In December 2019, a new disease emerged from a seafood market in Wuhan, China. People who were infected began experiencing fever, dry cough, muscle aches and shortness of breath. The disease swept through China like wildfire and quickly spread overseas to almost every continent. We now know the virus that caused this disease, SARS-CoV-2, is […]
In late November 2023, regulatory authorities in Japan approved a new SARS-CoV-2 vaccine. Unlike earlier messenger RNA (mRNA) vaccines used to protect against COVID-19, this one relies on a technology called self-amplifying mRNA, or saRNA. Though researchers have long pursued saRNA-based vaccines, this represents the first full approval for the technology in humans and marks […]
On Thursday November 9th, 2023, Promega held its 7th Biologics Symposium at the Babraham Research Campus in Cambridge. For the first time, participants had the option to attend the event either in person or experience it via live stream, creating an inclusive and dynamic environment where the latest breakthroughs and ideas could be showcased. Moreover, […]
The first monoclonal antibody (mAb) was produced in a lab 1975, and the first therapeutic mAb was introduced in the United States to prevent kidney transplant rejection in 1986. The first mAb used in cancer treatment the anti-CD20 mAb, rituximab, was used to treat non-Hodgkin’s lymphoma and chronic lymphocytic leukemia. Today therapeutic mAbs have become […]
Last updated April 28, 2023 COVID-19 is still a global pandemic. Around the world, as of 5:40pm CEST, 26 April 2023, there have been 764,474,387 cumulative confirmed cases of COVID-19, including 6,915,655 deaths, reported to the World Health Organization. As of 24 April 2023, a total of 13,325,228,015 vaccine doses have been administered. The adoption […]
In the rapidly shifting context of a pandemic, public health officials need a way to quickly assess how vaccinations perform in changing situations. One approach is to identify correlates of protection, or biological markers that correlate with a certain level of protection from disease. This tool is used to assess the design and formulation of […]
Before the respiratory virus SARS-CoV-2 ever emerged, Tom Friedrich was already studying how viruses evolve to cause pandemics. His PhD training focused on how HIV adapts to escape detection by the immune system. Since opening his lab at the University of Wisconsin—Madison in 2008, he’s studied how viruses like influenza and Zika overcome evolutionary barriers […]
COVID-19 cases are now being identified primarily among unvaccinated individuals, according to data from the US Centers for Disease Control and Prevention (CDC). However, there has been increasing concern about so-called breakthrough infections among fully vaccinated individuals, particularly after the emergence of the SARS-CoV-2 Delta variant. What is a breakthrough infection? The CDC defines it […]
Globally, there have been over 5 million deaths attributed to COVID-19 since the start of the pandemic. Throughout the ongoing battle against SARS-CoV-2, researchers have been studying the viral lineage and the variants that are emerging as the virus evolves over time. The more opportunities that the virus has to replicate (i.e., the more people […]
As we’ve all learned from the current global COVID-19 pandemic, coronaviruses are generally bad news. Among the four genera of coronaviruses, the betacoronavirus genus has been especially notorious. In the past 20 years, three highly pathogenic betacoronaviruses, MERS-CoV, SARS-CoV and SARS-CoV-2 have resulted in serious pandemics. All three of these viruses originated from bats, highlighting […]
