Huh. The second most important thing will be whether the immunity that is developing after vaccination is protective or not. This will be known gradually.

 

Are side effects also possible?

 

possible. But the side effects of the vaccine are or are not happening, one has to wait for some time to see it. According to one study, antibodies made from corona are effective only for about five months. In such a situation, nothing can be said about how effective the vaccine will be, because there is a competition to make vaccines in the world. So we have to wait a long time to see its result.

 

What is the work of the vaccine?

 

According to Dr. Uma Kumar, there are many types of vaccines. It develops local immunity. It does not allow any infection to grow again in the body. If the corona vaccine controls 80% of infections, then it is successful, because 20% of the people will survive herd immunity.

For decades, only real viruses have been used in vaccines that have been made worldwide to combat the virus.

 

How many people have to be vaccinated?

 

To prevent Covid-19 infection, it is believed that 60 to 70 percent of people will need to be vaccinated.

 

How many years does it take to make a vaccine?

 

Any vaccine is created to eliminate any infectious disease. It usually takes about 5 to 10 years to make a vaccine. Despite this, there is no guarantee of its success.

 

To date, only one human infectious disease has been eliminated and that is smallpox. But it took almost 200 years.

 

Apart from this, vaccines have also been made for polio, tetanus, measles, scrofula, TB. They have also been successful to a large extent, but even today we are living with these diseases.

 

Doctor Uma says that if the vaccine is launched within a year and a half, then it cannot track its shortcomings in such a short time. Its impact will be seen later. Sometimes the side effects of the vaccine also cause neurological, paralysis-like problems.

It usually takes 5 to 10 years to manufacture a vaccine. But the good thing is that within a few months a large number of manufacturers and investors have come forward to make Corona's vaccine. They have also placed their crores of rupees at stake.

 

Russia has also launched the Sputnik-5 vaccine and from October it will also be started to be introduced to people across the country. China has also claimed to have made the vaccine, it is talking about putting its soldiers first.

 

But all the countries and health institutions of the world are questioning both these vaccines because these records have been made in time, which has not happened till date.

 

The vaccine, which is named in the WHO list, has trials in its third phase. Some of these companies say that they will complete the vaccine production by the end of this year. But the WHO says that the manufacture of the vaccine is only possible by June next year.

 

Who will be given the vaccine first?

 

Doctor Uma says that if the vaccine comes, it will be given first to the health workers and high-risk group. After this, 20% of the population will be engaged.

What are the countries of the world doing to buy vaccines?

 

All countries around the world are signing pacts with pharma companies to get the vaccine. Apart from this, different countries are also forming groups to make and buy vaccines.

 

The UK has tied up 100 million vaccine doses with six companies. At the same time, the US government has said to arrange 300 million vaccine doses by January next year. The CDC has also told the pharma companies the time to launch the vaccine by November 1.

 

How will the vaccine reach poor countries?

 

Not every country in the world has the same status regarding buying a vaccine. WHO's Assistant Director-General, Dr. Mariazela Simao, says that the challenge before us is that when this vaccine is made, it is available to all countries, not just those who pay more. We have to check Vaccine Nationalism.

 

The WHO is also working to create a vaccine task force. For this, it has started work with the epidemic prevention group CEPI. Besides, the vaccine is also in talks with the Alliance of Government and Organization (GAVI).

How will the vaccine be distributed worldwide?

 

Institutions like WHO, UNICEF, Doctors Without Borders will play an important role in this work. They have to create a cold chain for this worldwide. In which arrangements have to be made such as cooler trucks, solar fridges, so that the vaccine can be saved at the right temperature and can be transported easily anywhere. The vaccine is usually kept at a temperature of 2 to 8 ° C.
