The vaccines made by Pfizer-BioNTech and Moderna set off a persistent immune reaction in the body that may protect against the coronavirus for years, scientists reported on Monday.
The findings add to growing evidence that most people immunized with the mRNA vaccines may not need boosters, so long as the virus and its variants do not evolve much beyond their current forms — which is not guaranteed. People who recovered from Covid-19 before being vaccinated may not need boosters even if the virus does make a significant transformation.
“It’s a good sign for how durable our immunity is from this vaccine,” said Ali Ellebedy, an immunologist at Washington University in St. Louis who led the study, which was published in the journal Nature.
The study did not consider the vaccine made by Johnson & Johnson, but Dr. Ellebedy said he expected the immune response to be less durable than that produced by mRNA vaccines.
Dr. Ellebedy and his colleagues reported...

The price of $TITAN fell to zero, prompting IRON Finance to call for all holders to withdraw liquidity from the pools after being hit by what it called a "bank run." Decrypt has reached out to Iron Finance for comment.
Cuban was one of those liquidity providers on QuickSwap, a decentralized exchange. He announced his involvement on June 13, tweeting: "Crypto Businesses make more sense than you think and valuing tokens is easier and makes more sense than you think."
Three days later, that investment makes less sense.
Responding to a suggestion that this was a rug pull—when founders abandon a project after cashing out—Cuban responded: "I got hit like everyone else. Crazy part is I got out, thought they were increasing their [total...
