Two pioneering scientists who created the technology behind lifesaving Covid vaccines have won the Nobel Prize in medicine or physiology . Dr. Katalin Karik and Dr. Drew Weissman achieved their breakthrough by harnessing the power of genetic material known as messenger RNA or mRNA . Their discoveries have opened up a new chapter in medicine paving the way for new vaccines for other infectious diseases including the flu and treatments for noninfectious diseases such as cancer . Their breakthrough was in finding a way to alter the building blocks of RNA called nucleotides in order to make our bodies produce an immune response . The US hopes to have immunized million people against Covid by the end of February a top official said on December which is approximately percent of the country’s adult population. The push should start within weeks when vaccines developed by PfizerBioNTech and ModernaNIH are expected to be approved . The U.S. is expected to begin within weeks of the push should be approved within weeks . The vaccine is safe and strong protection against the Covid vaccine . The advent of mRNA vaccine has led to safe and . strong protection from Covid . proponents say this is just the beginning of this year . But proponents say it is just a safe and well-established technology is not just the start of the campaign . It has been described as ‘the beginning of the beginning’ of this season’. It is a safe vaccine”. It has also led to strong protection. The vaccine’ll be available for the U.Covid immunizations. It’�s immunizations, but it’ve been successful and effective. It will provide a long-established and effective and well established. A long-anticipated
