Of the respondents, 45.2% of the physicians stated that biosimilar drugs are not as effective as biological reference drugs, and 35.9% thought that they aren't safe.

Nurses’ Knowledge and Attitudes towards Biosimilar Medicines as Part of Evidence-Based Nursing Practice—International Pilot Study within the Project Biosimilars Nurses Guide Version 2.0

“…Gökdemir et al showed that the general knowledge of doctors about biosimilar medicines was low, and that they had doubts about the effectiveness and safety of biosimilar medicines, which may be related to the lack of knowledge. Organized training programs in this area may raise the level of knowledge and positively influence the opinions and attitudes of doctors towards biosimilar medicines [ 14 ]. A cross-sectional study by Demir-Dora et al of 228 medical students showed that the medical students had insufficient knowledge about biosimilar medicines.…”
