Recent preprint reporting that 24/24 (100%) people form Singapore infected by SARS-1 in 2003 have pre-existing T-cell immunity against #SARSCoV2, but more surprisingly 9/18 (50%) with no exposure to SARS-1

A key piece of the #COVID19 #SARSCoV2 origin puzzle emerges: where did the virus's unusual spike protein RBD—the receptor-binding domain that engages human ACE2 protein and allows the virus to

I'm afraid this is a naive view on the virulence / transmissibility tradeoff in pathogens. A reduction in virulence is only expected to happen in strictly vertically transmitted pathogens (e.g.

There have been claims that #COVID19 has acquired mutations leading to more transmissible strains. We formally tested whether this was the case using 15,000 #SARSCoV2 genomes from all over the

I've seen arguments aired that #SARSCoV2 will 'weaken' because it 'pays a cost' by hurting its host. I'm afraid this is too simplistic and in fact incorrect. We cannot predict

Preliminary results from @hendrikstreeck et al:15% of population in Heinsberg (Germany) have evidence of past or current infection with #SARSCoV2.Based on ~500 people from 400 households (out of a representative

Is London’s #SARSCoV2 seroprevalence really 17%? Has anybody seen the data? #COVID19 Here’s the excerpt

To understand the fibs and elisions Team Apocalypse is now using in its rearguard action to keep lockdowns alive, I want to run through this much retweeted thread from a

#SARSCoV2 hospitalizations and deaths are rising fast across Europe and politicians face the difficult task to find measures that work while minimizing disruption. People will use tracing statistics to argue

again, this says absolutely *nothing* about lasting *immune memory* to #SARSCoV2. if you have memory T cells spin up immediately upon a second infection & cause existing B cells to

Over the last weeks, a substantial amount of new evidence has become available about immunity to #SARSCoV2. This information can be difficult to process and integrate. As such I felt

Our paper about #SARSCoV2-specific #tcell immunity in cases of #COVID19 and #SARS, and uninfected controls is now out, peer-reviewed and published in @nature! https://www.nature.com/articles/s41586-020-2550-z3 take-home messages:(1/5) 1) In
