As per the report Government of America has ordered 300 million doses of a hoped-for coronavirus medicine being developed by Oxford University and AstraZeneca and Department of Health and Human Services said on Thursday that everyone hopes that the first dose can be available by last October. It is good news for the world because the whole world is suffering from the Covid-19 and there is no vaccine available till now. So maybe it will work. The vaccine will may available by 2021 widely. AstraZeneca said that they are expecting to able to give a billion doses of a COVID-19 vaccine this year and in 2021 if tests are successful. The British medicine maker said that it had signed the first agreement at least 400 million doses of vaccine, which is developing by Oxford University. Only less of the vaccines in development advanced to human trials. As there is currently no vaccine available for coronavirus, but researchers and medicine makers are working on it. It could take a minimum of 18 months to develop. AstraZeneca also said one more thing that they received more than $1 billion from the U.S. Biomedical Advanced Research and Development Authority for the development and supply of the vaccine. And they also said that they planned to start to supply the vaccine in Britain by September. There are some more medicine makers who are trying to find vaccines of COVID-19 like Pfizer Inc, Johnson & Johnson, and Sanofi.
