EU-approved Covid-19 vaccine protects against the dangerous delta variant
The COVID-19 vaccines approved in the EU offer protection against all coronavirus variants, as well as the delta variant as per Europe’s drug regulator. But they have called for vigilant tracking by vaccine manufacturers to stay alert.
As per Marco Cavaleri, European Medicines Agency’s (EMA) head of vaccine strategy, there have been several new variants and they expect more. He also believes it is crucial constant observation near monitoring all the approved vaccines’ performance against the variants emerging. 
Delta variant of SARS-CoV-2 which is very transmissible was first identified in India. It has led to new infections in different countries too.
Vaccine makers have exposed the blood of vaccinated people to viruses engineered to have the particular features of the variant of concern to assess if counterbalance antibodies get rid of that virus, to monitor probable new threats.
At present, four COVID-19 vaccines authorized by the European Union: vaccines from Pfizer and BioNTech, AstraZeneca and CureVac. However, the European Medicines Agency said they would evaluate the data of CureVac as the jab was only 48% effective in a final analysis according to the German BioTech firm.
EMA also confirmed that they have not received any authorization application for Covishield. As Covishield was excluded by the European Union as one of its approved vaccines, the tension between India and Europe rose recently.
