Due to the shutdown, NIH cancelled >370 study sections, impacting >24,000 applications Rescheduled meetings will only discuss 30-35% of applications, have simplified summary statements (no narrative paragraph), and a new category - "competitive but ND" https://t.co/GL6DN31uue

π‘οΈ Insights from #ESWI2025! Dr. @nancyleung_hk presented a meta-analysis linking HAI titers of 40 to 46% protection against influenza #FluVaccine π Vaccine-induced and naturally acquired antibodies showed similar protection; age-specific & cross-protection data remain limited

In new study led by @CKikawa, we provide near real-time data on human neutralizing antibody landscape to influenza by measuring ~26,000 titers to >100 recent viral strains. Data can inform vaccine selection & evolutionary/epidemiological modeling. https://t.co/rthJdShpwP

The hemagglutinin of human influenza virus evolves rapidly to erode neutralizing antibody immunity. Twice per year, new vaccine strains are selected with the goal of providing maximum protection...

Our paper on comparing impact of prior repeated flu vaccination on breadth of influenza H3 antibody response between enhanced flu vaccines is out - the gist is it does have differential impact. I would urge everyone studying flu antibody breadth to read it

Given the constant antigenic evolution of influenza viruses, antibody breadth may better indicate the protection potential of vaccines. We found that enhan

Possibly useful little #Rstats trick: edit(names(iris)) will create a popup with the R code for the character vector containing the column names of your data frame that you can copy and paste, e.g. c("Sepal.Length", "Sepal.Width", "Petal.Length", "Petal.Width", "Species")

It was very nice to be back in Guangzhou after the pandemic to meet old and new friends, to deliver a talk on respiratory virus transmission for them and also learn from their current work across disciplines

"Partnerships in feedback require reduction in power-differentials w teachers relinquishing some power & students taking increased responsibilities. Encouraging students to take part in dialogic interaction is a significant aspect of this ceding of power"

Feedback processes are difficult to manage, and the accumulated frustrations of teachers and students inhibit the learning potential of feedback. In this conceptual paper, challenges to the develop...
