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.

Iran Says It Has Replaced Air Defenses Damaged in Israel War

Iran has replaced air defenses damaged during last month’s conflict with Israel, Iran’s Defah Press news agency reported on Sunday quoting Mahmoud Mousavi, the regular army’s deputy for operations.
During the conflict in June, Israel’s air force dominated Iran’s airspace and dealt a heavy blow to the country’s air defenses while Iranian armed forces launched successive barrages of missiles and drones on Israeli territory.
“Some of our air defenses were damaged, this is not something we can hide, but our colleagues have used domestic resources and replaced them with pre-arranged systems that were stored in suitable locations in order to keep the airspace secure,” Mousavi said.
Prior to the war, Iran had its own domestically-made long-range air defense system Bavar-373 in addition to the Russian-made S-300 system. The report by Defah Press did not mention any import of foreign-made air defense systems to Iran in past weeks.
Following limited Israeli strikes against Iranian missile factories last October, Iran later displayed Russian-made air defenses in a military exercise to show it recovered from the attack.

Calm Reported in Syria’s Sweida, Damascus Says Truce Holding

Residents reported calm in Syria’s Sweida on Sunday after the Islamist-led government announced that Bedouin fighters had withdrawn from the predominantly Druze city and a US envoy signaled that a deal to end days of fighting was being implemented.
With hundreds reported killed, the Sweida bloodshed is a major test for interim President Ahmed al-Sharaa, prompting Israel to launch airstrikes against government forces last week as it declared support for the Druze. Fighting continued on Saturday despite a ceasefire call.
Interior Minister Anas Khattab said on Sunday that internal security forces had managed to calm the situation and enforce the ceasefire, “paving the way for a prisoner exchange and the gradual return of stability throughout the governorate.”
Reuters images showed interior ministry forces near the city, blocking the road in front of members of tribes congregated there. The Interior Ministry said late on Saturday that Bedouin fighters had left the city.
US envoy Tom Barrack said the sides had “navigated to a pause and cessation of hostilities”. “The next foundation stone on a path to inclusion, and lasting de-escalation, is a complete exchange of hostages and detainees, the logistics of which are in process,” he wrote on X.
Kenan Azzam, a dentist, said there was an uneasy calm but the city’s residents were struggling with a lack of water and electricity. “The hospitals are a disaster and out of service, and there are still so many dead and wounded,” he said by phone.
Another resident, Raed Khazaal, said aid was urgently needed. “Houses are destroyed … The smell of corpses is spread throughout the national hospital,” he said in a voice message to Reuters from Sweida.
The Syrian state news agency said an aid convoy sent to the city by the government was refused entry while aid organized by the Syrian Red Crescent was let in. A source familiar with the situation said local factions in Sweida had turned back the government convoy.
Israeli public broadcaster Kan reported on Sunday that Israel sent urgent medical aid to the Druze in Sweida and the step was coordinated with Washington and Syria. Spokespeople for Prime Minister Benjamin Netanyahu, the Foreign Ministry and the military did not immediately respond to requests for comment.
The Druze are a small but influential minority in Syria, Israel and Lebanon who follow a religion that is an offshoot of a branch of Shi’ite Islam. Some hardline Sunnis deem their beliefs heretical.
The fighting began a week ago with clashes between Bedouin and Druze fighters. Damascus sent troops to quell the fighting, but they were drawn into the violence and accused of widespread violations against the Druze.
Residents of the predominantly Druze city said friends and neighbours were shot at close range in their homes or in the streets by Syrian troops, identified by their fatigues and insignia.
Sharaa on Thursday promised to protect the rights of Druze and to hold to account those who committed violations against “our Druze people.”
He has blamed the violence on “outlaw groups.”
While Sharaa has won US backing since meeting President Donald Trump in May, the violence has underscored the challenge he faces stitching back together a country shattered by 14 years of conflict, and added to pressures on its mosaic of sectarian and ethnic groups.
COASTAL VIOLENCE
After Israel bombed Syrian government forces in Sweida and hit the defense ministry in Damascus last week, Prime Minister Benjamin Netanyahu said Israel had established a policy demanding the demilitarization of territory near the border, stretching from the Israeli-occupied Golan Heights to the Druze Mountain, east of Sweida.
He also said Israel would protect the Druze.
The United States however said it did not support the Israeli strikes. On Friday, an Israeli official said Israel agreed to allow Syrian forces limited access to the Sweida area for two days.
A Syrian security source told Reuters that internal security forces had taken up positions near Sweida, establishing checkpoints in western and eastern parts of the province where retreating tribal fighters had gathered.
On Sunday, Sharaa received the report of an inquiry into violence in Syria’s coastal region in March, where Reuters reported in June that Syrian forces killed 1,500 members of the Alawite minority following attacks on security forces.
The presidency said it would review the inquiry’s conclusions and ensure steps to “bring about justice” and prevent the recurrence of “such violations.” It called on the inquiry to hold a news conference on its findings – if appropriate – as soon as possible.
The Syrian Network for Human Rights said on July 18 it had documented the deaths of at least 321 people in Sweida province since July 13. The preliminary toll included civilians, women, children, Bedouin fighters, members of local groups and members of the security forces, it said, and the dead included people killed in field executions by both sides.
The Syrian Observatory for Human Rights, another monitoring group, has reported a death toll of at least 940 people.
Reuters could not independently verify the tolls.

Pope Leo called for an end to the “barbarity of war” on Sunday as he spoke of his profound pain over an Israeli strike on the sole Catholic church in Gaza.
Three people died and several were injured, including the parish priest, in the strike on the Holy Family Church compound in Gaza City on Thursday. Photos show its roof has been hit close to the main cross, scorching the stone facade, and shattering windows.
Speaking after his Angelus prayer, Leo read out the names of those killed in the incident.
“I appeal to the international community to observe humanitarian law and respect the obligation to protect civilians as well as the prohibition of collective punishment, of indiscriminate use of force and forced displacement of the population,” he said.
