 FK-TODO:
-- Prüfe, ob die VAERS_ID wirklich eindeutig ist.
+- "I would suggest that you filter the vax table first for just C19 vaccines, and for just first dose.
+  Then carry out the analysis as before.
+  Repeat for second dose and third dose separately. The cumulative effect will then appear.
+  It should be analysed separately anyway, because adverse reactions increase with each dose."
+  # 1. filter the vax table first for just C19 vaccines
+  # 2. and for just n-tn (n \in {1, 2, 3}) dose => VAERSDATA --> VAERSVAX ist 1:1-Beziehung statt 1:n und kann einfacher in eine einzige Tabelle gemergt werden
+  # 3. filter for manufacturer
+- Prüfe, ob die VAERS_ID wirklich eindeutig ist. Antwort: VAERS_ID ist in der VAERSVAX-Tabelle nicht eindeutig, da es mehrere Impfungen pro Person geben kann.
 - VAX_LOT-Spalte normalisieren, d.h. mindestens toUpperCase() darauf anwenden
 - Format des jeweiligen Herstellers berücksichtigen und "verschmutzte" Einträge säubern, denn sie stellen alle dieselbe Charge dar:
