Interesting note, depending on the enemedia source, some stories are recommending that anyone who experienced side effects after vaccination defer donation.
Example...
From your link....
Here are the only exceptions that require deferral time:
If you received one of the early test vaccines used in clinical trials
If you don’t know the name of the vaccine you received
If you experienced side effects from your shot
There is a FReeper who was in the clinical trials...apologies, I can’t recall their name. I guess they’re aware they cannot donate blood.
Is a sore arm, rash or general malaise a ‘side effect’? I wonder if there’s a list of accepted side effects, per Red Cross.
