GPs did not recommend the seasonal influenza vaccine. Confidence in the population correlated with confidence among GPs. A study of vaccine-hesitant U.S. college students found that after they interviewed survivors of vaccine-preventable diseases, they were more likely to become pro-vaccine than a control group. Parties opposed to the use of vaccines frequently refer to data obtained from the US Vaccine Adverse Event Reporting System (VAERS). This is a database of reports of issues associated with vaccines which has been useful for investigation, but since any claim can be entered into the VAERS, its data is not all reliable. Dubious claims about vaccines against hepatitis B, HPV and other diseases have been propagated based on misuse of data from VAERS.
