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.
Out of 14,288 people under institutional quarantine, 11,409 are lodged at 328 CCC-1 (COVID care centre) facilities, which have a collective capacity of over 50,000 beds, while 2,879 are kept at 57 CCC-2 facilities, having more than 6,100 beds, the BMC said.
The CCC-1 facilities are set up mostly in hotels and halls and do not have 24-hour monitoring facility, while CCC-2 are government facilities where doctors and nurses are available round-the-clock.
The BMC said it has acquired several hotels, guest houses, gymkhanas, halls and other places for institutional quarantine and isolation purposes.
It has sealed 6,552 buildings and declared 750 slums and chawls (small tenements) as containment zones, after one or more persons there tested positive for coronavirus.
Till Monday, Mumbai reported 85,326 COVID-19 cases and 4,935 deaths due to the disease, the BMC said.Follow our full coverage of the coronavirus pandemic here.
