In a major COVID-19 vaccination goof-up, an Uttar Pradesh resident was administered a different vaccine for his second dose. The man, a resident of Maharajganj district in UP, received Bharat Biotech's Covaxin as the first dose and the second one of AstraZeneca-Oxford University's Covishield.
The man lodged a complaint with the authorities upon realising the mistake made by hospital staff, Free Press Journal reported.
The complainant, along with two of his colleagues, got the first shot of Covaxin at the Maharajganj district hospital on February 25. The trio was scheduled to receive the second dose on March 25.
However, due to some work, they could not take the second shots and later went to take the second dose on April 13 at the same hospital.
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.
As per the report, the health worker, without checking the man's registration cards and other details, administered a shot of Covershield as the second dose instead of Covaxin.
Upon learning of the mix-up, his two colleagues refused to take the second shots and lodged a complaint with the Chief Minister's Office office.
Subsequently, the CMO Dr A.K. Srivastava did a medical check-up on the complainant and said there was no side-effect, the report said.
Meanwhile, the CMO has ordered the suspension of the health worker till the investigation is complete.
Earlier this month, a woman in UP's Kanpur was given two shots of the first dose by a nurse, who was busy on a call and forgot that the beneficiary was already given a shot. The nurse was suspended.Click here for Moneycontrol's full coverage of the COVID-19 outbreak
