You still need to inform the blood center beforehand by submitting a travel form. You still won't be able to just show up and give blood: https://www.redcrossblood.org/content/dam/redcrossblood/documents/travel_for-2.pdf

It's better to just use RapidPass to be certain: https://www.redcrossblood.org/donate-blood/manage-my-donations/rapidpass.html

>Those previously deferred under former vCJD criteria will need to be reinstated before being able to donate. Reinstatement of previously deferred donors began October 3 and it’s estimated it will take several months to complete as it affects hundreds of thousands of donors. Individuals will be informed when their reinstatement is complete. Individuals may also contact the Red Cross Donor and Client Support Center at 1-866-236-3276 for information about donor eligibility.
