Earlier, Tamil Nadu Chief Minister K Palaniswami had assured free immunisation against coronavirus for all sections of people in the state
Madhya Pradesh on October 22 became the second state to announce that a COVID-19 vaccine, whenever it is developed, would be made available free of cost to the people of the state.
The announcement came after Bharatiya Janata Party (BJP), in its poll manifesto for Bihar elections, said it would provide a free vaccine if it retains power, after which Tamil Nadu followed suit.
"The process for development of a vaccine n India is on at a rapid pace. Once a vaccine is ready, the vaccine will be made available free of cost to everyone in Madhya Pradesh," Chief Minister Shivraj Singh Chouhan tweeted, adding that the state administration has taken a number of steps to protect the people from the disease.
Frequently Asked Questions
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.
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.
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.
"Today it (the pandemic) is completely in control," Chouhan said.
Earlier, Tamil Nadu Chief Minister K Palaniswami had assured free immunisation against coronavirus for all sections of people in the state as soon as a vaccine is made available.
"I would like to announce that as soon as the vaccine is developed (and made available to states) all people in Tamil Nadu will be immunised and the government shall bear the cost," he said during an official visit.
Palaniswami's announcement had come hours after the BJP, in its poll manifesto, said a vaccine would be provided free of cost to the people of Bihar, prompting criticism from the Opposition.
Union Health Minister Harsh Vardhan has last week said India is expected to have a COVID-19 vaccine in a few months and the country should be in the process of delivering it to people in the next six months.At present, COVID-19 vaccines are in various stages of trials.
