Hii Mounika!
Till now there's no such vaccine or medicine prepared for covid-19 pandemic. Researchers amd scientists and even doctors are trying their best all over the world to get some medication for the virus. But, no success has been reported officially till now. Human trials are also going on. Soon, we hope to get into some solution for it, having faith in our medical workers. Nothing is impossible, but it may take time.
Hope you understand.
Good luck!
