Biomed summer program for am international Med student studying in a public college in Africa?

I am 1st year med student in a public university in an African country. Now I was wondering whether I would be able to do some kind of summer internship (biomed maybe or the such) abroad given that my school offers no chances and no exchange programs or the such (it is very poor in that department)

Can someone please give me any kind of advice?

Thanks!
