US, Hungarian scientists win Nobel Prize for research that led to Covid vaccines
Scientists Katalin Kariko of Hungary and Drew Weissman of the United States respectively won the 2023 Nobel Prize in Physiology or Medicine for discoveries enabling the development of mRNA Covid-19 vaccines, the award-giving body has announced.
“The 2023 Nobel Prize in Physiology or Medicine has been awarded to Katalin Kariko and Drew Weissman for their discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against Covid-19,” the body said on Monday
The prize, among the most prestigious in the scientific world, is selected by the Nobel Assembly of Sweden’s Karolinska Institute Medical University and also comes with 11 million Swedish crowns (about $1 million).
Kariko was senior vice president and head of RNA protein replacement at BioNTech until 2022 and has since acted as an adviser to the company. She is also a professor at the University of Szeged in Hungary and adjunct professor at the University of Pennsylvania’s Perelman School of Medicine.
Weissman is professor in vaccine research at the Perelman School.
Kariko found a way to prevent the immune system from launching an inflammatory reaction against lab-made mRNA, previously seen as a major hurdle against any therapeutic use of mRNA.
Together with Weissman, she showed in 2005 that adjustments to nucleosides, the molecular letters that write the mRNA’s genetic code, can keep the mRNA under the immune system’s radar.
‘Major impact on society’
“So this year’s Nobel Prize recognises their basic science discovery that fundamentally changed our understanding of how mRNA interacts with the immune system and had a major impact on society during the recent pandemic,” said Rickard Sandberg, member of the Nobel Assembly at Karolinska Institute
The medicine prize kicks off this year’s awards with the remaining five to be unveiled in the coming days.
The prizes, first handed out in 1901, were created by Swedish dynamite inventor and wealthy businessman Alfred Nobel, and are awarded for achievements in science, literature and peace, and in later years also for economics.
The Swedish king will present the prizes at a ceremony in Stockholm on Dec. 10, the anniversary of Nobel’s death, followed by a lavish banquet at city hall.
Last year’s medicine prize went to Swede Svante Paabo for sequencing the genome of the Neanderthal, an extinct relative of present-day humans, and for discovering a previously unknown human relative, the Denisovans.
Other past winners include Alexander Fleming, who shared the 1945 prize for the discovery of penicillin, and Karl Landsteiner in 1930 for his discovery of human blood groups.
Noor Jalal Jalali, Minister of Public Health of Afghanistan, held a meeting in Kabul with representatives of the World Health Organization, UNICEF, the World Bank, the Asian Development Bank, the European Union, the UK Foreign, Commonwealth and Development Office (FCDO), and other international organizations.
According to the ministry’s statement, representatives of these international organizations discussed the delivery of health and development services, improving the management of aid and resources in the health sector, integrating health facilities and aligning them with the new policy, providing health services in accordance with the Ministry of Public Health’s policy, strengthening the immunization and vaccination sector, delivering services based on priorities, and ensuring sustained coordination.
During the meeting, Jalali stressed the need for transparency and attention to the ministry’s priorities in order to enhance the effectiveness and impact of health services. He added that the delivery of health services must be carried out in line with the ministry’s policy and through better management of existing international assistance.
Referring to vaccination campaigns, he stated that the recent measles and polio vaccination campaign had been implemented very successfully, and emphasized that necessary preparations should be made for upcoming campaigns.
He also provided information regarding the review of the BPHS and EPHS health packages and the establishment of a standardized system through technical committees.
In this meeting, Edwin Ceniza, the WHO Representative for Afghanistan, reaffirmed the organization’s continued cooperation with the Ministry of Public Health and expressed appreciation to the ministry’s leadership for their tireless efforts to improve the health system.
Representatives of these organizations pledged to maintain effective and sustained coordination and to provide their services within the country in accordance with the policies and principles of the Ministry of Public Health.
Abdul Wali Haqqani, Deputy Minister for Health Services at the Ministry of Public Health of the Islamic Emirate of Afghanistan (IEA), has departed for Turkey on an official visit accompanied by a high-ranking delegation.
According to a statement released by the Health Ministry on Wednesday, the trip aims to acquire new health-sector expertise, assess Turkish medical and scientific institutions, meet with Turkish health and government officials, and strengthen bilateral cooperation.
During the visit, the delegation is scheduled to meet representatives from both public and private health sectors to support improvements in Afghanistan’s healthcare system and enhance coordination between the two countries, the statement added.

Polio vaccination drive launches across 17 Afghan provinces
Officials say routine vaccination remains the most effective tool for eliminating polio and have urged families to fully cooperate with health teams during the campaign.
The Ministry of Public Health has announced the launch of a major anti-polio vaccination campaign, set to begin on Monday across 17 provinces of Afghanistan.
According to Sharafat Zaman, spokesperson for the ministry, the nationwide initiative will target 7.4 million children under the age of five, delivering vaccines door-to-door to prevent the spread of the poliovirus and safeguard children’s health.
Officials say routine vaccination remains the most effective tool for eliminating polio and have urged families to fully cooperate with health teams during the campaign.
This effort forms part of the government’s ongoing strategy to protect Afghanistan’s next generation from preventable diseases and strengthen public health across the country.
This comes after the World Health Organization (WHO) recently again classified the global spread of poliovirus as a Public Health Emergency of International Concern (PHEIC), warning that the disease remains endemic in only two countries — Afghanistan and Pakistan.
The decision followed the 43rd meeting of the Polio Emergency Committee under the International Health Regulations (IHR), which convened on 1 October 2025.
According to the Committee, Afghanistan reported four new wild poliovirus type 1 (WPV1) cases so far this year, compared to 24 in Pakistan.
The Afghan cases were detected in the country’s southern and eastern regions, where transmission remains intense despite ongoing vaccination efforts.
