Antibody levels after one shot given 6-8 months after infection, are at least as high as they are in people who have not previously been infected but received two shots. As a result the EU vaccine "passport" shows "fully vaccinated" for people who have been infected and have subsequently received one shot. That's the situation I'm in as are millions more Europeans. Will this be accepted as fully vaccinated by the US authorities? It'll be interesting
