The whole world is leaving no stone unturned to find the vaccine of Covid-19. In the race of inventing the vaccine of this virus, many less-known American and Chinese companies are coming forward to claim that they have made the vaccine and it is under trial now. The question which arises here is that how can we buy or use or implement the medicines of those companies which have no authenticity. According to Robin Shattock, an Imperial College London Professor “Is that protection against infection? Is it protection against severe disease?”
The first medicines of the world may come with some limitations and that may cure the infection but may harm us with something else. Mr. Shattock added, “It is quite possible, a vaccine that only protects against severe disease, would be very useful”.
In the new reports, it is said that now there are no symptoms on the Coronavirus patients, it is very hard to tell by the symptoms if the person is infected from the virus or not. The medicines, which are about to come in the market, claims that the symptoms of the disease will decrease and thus it will increase the number of patients.
Although, Vaccines are among the most effective weapons against infectious disease, according to a report of the World Health Organisation, vaccines prevent up to 3 million deaths every year. But still 3 percent of people who are treated by vaccine develop a mild form of the other disease and can spread it to others.
In their first attempt, developers are turning to technologies that have never been used in humans before. It’s a common approach to raise the level of antibodies is with the injection of a virus that has been inactivated or killed. This kind of vaccine by a Chinese laboratory is in progress. One more approach adopted by the University of Oxford uses an innovative approach in which COVID genes inserted into a different, harmless virus. According to the FDA spokesman Michael, he said, “We would potentially consider an indication related to prevention of severe disease, provided available data support the benefits of vacation”.
Having said she also added, “That is just practicality. And we may follow those up with more-perfect. There will never be a truly perfect vaccine”.
