According to four people who’ve independently spoken to Trump about a potential pro-vaccine campaign, the former president has shown little interest in tying his name to broader efforts to get people inoculated.

When asked why Trump hadn’t done more on vaccines, Stephen Moore—who previously advised Trump on economic and coronavirus-related policy—said he didn’t have a “good answer for that.”…

According to the four sources who spoke to The Daily Beast about their phone calls and in-person conversations since early this year with Trump or former first lady Melania, the suggestions have varied considerably.

Some have suggested teaming up with the Bidens, while others have told the former president that it would be an awful idea, both on pragmatic and political levels. Several have suggested Donald and Melania Trump star in public service announcements and others videos, such as those featuring highly visible conservative influencers. Others have pitched the former president on dedicating entire interviews and whole speeches to the topic, making appearances at related venues with doctors, prominent Republicans, or pro-vaccine evangelical leaders.
