June 29, 2024

In his weekly clinical update, Dr. Griffin discusses RSV vaccination recommendations and revisions to guidelines before reviewing the recent statistics on SARS-CoV-2 infection, data suggesting that individuals with high HLA-DQA2 expression (MHC class II) are better at preventing the onset of a sustained viral infection, how moderate coffee intake can reduce risk of COVID-19 severity but cannabis use resulted in more severe disease but reduced risk of mortality, where to find PEMGARDA, if statin use prevented severe COVID-19, the benefit of administering nirmatrelvir and ritonavir after 5 days, convalescent plasma, what do when healthcare workers succumb to SARS-CoV-2 infection, if fecal microbiota transplants aid in recovery from COVID-19, and the definition of characteristics and clinical patterns for the diagnosis of long COVID.
