Happy Godzilla Day to all those who celebrate. Give a little love to the man-in-rubber-suit 50s-70s era Godzilla we all love - either openly or secretly! #GodzillaDay

Found this book in my department mailbox yesterday. No envelope, no shipping information, no note and I was the only person to receive this "gift". Clearly, someone needs to come to my lecture on the origin and evolution of the COVID-19 pandemic to get educated on the facts.

Congratulations to Jerome Edwards on defending his PhD thesis on mechanisms driving the attenuation of Live attenuated measles vaccine virus replication. Jerome did great things and is yet another example of Diane Griffin's mentoring. @johnshopkinsmmi.bsky.social @johnshopkinssph.bsky.social

Our two summer students wrapped up their stays in the laboratory with posters on the influenza viruses that circulated this past year. One preprint is up and another is coming. lots of thanks to @ceirrnetwork.bsky.social and @johnshopkinsmmi.bsky.social for support and collaborations!

Second, C.3re escaped influenza vaccine induced serum neutralizing antibody in a very significant way.

Second, C.3re escaped influenza vaccine induced serum neutralizing antibody in a very significant way.
Why is this important? First, the C.3re infections skewed to a much younger age group than the C.5 infections that had been occurring earlier in the influenza season.

Finally, we named it C.3re because it’s a reassortant virus between a C.5.1 and a C.3 clade virus, with a little uncertainty about where the NS segment came from

It also encodes an NA with some mutations at known antibody epitopes and near the enzyme active site

The first interesting thing about this IBV variant, C.3re, is that it has a mutation that reintroduces a N-linked glycosylation site at 197 of HA – a site known to mask a neutralizing antibody epitope

Worked on a manuscript with @meghandavisdvm.bsky.social this morning, and now I see her receive the prestigious Stebbins award for public health teaching and contributions @johnshopkinssph.bsky.social . Congratulations!!!

Always a thrill to see the smiling faces of our @johnshopkinssph.bsky.social graduates...even on a rainy, chilly day. 61 countries represented and over 1200 different degrees being conferred.

We got a chance to celebrate our gradating ScM students from @JohnsHopkinsMMI this past week. Got to work with these 5 fantastic students and two more who I didn't get pics with.

I remember Josh asking me if a bottle of Scotch had enough alcohol to kill viruses...my reply was something like "i can think of better things to do with a bottle of Scotch then disinfect things..."

I do love CDC's FluView. looks like influenza like illness is dropping for the second (and hopefully last) time this year. its been quit an influenza season...

On a lighter, my lab decided to do a journal club focused on a paper from my PhD thesis since its my birthday. We discussed "data not shown" and a lack of stats in some figures 🫢. Today, we ask similar questions with other viruses which was an interesting contrast pubmed.ncbi.nlm.nih.gov/8553534/
