Igor Matovič, then still as prime minister, questioned the safety of the Vaxzevria Covid-19 vaccine back in February. Around the same time, the vaccine manufacturer AstraZeneca faced problems with deliveries to the European Union. Later in spring, Slovakia briefly suspended the use of the vaccine in the Covid vaccination rollout, following the death of a 47-year-old woman.

AstraZeneca's Cluster Country Director for Central Europe, Kuuno Vaher, describes in an interview with The Slovak Spectator how the company sees these cases and how the development of the next Covid-19 vaccine is progressing.
The Slovak Spectator (TSS): Are you vaccinated?
Kuuno Vaher (KV): Yes I'm vaccinated with Vaxzevria and all my colleagues are vaccinated, though AstraZeneca did not organise the vaccination of its employees. Our companies are producing vaccines, giving them to governments, and they organise vaccination. Our employees had to wait for their turn like everybody else and received the different vaccines which were available.
