Does United stated have already created corona virus vaccine ?

US pharmaceutical major Pfizer and its German partner BioNtech SE said on May 5 that they had already begun giving their coronavirus vaccine supplements to candidates for preliminary human trials in the United States. 

Trials have also started in Germany. On the other hand, Gilead Sciences has developed Remedsvir, a broad-spectrum antiviral drug that is being tested as a specific treatment for COVID-19 infection. 

The drug is authorized for emergency use in the USA and has also been approved for use in Japan for people with severe symptoms of coronavirus infection. Another pharmaceutical company, Regeneron, said its 'anti-body' treatment drug may also be available by September. 

Modern, Johnson & Johnson, and several other biopharmaceutical companies have also stepped up efforts to develop the COVID-19 vaccine. Johnson & Johnson is working with the Biomedical Advanced Research and Development Authority (BARDA). In March, the company announced that it had begun pre-clinical testing on several candidates in Boston and later revealed that it had selected its lead vaccine candidate, which had two back-ups. 

The country where the outbreak first occurred has said it has received positive results from animal trials of a potential COVID-19 vaccine. 

Beijing-based Synovac Biotech is in discussions with regulators in other countries, and the World Health Organization, to begin phase III clinical trials of the vaccine in areas where the novel coronavirus is still rapidly spreading.
