COVID-19 Vaccine Update

Iโ€™ve been wanting to give an update on vaccines, so this will be a large post giving an update on the recent happenings.   ๐— ๐—ผ๐—ฑ๐—ฒ๐—ฟ๐—ป๐—ฎ: Reminder that this is an mRNA vaccine, requiring cold storage at -20C. Today they released (by press) their primary efficacy data that showed of 196 COVID-19 cases, of which 185

Re-infection Take 2

I want to quickly write a post on the recent case of re-infection coming out of the US. Specifically about the re-infection in a 25-yr old <2 months later, with worse symptoms second time around. Genetic discordance between the two infections was greater than explained by short-term in vivo evolution, ie, presumably two separate infections.

Transmission Risk as a Continuum

Iโ€™ve written before how risk of exposure to SARS-CoV-2 (the virus that causes Covid-19) is a continuum and that there are no exact risk thresholds for say duration of contact or appropriate distance. For instance, wearing a mask reduces risk but doesnโ€™t eliminate it. It is the same with distancing. 6ft may not be sufficient

Unmasking the Mask Debate

I kid. In fact, this post will not be on whether masks are useful or not. Because we have ample evidence to show that masks, when used appropriately, reduces the transmission of SARS-CoV-2 (the virus that causes Covid-19). Instead, today I want to spend some time discussing what kinds of masks are effective, and what
