Dr. János Szlávik acknowledged the impact of inoculating more than 2.5m Hungarians, so far, but said herd immunity would require 60-80% of the population to get the coronavirus vaccine.
He said the public's inclination to get inoculated wanes after some time, as seen in other countries, too, but that tendency could be countered with vaccination campaigns.
The expert also said the first doses of the single-jab Janssen COVID-19 vaccine would be available in Hungary from the coming week.
