Prime Minister Narendra Modi on April 20 in his address to the nation appealed the state governments to urge migrants not to leave cities. He said workers should remain where they are, as states will arrange for their vaccination wherever they are.
The Premier assured the migrants that the state governments are working to increase testing capacity of vaccine productions and distributions as well. He even said that Indian doctors have have gained expertise in treating COVID-19.
मेरा राज्य प्रशासन से आग्रह है कि वो श्रमिकों का भरोसा जगाए रखें, उनसे आग्रह करें कि वो जहां हैं, वहीं रहें।
राज्यों द्वारा दिया गया ये भरोसा उनकी बहुत मदद करेगा कि वो जिस शहर में हैं वहीं पर अगले कुछ दिनों में वैक्सीन भी लगेगी और उनका काम भी बंद नहीं होगा: PM @narendramodi
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
How many types of vaccines are there?
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
What does it take to develop a vaccine of this kind?
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
On the issue of vaccines availability PM Modi said that 12 crore vaccine doses have been administered in India and a large large section of our senior population has been vaccinated. He added that from May 1, those above the age of 18 years can be vaccinated.
He expressed condolences to all the families who lost their near and dear ones in the coronavirus pandemic.
On the issue of increasing oxygen demand, he said that all sectors, be it public or private, are working together to tackle to fulfil the demand. The Premier said that the authorities have ramped up the necessary arrangements to help the people in need. Apart from developing vaccines and their approval, the PM said that various efforts are on to increase bed capacity in hospitals.
He even praised the health workers for their dedication in fighting this global epidemic.
Speaking on the issues of lockdown, PM Modi said, "I urge the States to consider lockdowns only as the last option and focus creating on micro containment zones." The Premier even added that there will be no need for a lockdown if we follow Covid protocols and urged people not to leave their homes unless really necessary.
