I don't have any personal opinion on this question, but it has been at the back of my mind for some time: how long do you have to wait once you have given blood, until you can donate again?
My dad has been donating for years and he says that sixteen weeks is the absolute minumum as blood replenishes quickly.
However, I heard somewhere else that you have to wait 15 years. I find this a bit unbelievable, but what is the exact waiting time, and does it differ around the globe? Is there any set minumum number of weeks/months/years worldwide?

It is definitely not 15 years or anything like, this is nonsense.
It does differ from place to place, but 6 months is the longest interval I have heard of.
In the UK you are required to wait at least 12 weeks, but 16 weeks is recommended.
In America it is 56 days. (8 weeks)

Qualified donors are allowed to donate whole blood every 8 weeks (56 days). So far that is the US standard safe interval which is an ample time for the body to replenish the lost blood and iron keeping the donor's health uncompromised. The time allowed in between donation however varies in every country, some country may require longer than that period.
For "double red apheresis donors" (donating 2 units of red blood cells component only), the waiting period is 120 days before they can donate again.

FDA guidelines require a wait of at least 56 days after donating whole blood before any type of donation may be collected (plasma, platelets and/or whole blood). Donor information is not shared between different collection organizations. However, if either the volunteer blood or compensated plasma center were to discover the early donation, you could be indefinitely/permanently deferred from any future donations (due to untruthful answers on the FDA required donor questionnaire). Please do not donate until it is time. The safety of the donor is our number one concern.

In the uk
You should not give blood if:
1 You've already given blood in the last 12 weeks (normally, you must wait 16 weeks).
