Keeping it cool at BCCDC: It's ice cream appreciation day for @cdcofbc laboratory staff. @ubcpathology microbiologists Drs. Prystajecky, Morshed, Jassem, Sekirov, and Krajden handed out ice cream with surprise guest Dr. Bonnie Henry who stopped by to show her appreciation too!

Our #Covid_19 single-dose vaccine effectiveness study is out; overall mRNA and ChAdOx1 VE was 74% and 59% against infection and 86% and 94% and against hospitalization academic.oup.com/jid/advance…

We validated an assay that can simultaneously detect antibodies against sars-cov-2 and other coronaviruses to better understand exposure influences on immunity after #COVID-19 or vaccination, check it out (pre-proof), written by @fangfang__li authors.elsevier.com/sd/arti…

VE holding up to 8+ months looking at Ontario data...do we need more boosters right now in 🇨🇦 or more vaccine in #LMICs @DrJeffKwong @ICESOntario #COVID19 #vaccines

Pre-preprint data: in Ontario, VE of mRNA vaccines seems to be holding up 8+ months after the 2nd dose, especially vs hospitalization or death (>90%). Vs infection, the glass still appears to be ~3/4 full. @ICESOntario 1/

Very excited for @xuan_l1 's first PhD paper to be out in @mSystemsJ. TLDR: multiplex tiling PCR primer design and wastewater matrix impacted sensitivity of sequencing SARS-CoV VoCs. Also frequency of VoCs in WW correlated strongly with clinical cases. bit.ly/3piTvvG

BC COVID-19 vaccine effectiveness results show that two doses of #COVID19 vaccines provide strong protection, including against the #Delta variant, and prevent about 95% of hospitalizations. Protection is maintained for at least four months. Read more: ow.ly/Yiyi50GiX17

Latest on single dose vaccine effectiveness! While 1 dose of a ChAdOx1 had less protection (60%) against infection, just one dose of any vaccine reduced the hospitalization risk by more than 80%. #skowronski @spphubc @CDCofBC @UBCmedicine medrxiv.org/content/10.1101/…

We started our monitoring of SARS-CoV-2 on @UBC campus this week! Here is @xuan_l1 deploying our COSCa passive samplers (developed by @C_L_Sweeney 🇨🇦). Keep masking up, and remember to get both shots 💉! @CDCofBC @ubccivil @NatPrysta @Mel_Glier @DrT1973

This important work was only possible due to the early and generous support from @GenomeBC, #CanCOGEN, @GenomeCanada & @PHSAofBC

B.C. accounts for 11% of Canada’s COVID-19 cases but is responsible for 32% (38,868) of Canada's uploaded SARS-CoV-2 genomes to @GISAID. This helps researchers understand how the pandemic spreads. Dr. Natalie Prystajecky of @CDCofBC & @UBCpathology has directed this great effort!
