Health Minister Satyendar Jain on Saturday dismissed any possibility of imposing another lockdown in Delhi, saying it was not a solution to check the spread of the coronavirus that is again surging rapidly.
Jain said there was a logic behind the lockdown enforced earlier as nobody knew then how the virus propagates.
"It follows a 14-day cycle -- between a person catching the infection and recovering from it. Experts said the virus will die if a lockdown is imposed for 21 days," Jain told reporters.
"Authorities kept on extending the lockdown, but the virus did not die. I don''t think lockdown is a solution," he said.
There is "no possibility" of imposing another lockdown in the city, Jain said.
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.
The minister added that there were enough hospital beds available for coronavirus patients and it could be increased if the need arises.
Delhi reported over 1,500 coronavirus cases for the second day on the trot on Friday, while nine more people, highest in around two months, succumbed to the pathogen, the Health Department said.
The 1,534 new infections pushed the tally to 6,54,276, while over 6.36 lakh patients have recovered from the virus. This is the highest number of cases since December 16 when 1,547 people tested positive, according to official data.
