Covid-19 Vaccine

Over the weekend, US government officials reported that vaccinations had accelerated significantly. As of Monday, the Center for Disease Control and Prevention said nearly 4.6 million shots had been dispensed in the US, after a slow and uneven start to the campaign, marked by confusion, logistical hurdles and a patchwork of approaches by state and local authorities, reports AP.

Britain, meanwhile, became the first nation to start using the COVID-19 vaccine developed by AstraZeneca and Oxford University, ramping up its nationwide inoculation campaign amid soaring infection rates blamed on the new variant. Britain’s vaccination programme began on December  8 with the shot developed by Pfizer and its German partner BioNTech.

On Sunday, India, the world’s second-most populous country, authorised its first two COVID-19 vaccines — the Oxford-AstraZeneca one and another developed by an Indian company. The move paves the way for a huge inoculation programme in the nation of 1.4 billion people.
