Drew Weissman, Jewish immunologist, wins Nobel Prize for his work on Covid vaccines
(JTA) — Drew Weissman, a Jewish scientist who identified the technology that made possible the mRNA vaccines against COVID-19, has won the 2023 Nobel Prize in medicine. Weissman shared the prize with Katalin Kariko, his Hungarian-born research partner at the University of Pennsylvania.
Kariko and Weissman’s story of collaboration became famous in 2020 when the technology they had started experimenting with more than two decades earlier allowed the swift creation effective vaccines against the crippling pandemic.
The pair first encountered each other while photocopying research papers in 1998 and realized they were working on related topics. Kariko, who had been a low-level researcher for years, was trying to prove that messenger RNA, the genetic material that tells cells what to do, could be programmed. Weissman, a physician who previously worked under Dr. Anthony Fauci, later the U.S. COVID czar, at the National Institutes of Health, was working on a vaccine against HIV.
They teamed up and, in 2005, published a paper showing that mRNA could in fact be altered to instruct cells to take certain actions. But their breakthrough was widely overlooked for decades until it became clear that it could be used to take action against COVID-19, which was killing hundreds of thousands of people and crippling the global economy. Their technology fueled both the Pfizer and Moderna vaccines, which arrived with unusual speech and effectiveness in late 2020 and together have been administered millions of times.
“Through their groundbreaking findings, which have fundamentally changed our understanding of how mRNA interacts with our immune system, the laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times,” the Nobel Prize committee said in announcing the award.
Weissman is the son of a Jewish father and non-Jewish mother who grew up celebrating Jewish holidays at home, he told the Philadelphia Jewish Exponent in 2021. Together with his wife Mary Ellen, who grew up in a more observant Jewish home, he sent his children to Hebrew school at Temple Beth Hillel/Beth El, a Conservative synagogue in suburban Philadelphia. Mary Ellen Weissman is heavily involved in Momentum, which seeks to engage Jewish women with Israel, and together with her husband has spoken to and donated to the organization.
Drew Weissman told the Exponent that his personal religious outlook was not specifically Jewish. ““I’m more of a Daoist, in that point of view that I think that Earth, nature is the supreme — the main component of life,” he said. “And that’s what needs to be celebrated.”
About a quarter of Nobel laureates in medicine over time have had one or more Jewish parents, according to Jinfo.org, a website that meticulously documents the Jewish lineage of prize winners across all fields. The site, which was updated swiftly to include Weissman, says that nearly 40% of U.S. Nobel laureates in medicine have been Jewish.

UN Security Council Meets on Iran as Russia, China Push for a Ceasefire

The U.N. Security Council met on Sunday to discuss US strikes on Iran’s nuclear sites as Russia, China and Pakistan proposed the 15-member body adopt a resolution calling for an immediate and unconditional ceasefire in the Middle East.
It was not immediately clear when it could be put to a vote. The three countries circulated the draft text, said diplomats, and asked members to share their comments by Monday evening. A resolution needs at least nine votes in favor and no vetoes by the United States, France, Britain, Russia or China to pass.
The US is likely to oppose the draft resolution, seen by Reuters, which also condemns attacks on Iran’s nuclear sites and facilities. The text does not name the United States or Israel.
“The bombing of Iranian nuclear facilities by the United States marks a perilous turn in a region that is already reeling,” U.N. Secretary-General Antonio Guterres told the Security Council on Sunday. “We now risk descending into a rathole of retaliation after retaliation.”
“We must act – immediately and decisively – to halt the fighting and return to serious, sustained negotiations on the Iran nuclear program,” Guterres said.
The world awaited Iran’s response on Sunday after President Donald Trump said the US had “obliterated” Tehran’s key nuclear sites, joining Israel in the biggest Western military action against the Islamic Republic since its 1979 revolution.
U.N. nuclear watchdog chief Rafael Grossi told the Security Council that while craters were visible at Iran’s enrichment site buried into a mountain at Fordow, “no one – including the IAEA – is in a position to assess the underground damage.”
Grossi said entrances to tunnels used for the storage of enriched material appear to have been hit at Iran’s sprawling Isfahan nuclear complex, while the fuel enrichment plant at Natanz has been struck again.
“Iran has informed the IAEA there has been no increase in off-site radiation levels at all three sites,” said Grossi, who heads the International Atomic Energy Agency.
Iran requested the U.N. Security Council meeting, calling on the 15-member body “to address this blatant and unlawful act of aggression, to condemn it in the strongest possible terms.”
Israel‘s U.N. Ambassador Danny Danon said in a statement on Sunday that the U.S. and Israel “do not deserve any condemnation, but rather an expression of appreciation and gratitude for making the world a safer place.”
Danon told reporters before the council meeting that it was still early when it came to assessing the impact of the U.S. strikes. When asked if Israel was pursuing regime change in Iran, Danon said: “That’s for the Iranian people to decide, not for us.”

Israel has rejected a European Union report saying it may be breaching human rights obligations in Gaza and the West Bank as a “moral and methodological failure,” according to a document seen by Reuters on Sunday.
The note, sent to EU officials ahead of a foreign ministers’ meeting on Monday, said the report by the bloc’s diplomatic service failed to consider Israel’s challenges and was based on inaccurate information.
“The Foreign Ministry of the State of Israel rejects the document … and finds it to be a complete moral and methodological failure,” the note said, adding that it should be dismissed entirely.

Pope Leo Urges International Diplomacy to Prevent ‘Irreparable Abyss’

Pope Leo on Sunday said the international community must strive to avoid war that risks opening an “irreparable abyss,” and that diplomacy should take the place of conflict.
US forces struck Iran’s three main nuclear sites overnight, joining an Israeli assault in a major new escalation of conflict in the Middle East as Tehran vowed to defend itself.
“Every member of the international community has a moral responsibility: to stop the tragedy of war before it becomes an irreparable abyss,” Pope Leo said during his weekly prayer with pilgrims.
“No armed victory can compensate for the pain of mothers, the fear of children, the stolen future. Let diplomacy silence the weapons, let nations chart their future with peace efforts, not with violence and bloody conflicts,” he added.
“In this dramatic scenario, which includes Israel and Palestine, the daily suffering of the population, especially in Gaza and other territories, risks being forgotten, where the need for adequate humanitarian support is becoming increasingly urgent,” Pope Leo said.
