How soon can the corona vaccine be available to the common people? – The latest updates on the vaccine
It has been around eight months since coronavirus hit the world was hit by the coronavirus. And so far, over two crore people have been infected with the deadly coronavirus and more than seven lakh people have died.
According to the World Health Organization, the first confirmed case of coronavirus was on 31 December 2019. Considering the speed with which the virus spread, WHO declared a Public Health Emergency on 30 January 2020. The infectious and highly contagious nature of this disease is what’s causing the rush on making a vaccine.
It is suspected that a large portion of the world’s population is affected by the coronavirus. And the situation can only get better if there was a corona vaccine available. The vaccine will not end the epidemic in just one stroke, but it can help people lead a more normal life, where lockdown is not necessary.
How is a vaccine made?
Human blood contains white blood cells in the blood which are part of its immune system. Without harming the body, a very small amount of viruses or bacteria are injected into the body through the vaccine. When the body’s defense system recognizes this virus or bacteria, the body learns to fight it.
After this, if a person encounters that virus or bacteria, then their body knows how to deal with the infection. Many doctors are using the original genetic code of this virus, which once they enter the body, makes viral proteins so that the body can learn to fight the virus.
How much progress has been made so far in making the vaccine?
Amidst all this, on August 11 Russian President Vladimir Putin announced that his scientists have prepared a vaccine that is effective against the coronavirus. Putin said that this vaccine has been tested on humans for two months and has met all safety standards. The Health Ministry of Russia has also approved this vaccine.
In May, World Health Organization Chief Scientist Soumya Viswanathan called Oxford’s project as the most advanced COVID vaccine. The first and second phases of the trial completed in England in April. It is now in the third and final phase which is being conducted in several countries around the world.
If the final stage results are also positive, the research team at Oxford University will apply by the end of the year for registration. The UK’s regulatory body Medicines and Healthcare Products Regulatory Agency (MHRA) by the end of the year.
The corona vaccine project that China’s private pharma company Sinovac Biotech is working on has reached the third and final phase of the trial. The vaccine has to be tested on humans to get approval from the government.
American pharma company ‘Fishers’ and German company ‘BioNtech’ are working together on a COVID vaccine project BNT162b2. The two companies have issued a joint statement that the vaccine project has reached the final stage of human testing. If these tests are successful, then by the end of October, they will be able to apply for government approval. The company plans to ensure 100 million vaccine supplies by the end of 2020 and 1.3 billion doses by the end of 2021.
It takes years or decades to develop a vaccine for any disease. But researchers around the world hope that they can do the same work in a few months to develop a corona vaccine . Many experts think that by the middle of 2021, the vaccine will become available for the public.
After the vaccine is ready, the first task will be to find out how safe it is. If it causes more problems than the disease, then the vaccine will not be of any benefit. And even after the vaccine is ready, billions of doses have to be prepared and made available to everyone around the world.
It is also speculated that the vaccine might have less effect on older people because as the age increases, the immunity of a person also decreases.
But until the vaccine is made, prevention is the best cure for Covid-19. The most effective way to prevent the coronavirus is wearing masks when outside. Washing your hands frequently and complying with the social distancing norms.
