It is the end of February when Dana Ottmann learns that she should be vaccinated.
The 32-year-old is early, the vaccination with AstraZeneca has only just begun.
Ottmann's turn comes so quickly because she works as a psychologist in a rehabilitation clinic in Löhne, Westphalia.
On February 25th, Dana Ottmann received her vaccination.
The next morning, her mother Petra remembers, Dana had a very bad headache.
Actually, that's not unusual, says the mother.
Because Dana has had migraines since she was a child.
She is therefore being treated by a neurologist and regularly takes medication.
She reported this pre-existing condition at the vaccination center.
It was not an exclusion criterion.
But the headache is different this time.
