In response to the administration’s threats, Harvard has sued to block the funding freeze and persuaded a federal judge to temporarily halt the ban on enrolling international students. During a hearing in Boston on Thursday, the judge extended her order blocking the ban.Nicholas Burns, a career diplomat who served as the U.S. ambassador to China from 2021 to 2025 and now teachers at the university, said “Harvard can’t be Harvard without its international students.”“There’s a lot of collective pride at the university about who we are and the decisions we’ve made, and obviously what we want to do is make sure that international students can return to Harvard, can stay at Harvard this summer and return in September,” Burns said, adding that it is important for American students to study alongside their international peers.

Garber didn’t directly touch on the Trump administration threats Thursday. But he did get a rousing applause when he referenced the university’s global reach, noting that it is “just as it should be.”Other speakers were more direct. Speaking in Latin, salutatorian Aidan Robert Scully delivered a speech laced with references to Trump policies.

, who co-authored the journal paper and joined the FDA webcast.Prasad and Makary criticized the U.S.’s “one-size-fits-all,” contrasting it with some European countries that recommend boosters based on age, risk and other factors.
