studio, getting endless information from reporters on the scene all over the country. For example, on Monday in Hangzhou, there were five or six people updating me on the latest news simultaneously. But there was a break because all of them were fleeing when the police cleared the venue.
On the importance of staying objective
There are a lot of tweets that embellish the truth. From their point of view, they think it’s the right thing to do. They think you have to maximize the outrage so that there can be a revolt. But for me, I think we need reliable information. We need to know what’s really going on, and that’s the most important thing. If we were doing it for the emotion, then in the end I really would have been part of the “foreign influence,” right?
But if there is a news account outside China that can record what’s happening objectively, in real time, and accurately, then people inside the Great Firewall won’t have doubts anymore. At this moment, in this quite extreme situation of a continuous news blackout, to be able to have an account that can keep posting news from all over the country at a speed of almost one tweet every few seconds is actually a morale boost for everyone.
Chinese people grow up with patriotism, so they become shy or don’t dare to say something directly or oppose something directly. That’s why the crowd was singing the national anthem and waving the red flag, the national flag [during protests]. You have to understand that the Chinese people are patriotic. Even when they are demanding things [from the government], they do it with that sentiment.
