need help with facebook ad targeting

Hello,

I'm trying to target people with interest in covid-19 and vaccinations.
please suggest what should I terget? any advice or input would be greatly appriciated

you could try the following:
International AIDS Vaccine Initiative
HIV Vaccine Trials Network
Pfizer
Vaccine-preventable diseases

That would be pretty much everyone right now. But if you don't already have an audience, you'll need to build one. Try from pageview campaign or something and then feed the audience in Lookalike audience campaigns.

You need to be careful when you are inputting words related to covid or some vaccines, as your ads may get disapproved as this is a very sensitive topic right now. But you can try to target people that are generally concerned about their health and that are trying to have a healthy life, this isn't that precise targeting, I know, but it's the safest one for that niche.

Try targeting the people that are interested in hospitals, pharmacy and basically anything related to medicine.

Good luck
