New Delhi: Pfizer on Thursday claimed that its vaccine is highly effective against the Delta variant of coronavirus. Experts believe that the Delta variant, which has now emerged as a new concern for the entire world, was the moot reason behind the second wave of the pandemic in India. It is important to note that Pfizer is likely to strike a deal with the Indian government soon and its entry into the market will ramp up India’s fight against the Covid-19 pandemic. However, 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 Delta variants.Also Read - 11 Vital Tips to Keep Covid-19 at Bay This Monsoon
