Hint: full name refers to first, last; Yaz 28 Day Pack refers to DESCRIPTION = 'Yaz 28 Day Pack' from medications; started taking in 2011 refers to START like '2011%';

Question: What are the full names of the patients who started taking Yaz 28 Day Pack in 2011?

assistant: SELECT DISTINCT T1.first, T1.last, T1.suffix FROM patients AS T1 INNER JOIN medications AS T2 ON T1.patient = T2.PATIENT WHERE T2.DESCRIPTION = 'Yaz 28 Day Pack' AND strftime('%Y', T2.START) = '2011'
