Atanas Mangarov, who is head of department at Sofia's specialist hospital for infectious diseases, will not be vaccinated, despite having seen the effects of the coronavirus himself.

- These vaccines are not well-manufactured, and in countries where many have been vaccinated, covid cases are among the vaccinated, he says.

The Bulgarian authorities oppose such allegations.

Iva Christova, head of Bulgaria's National Infection Control Institute, is frustrated.

- I can not understand how you as a researcher, or even as a doctor, can be against vaccines.

They have saved so many lives, she says.
