Five Million Vaccinated in Hungary Within Weeks? The number of people vaccinated against the coronavirus could reach five million within a few weeks, the leading infectologist of Budapest’s South Pest Central Hospital said on Monday. János Szlávik told news channel M1 that six or seven million vaccinated will be necessary to achieve herd immunity in the country. “The aim is to have as many people vaccinated as possible,” he said. “I believe Hungary is making good progress and I trust that the demand for vaccination will not slow down in the next few weeks,” he added. Despite the favourable vaccination figures, there are still many elderly people who have not signed up for a shot, he said.
