EU Agency Says Covid Vaccines Like Pfizer-BioNTech and Moderna ‘Promising’ Against Double variant

Coronavirus vaccines using mRNA technology like Pfizer-BioNTech and Moderna appear able to "neutralise" the variant of Covid-19 behind India's outbreak, the EU's drug watchdog said on Wednesday.

The EU has currently authorised four vaccines: mRNA vaccines Pfizer/BioNTech and Moderna, and the viral vector vaccines AstraZeneca and Johnson & Johnson. Viral vector vaccines like AstraZeneca and Johnson & Johnson use a genetically engineered version of a common cold causing adenovirus as a "vector" to shuttle genetic instructions into human cells.
