"There is no doubt in the effectiveness of the vaccines against the Delta variant of coronavirus, although this effectiveness has been reduced. There is no doubt in the reliability and effectiveness of the four vaccines approved for use in the EU and in Bulgaria against Covid-19," said Prof. Mariana Murdzheva, clinical immunologist and rector of MU-Plovdiv.

The best thing people who have received the first dose of AstraZeneca can do, is to continue and complete the immunization with the same vaccine. This will fulfill the vaccination process properly and in line with clinical trials which are made for this vaccine.

The AstraZeneca vaccine will not be administered to women under 60 with a higher risk of thrombosis. All individuals who have received a first dose of this vaccine and have not experienced side effects may be reimmunized with the same vaccine, said Minister of Health Prof. Kostadin Angelov, during a briefing, Novini.bg reported.

Epidemiological testing for Covid-19 is to take place in Bulgaria's second biggest city of Plovdiv. Around 1,000 people from the city are to be tested randomly, Prof. Dr. Mariana Murdzheva, Rector of the Medical University in Plovdiv said for the BNR.
