Why Are They Asking This?

On Tuesday, PJ Media posted an article about a new question the Red Cross is asking blood donors.

The article notes:

How curious then, that the Red Cross is not only screening applicants for their vax status but also requiring them to undergo additional scrutiny if they self-report COVID vaccination: “Have you EVER had a Coronavirus (COVID-19) vaccine? If you answer YES to the question, please call 1-800-RED CROSS… before coming in to donate to determine if this will affect your eligibility.”

The article includes the following screenshot:

There is a ‘context’ note added at the end of the Tweet. The context note says:

They ask this question to make sure you haven’t received a self-replicating vaccine; and if you have, there is a two-week wait.

Most Covid vaccines are not replicating, and do not require a waiting period.

Generally speaking, when you give blood, you are not asked about vaccines. Why is this vaccine different?
