I'm struggling to find an appropriate answer. In the sentence below, 'persuade' confuses me since it seems to me this word should take a -to before itself.
Researchers have been looking for ways to help governments persuade vaccine-hesitant people for some time.
Mine:
Researchers have been looking for ways to help governments to persuade vaccine-hesitant people for some time.
Could somebody explain to me why this is the case here?
