As we learn more about #COVIDvaccine #immune response in people w/ #immunedisorders, remember that not all #immunodeficiencies are created equal. You might see in the news claims about #vaccines not working in the #immunocompromised, but that's not always true. A 🧵 One of the earliest articles showed 15% of #transplant patients were Ab positive after dose 1. This increased to 54% after dose 2, but varied by medications being taken. bit.ly/3x00nyA and bit.ly/3cmfria

I want to separately pull out this graphic from the @ASMicrobiology #COVID19 #testing paper since I think it’s *super* helpful. #RNA tests tell us if you’re infected right now (mostly, see next tweet). #Serology tells us if you were recently(ish) infected. 1st important point. RNA tests can pick up any viral RNA, whether that’s live infectious virus or garbage RNA still in your body. Also the sample might not capture RNA (say the virus is in your GI not your nose & we sample your nose). This can give false negatives.

From the @CDCgov update on #coronavirus: 110 persons under investigation in US from 26 states. Only 5 have been confirmed. @CDCgov Assay protocol for test has been published, and CDC is working to prioritize state health departments for receiving tests. Will release to other domestic/intl labs later.

Sequences from 2 US patients have been uploaded to Genbank.
