There are a number of pre-vaccines developed by different research methods, and they are used to reduce the number of deaths and infections, as well as to reduce the number of those hospitalized.
The world has also been informed that new vaccines have been successfully developed this week - vaccines that have been proven to have an effect on almost all types of coronavirus.

Three major companies
Currently, there are three companies that are leading the way in developing coronavirus prevention: Pfizer / BioNTech and Moderna and Oxford / AstraZeneca.
Pfizer and Moderna have the same process.
Before they are produced, a part of the virus is injected into the human body, which then causes the body to produce certain proteins that will protect the body from attack.
But the vaccine developed by Oxford University is different because it uses a harmless chemical to provide the protection the body needs.
It is approved for use in the UK and Europe.
What about new vaccines?
New pre-vaccines were also produced by the end of January.
Janssen and Novavax have released new vaccines, which will be tested before approval can be given.

What are other countries doing?
In addition to these, there are some popular pre-vaccines that some countries include.
However, their use is not approved in Europe or the United States.
There are Sinovac and CanSino and Sinopharm. They are all from China, and have signed agreements with other Asian and Latin American countries.
There are reports that one million people have already been vaccinated against Sinopharm in China.
There is also a Russian-produced Sputnik V at the Gamaleya Research Center which publishes the results of its experiments - and confirms that some of the people who were tested had protection against coronary heart disease.
