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.
According to the health bulletin, authorities conducted 62,546 tests, including 45,525 RT-PCR ones, the previous day.
In April and May, Delhi battled a brutal second wave of the pandemic that claimed a massive number of lives and led to a shortage of oxygen at hospitals across the city.
On April 20, Delhi had reported 28,395 cases, the highest single-day rise in the city since the beginning of the pandemic. On April 22, the case positivity rate was 36.2 per cent, the highest so far.
The highest number of 448 deaths was reported on May 3.
The city government has been ramping up health infrastructure to prevent a repeat of the crisis witnessed during the peak of the second wave of coronavirus in April and May.
Steps have been taken to increase the number of hospital beds to accommodate up to 37,000 cases a day and to become self-reliant in terms of oxygen supply.
Around 7,000 ICU beds are also being added at government healthcare facilities in Shalimar Bagh, Kirari, Sarita Vihar, Sultanpuri, Raghuveer Nagar, and GTB Hospital and Chacha Nehru Hospital.
At present, there are 10,000 ICU beds in the capital.
Amid apprehensions of a third Covid wave in Delhi, experts suggested avoiding mass gatherings and celebrating the festivals in a scaled down manner, according to the minutes of a Delhi Disaster Management Authority meeting held last month.
At the meeting, Niti Aayog member Dr VK Paul emphasised that a narrative for celebrating festivals in a "simple manner" should be started as these events can easily reverse all the gains made in the fight against the Covid pandemic.
According to government data, 1.71 crore vaccine doses have been administered in the capital since the inoculation exercise started on January 16. Over 54 lakh people have received both the doses.Follow our full coverage of the coronavirus pandemic here.
