As countries around the world are competitively entering vaccination against the new coronavirus infection (Corona 19), as the initial supply dwindles, various measures are emerging. After the UK announced that it would increase the interval between primary and secondary vaccines and allow cross-vaccinations of different vaccines, the US began considering cutting the dose in half. This is to increase the number of vaccinations as soon as possible as the spread of Corona 19 accelerates due to the emergence of mutant viruses.

On the 3rd (local time), Executive Director Monsef Slawi, who leads the US vaccine program “Operation Super-Speed”, told CBS on the 3rd (local time) that “we are looking for ways to reduce the dose of moder or half vaccine. ” Slawi explained that “the Modena vaccines showed the same immune response as those who received 2 doses of 50 ㎍ (1 in 1 million g) twice in a clinical trial for adults aged 18 to 55 years.” did. “Having the dose in half is intended to provide immunity to more people,” he said, saying that he is discussing plans for a ‘half vaccine’ with the US Food and Drug Administration (FDA) and Modena. Implementation is dependent on FDA approval. In the United States, the number of confirmed cases has increased and decreased by 200,000 per day.

Expert opinions are mixed. Dr Natalie Dean, a vaccination expert at the University of Florida, told The New York Times that “half the vaccination is more scientific than delaying the second vaccination (as in the UK). It can be.” Chris Gildo, an infectious disease expert at Boston University, said: “Modern vaccines can be effective with a single dose. It is important to vaccinate more people as soon as possible.” On the other hand, Professor John Moore of Wail Cornell University said, “Since vaccines are already divided into very small doses, it can be difficult to cut some (inoculation doses) in half,” he said. “I don’t want to recommend ‘half the vaccine’ unless it’s unavoidable.

Meanwhile, India, a consignment producer of AstraZeneca-Oxford vaccines, announced its policy of not supplying the vaccines overseas until it meets its initial demand. Adar Funawala, Executive Director of the Serum Institute (SII) of India, in charge of the production of the shipment, said: “When the government gets approval for emergency use (last 2 days), there is a condition that the vaccine will not It will be exported for now so that the vaccine is secured first. There were, ”he explained. “The export will only take place after supplying the initial supply of 100 million lots (50 million people) to the Indian government over the next two months,” he said. The SII will manufacture 1 billion batches of AstraZeneca’s 3 billion batches this year to supply primarily to developing countries. Due to India’s “provide country first” policy, the AstraZeneca vaccine is expected to be difficult for the time being. In this regard, Jung Eun-kyung, head of the Central Defense Countermeasures Headquarters, explained in a briefing on the 4th that “the initial quantity of AstraZeneca entering Korea must be supplied with products produced by SK Bioscience (national)” .

On the 30th of last month, the first global vaccination of the vaccine was started in the UK, which approved the temporary use of a new vaccine against coronavirus infection (Corona 19) from AstraZeneca and the University of Oxford. Brian Finker, an 82-year-old man, first received the vaccine at Churchill Hospital in Oxford, according to the Associated Press.
