Covid-19: Race To Update Vaccines For Variants
Just two months ago, the incredible performance of new vaccines from Moderna and Pfizer had people cheering for an imminent end to the pandemic. But an onslaught of fast-spreading and potentially dangerous mutations of the virus changed that.
So now, even as pharma companies ramp up production in the early stages of a massive rollout, they are racing to retool their vaccine strategies. Robert Langreth reports that booster shots could give drugmakers a lucrative new revenue stream.

Covid Vaccine: ‘What Went Wrong With U.S. Rollout’
The U.S. coronavirus rollout has been anything but smooth. States are reporting limited supply of vaccines, leading them to delay appointments and close clinics to the public. Some states lack staff and essential resources to get the job done. With little guidance from the previous White House administration on how to effectively administer vaccines, it’s up to states and local health officials to get the job done. President Joe Biden announced the administration will buy 200 million more vaccines and institute a national vaccine program to vaccinate 100 million doses in his first 100 days. But can it be done? Here’s what went wrong with the U.S. coronavirus vaccine rollout and how a new White House plans to turn things around.
Covid-19: Understanding The New Variants & New Vaccines Effectiveness
Researchers are scrambling to understand the biology of new coronavirus variants and the impact they might have on vaccine efficacy.
Around the world, concern is growing about the impact that new, faster-spreading variants of the SARS-CoV-2 virus will have on the pandemic.
In this episode of Coronapod, we discuss what these variants are, and the best way to respond to them, in the face of increasing evidence that some can evade the immunity produced by vaccination or previous infection.

Covid Vaccination Spots: ‘Disneyland To Vacci’Bus’ Around The World (Video)
As the rollout of #Covid-19 vaccinations gathers pace, the mammoth task of inoculating billions of people across the globe has seen a number of unusual sites and buildings converted into #vaccination centres, from Disneyland in California, to an ancient UK cathedral and a bus converted into a mobile vaccination unit.
Covid-19: ‘How Do The Leading Vaccines Work?’
As countries like the United States and United Kingdom inoculate their residents with never-before used vaccine technology, others, including Russia, China, and India, are investing in more traditional approaches, like inactivated coronavirus vaccines. But no matter the technique, together they have the potential to create multiple lines of defense against SARS-CoV-2. Science senior correspondent Jon Cohen explains how each of these vaccines can protect us from severe illness—and what understanding the details of our immune responses could mean for the future of human trials.
