Our past couple of posts dealt with the omicron outbreaks at colleges and in pro sports.
Those venues share a common behavioral trait: practically all of the college students and athletes are fully vaccinated … yet, omicron is spreading fast enough that students are being sent home (potentially to spread the virus there) and sporting events are being postponed or cancelled.
In this week’s speech, Biden — a bit more restrained than usual — repeatedly took shots (pun intended) on the the folks who are unvaccinated … still implying that the roughly 1/4 of adults who are unvaccinated are the predominant cause of the spread.
=============
So, the question I’d like some reporter to ask Biden, Psaki or Fauci is:
College campuses are relatively contained and controlled environments.
College administrators have mandated vaccinations (reportedly with >98% compliance) and enforced strong mitigation practices, including masking.
So, how do you explain the surge of covid cases on college campuses?
============
That’s not intended as an anti-vax question.
I’m both fully vaccinated (i.e. 2 shots) and “boosted”, so I don’t take Biden’s admonition personally.
But, I want to understand risks of my catching and transmitting the virus.
============
P.S. For the “textbook” answer to the question, see: Colleges hit by surge in covid cases…
The essence of the answer: Waning vaccine effectiveness among “cohorts” of students who got vaccinated at approximately the same time … right before the school year started.
