Many vaccines have been produced worldwide and the vaccine for 750 million people in the world may soon begin to be given a large scale. But the claims that have been made about the success rate of all these vaccines have consigned people.
There are currently more than 112 infectious diseases in the world that are spread by viruses, bacteria or parasites, and nearly 17 million people die each year. But in the last 200 years, only one of these diseases has been completely eradicated and that is small pox. This success was achieved in the year 1980. But there is no more contagious disease that has been eradicated from the root.
However, scientists around the world are trying to eradicate coronavirus from the root. But nothing can still be said about how and when it will happen because, usually, it takes 5 to 10 years to prepare a vaccine. But this is the only vaccine that has been produced in 10 months.
Big claims about success rate
Therefore, it is important to know what the far-reaching consequences will be. Well, many vaccines have been produced worldwide and the vaccine for 750 million people in the world may soon start in a big way. But the claims that have been made about the success rate of all these vaccines have consigned the people. As each model of smartphones sold in the market has different features, one’s processor is faster, one has more RAM. Similarly, all these vaccine features are different. But at the moment, the most debated is their success rate.
The rate may go down to 50 per cent.
Pfizer claims its vaccine is up to 95 percent effective. Moderna 94.5 percent. Russia’s Sputnik vaccine of 95 percent, Oxford and Astra-zeneca has been used to succeed up to 90 percent and Covaxin in India. But all these results have come from the third phase of trials and are the results achieved in a controlled environment. But when these vaccines are available to the common people, their success rate can go down to 50 per cent.
95% in trial but how many people will get vaccine in real life?
This is because during the trial, people are divided into two groups and out of these, the vaccine is given and half of the people are not given any vaccine. Pfizer’s trial involved 43,000 people, 170 of them infected with The Corona. But 162 of these people were not given any vaccine, while 8 people were vaccinated. On this basis, up to 95 per cent of the vaccine is said to be successful. But it’s efficacy of this vaccine, not Effectiveness. Efficacy means 95 per cent of people have been found to have the ability to recover during the trial. But in real life, the number of people who will heal it will be judged by its effectiveness.
Usually, people who are involved in trials are healthy, i.e., they don’t already have a disease. But when the vaccine is given to millions of people in the world, it will be known about its real impact. According to The Lancet Medical Journal, 95 percent of the world’s people already have a disease. So when the vaccine is given to people around the world, they will be able to find out what percentage of these vaccines are effective on different people and in different situations.
How will people get vaccine ?
Now, for a moment, suppose all these vaccines are very successful even among the common people. But the question is, how will these Vaccine people get and how much money do you have to spend?
Oxford Astrazenca has said that 300 crore doses of its vaccine will be ready by 2021 and will be available at the same price worldwide at around Rs 222.
A dose of Pfizer’s vaccine can be available for around Rs 1400. Moderna’s vaccine will be the most expensive, which can cost Rs 4,000 per dose, while for covaccines being made in India, the price can be up to Rs 100 only. A dose of Russia’s Sputnik V will be available for Rs 740.
Countries around the world have started the process of buying these different vaccines. The US has placed orders for the highest number of vaccines, the second is europe’s country and the third is India. But still, all countries will be able to give vaccines to only 20 to 25 per cent of the people in the next one year.
In the first phase, these vaccines will be given to health workers, in the second phase, to social workers, to people above 65 years of age in the third phase and in the fourth phase.
Vaccines usually need to be stored at temperatures of 2 to 8 °C, it is not difficult for rich countries. But in poor and developing countries that lack resources and availability of electricity is a major problem, it can be difficult to store them.
India makes vaccines for the world, so people in India may not have so much problems getting these vaccines. About 300 crore vaccines are made in India every year. Out of these, 100 crore vaccines are exported.
Now, how will the vaccines be supplied from one corner of the world to another? Airplanes will be resorted to. According to an estimate, 8,000 jumbo jets will be required for this work. With the vaccine, these planes will land in different countries, then from there a refrigerated vehicle to the cold room. They will then be put in an ice box and transported to local health centers. The vaccine will be stored in these centres between 2 to 8 °C temperatures. They will then be transported in small ice boxes to vaccination camps.
The vaccine reached the right place at the right time. GPS trackers will also be installed on the boxes for this purpose.
Covid-19-like symptoms in people after vaccine
No vaccine is applied when it is infected, the vaccine is applied so that there is no infection. Now, because most vaccines are manufactured, either the weakened virus of the same disease is used or the vaccine is made from the dead virus.
Therefore, people may see symptoms like Covid-19 after they are taken to The Vaccine. May complain of high fever, muscle pain, lack of focus, and headaches. This is because the body’s immunity is identified and fought by the virus, and that is where immunity is created against the virus. The second dose of the vaccine will then be given to the people but the side effects will be minimal. But you may have to take a few days off from your work after vaccination.
There are often four kinds of vaccines that work against infection. The first is Genetic Vaccine. It contains genes of viruses that activate the immunity of the body.
The second is Viral Vector Vaccines, these vaccines enter the cells of the body, and the cells start producing virus-fighting proteins.
Then comes Protein-Based Vaccines containing proteins from corona virus.
The fourth is Inactivated Vaccines which are produced from weak or inactive viruses.
It can take up to 10 years for the vaccine to be researched, trialed and reached people for any major disease.
For example, it took 47 years for the polio vaccine to be ready. It took 42 years to make a vaccine against chicken pox and 43 years to prepare the Ebola vaccine. Hepatitis B took 13 years to prepare the vaccine and the biggest example is HIV AIDS. The first case of infection came in the year 1959. But even after 61 years have passed, the treatment has not been found.
PM Modi’s action plan to tackle corona epidemic
Prime Minister Narendra Modi held a meeting with chief ministers of different states on tackling the corona epidemic and vaccine preparedness. All you need to know. PM Modi says:
– Saving the lives of every countrymen is the priority of the government at this time.
-Corona Vaccine reaches everyone.
– The research work of Corona Vaccine in the country is in the final stages.
– Scientists will tell you when the vaccine will come and how many doses will be given.
– Vaccine will be given to people on priority basis.
– State governments should intensify their preparedness on vaccine maintenance and distribution.
The Prime Minister also said that the vaccination programme is long lasting, so there is a need to create task forces up to the state, district and block levels. The message of Narendra Modi’s meeting with chief ministers is clear that the government does not want to rush into corona vaccine.
