How many time to come coronavirus vaccine
The world is continuously suffering due to the Coronavirus and everyone wants to know how many times to ready the coronavirus vaccine while the Director of NIAID says we would not have a vaccine that would even be ready to start to deploy for the year to a year and a half. That is the timeframe it seems like a long time. But if a vaccine for the coronavirus is ready by then it will be the fastest developed one in human history. However, the two Chinese leading pharmaceutical companies such as Moderna Therapeutics and Cansino Biologics started developing messenger RNA based vaccines which vaccines work differently from traditional ones. These vaccines target the proteins that allow viruses to spread and reproduce so, in the case of coronavirus scientists were able to extract a part of the genetic sequence and create a harmless version of it in the lab. This so-called spike protein antigen allows the virus to infect the human body cells and replicates, kill them off in the process. This evokes an immune response in the body that allows white blood cells to create specific antibodies to prevent the antigen from attaching to human cells and stopping the virus from spreading. While scientists at Moderna Therapeutics were able to create a trial MRAN vaccine quickly and the NIH (National Institute of Health) fast-tracked it to clinical trials in just days. And this has raised some eyebrows, as preventative vaccinations don’t cure diseases but rather prime immune systems to fight them off. This means they have to be tested on healthy people who run the risk of side effects that could potentially make them sicker than the viruses themselves. And as vaccinations could be deployed for millions even billions of people they have to pass more tests and protocols than most other medical treatments which is why they often take so long to get to market.
