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.
On June 20, 10.1 percent of the total samples tested had turned out Covid positive. Of the 9,409 beds reserved for coronavirus patients in Delhi hospitals, only 257 were occupied on Friday. Beds at Covid care centres and Covid health centres were lying vacant, the latest bulletin said.
There are 173 containment zones in the city at present, it added. Delhi has reported a few cases of the BA.4 and the BA.5 sub-variants of Omicron, which are highly transmissible, but experts have asked people not to panic as these sub-variants do not cause severe infection.The number of daily COVID-19 cases in Delhi had touched the record high of 28,867 on January 13 during the third wave of the pandemic. The city had recorded a positivity rate of 30.6 percent on January 14, the highest during the third wave of the pandemic.
