Transmission

This article says that, starting today, COVID-positive people (basically) in Alberta will need to stay in their home, but the household members will not be required to quarantine as well. Contact tracers also will not notify the contacts of the positive people: the infect are now responsible for telling them.

Starting on 16 August, isolation following a positive test will be recommended but not mandatory.

This seems like a stunningly, gob-smackingly bad idea.

The Pfizer Q2 earnings report is interesting to see all the many vaccines and treatments which are in the pipeline. Highlights include an mRNA flu vax, a Lyme Disease vax, an RSV vax (<- one of the more common “common cold” viruses), a breast cancer drug, gene therapy for hemophilia, and gene therapy for muscular dystrophy.
