As Delta variants has become the new cause for concern across the world, Pfizer says its vaccine is effective against Delta, first reported in India.

Pfizer which is in the final stages of striking an agreement with India claimed on Thursday that its vaccine is highly effective against the Delta variant of Covid-19, the variant which has emerged as a new threat to the world. In India, the Delta variant was considered to be the reason behind the second wave. A second mutation of the variant, called Delta Plus, has also been reported in India and in some other countries, including the UK and the US. Hence, all vaccine makers are relooking their data on the effectiveness of the vaccines on these variants.

As Pfizer seems all set to enter India, its effect against the Delta variant will amp up India’s fight against the Covid-19 pandemic. The union health ministry has said that both Covishield and Covaxin, the two vaccines which have been part of India’s vaccination drive, are effective against the Delta variant.

Sputnik V, the Russia-made vaccine available now in India, has also claimed that the vaccine is effective against the Delta variant.

Delta variant, first reported from India, has proved to have been more virulent than the previous variant. It is now responsible for around 100 per cent of Covid-19 infections in the UK.
