India has administered more than 82.86 lakh COVID-19 vaccine doses in the last 24 hours, taking the vaccination count beyond 121.94 crore, according to the Union Health Ministry update on November 28.
On the 315th day of the nationwide vaccination drive, over 25.75 lakh people received their first shot and 57.10 lakh their second dose.
The vaccination drive accelerated over the past few weeks. It took the country 85 days to give the first 10 crore doses, the next 10 crore took 45 days and, in another 29 days, India touched the 30-crore mark.
In the following 24 days, the count reached 40 crore and crossed the 50-crore mark after 20 days on August 6. By September 13, 75 crore vaccine doses were given. The biggest jump, however, came on September 17, when more than 2.1 crore shots were given in one day.
On October 21, India scripted history with cumulative COVID-19 vaccine doses administered in the country surpassing the 100-crore milestone.
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 government has revised the gap between the two doses for the Oxford-AstraZeneca’s Covishield, manufactured by the Serum Institute of India (SII), to 12-16 weeks. However, the interval for the second dose of Bharat Biotech’s Covaxin remains unchanged at four weeks.
Prime Minister Narendra Modi launched the nationwide vaccination drive on January 16, with healthcare workers at the frontline of India’s COVID-19 battle getting their first jabs. The next phase started on March 1 for people over 60 years and those aged 45 and above with specified comorbid conditions. From April 1, the drive was expanded to include all aged 45 and above. The government decided to expand the vaccination drive by allowing everyone above 18 to be vaccinated from May 1.
Some major developments related to COVID-19 vaccination:
- With new clusters emerging in Karnataka and threats of new variant 'Omicron' looming large, the state government on November 27 announced certain precautionary measures and said it has sought the Centre's permission to administer a booster dose of COVID-19 vaccine.
- Genomic variations and structural changes have been reported from other countries in the new variant of coronavirus but whether these alterations would impart increased transmissibility or make vaccines ineffective is under examination, senior ICMR scientist Samiran Panda said on the day.
- In Assam 2.10 crore people have received the first dose of the COVID-19 vaccines and the state government has decided to launch a week-long vaccination certificate drive from December 29, Chief Minister Himanta Biswa Sarma said on the day. The certification drive will cover all polling stations of the state and one lakh government employees will reach out to areas under more than 28,000 polling stations, Sarma said at a press conference in Guwahati. The three lakh people who are yet to receive the first jab will get it by next week, he said. More than 1.15 crore people have been fully vaccinated in the state so far, Sarma said.
- The new potentially highly-transmissible variant of COVID-19, named 'Omicron' by the WHO, is not a disaster as vaccines are still likely to protect against the serious disease from it, a UK scientist, who advises the government, said on the day.
