I have heard various reasons why BC is not allowing HCWs to wear an N95 (or equivalent) while working at vaccine clinics.

But, I will submit to you that none of the arguments against N95s (or equivalents) are valid. See short thread ...
1/ Let's denote N95 (or equivalent eg. CAN-99, CN-95, KN94) = A

AND

ASTM3 surgical/medical mask = B
2/ In terms of respiratory protection (for both aerosols and droplets), A >> B.

So not allowing a HCW to wear A cannot be justified in terms of safety.

Some have used EQUITY as an excuse. If equity is an issue, then you empower all HCWs to have A.
3/ By using the equity argument, they are clearly acknowledging A > B.

Forcing HCWs to only choose B means you are putting all HCWs at risk.
4/ Let's imagine that A = B.
(For the droplet droplet dogma bitter enders who claim there is no RCT evidence demonstrating a difference).

In this scenario, there is also no justification for denying HCWs from choosing to wear A.
5/ But let's be irrational and suggest A << B.

If you want to use this argument then you need to to revise your understanding of basic physical concepts or show us evidence that A << B.
6/ So in summary, the current policy is irrational from both a scientific and logical position.

And I am taking no part in this madness. Thank you.

I support ⁦@BCNursesUnion⁩ request for appropriate PPE based on a nurses PCRA.

The PCRA does NOT require secondary approval from a supervisor to wear appropriate respiratory PPE if nurses are informed that #COVIDIsAirborne

vancouversun.com/news/local-new…
BC chose to proceed with a PCRA instead of having appropriate PPE universally for all HCWs. If the province chose this path, they should apply this consistently. Why are we still stuck with droplet dogma?
A few points to revise in the article:
- normal physiologic activities (eg. breathing) generates aerosols
- the AGMP framework is outdated and is no longer acceptable (ie inconsistent w/ principles of physics)
- transmission also occurs during the ASYMPTOMATIC stages

1/ Re: Rapid Antigen Tests - Are you confused after today's BC COVID-19 press conference?

Let's take a deeper dive
2/ Firstly, it is important to understand that not everyone infected with COVID-19 is infectious (capable of transmitting to others):

BLUE = Infected
RED = Infectious subset
3/ During the course of an infection, the viral load changes. Most people are infectious for a brief period of time:
