Union Health Minister Harsh Vardhan on Friday said the COVID-19 vaccination drive will be extended in the coming days and asserted that there should not be any misconceptions about the two Indian vaccines being administered in in the country.

During the Question Hour in Lok Sabha, Vardhan said India has vaccinated 3.5 to 4 crore people so far and side effects of the vaccines has been recorded at 0.000432 percent.

"Every vaccine doesn't require universal immunisation and all these priority groups whom we are vaccinating today like healthcare staff first and then senior citizens and people aged between 45 and 59 years, it will be extended in the coming days – all these are based on experts' opinion.

"Not only Indian experts, but we have also consulted WHO guidelines regarding priority groups," he said.

Serum Institute's Covishield and Bharat Biotech's Covaxin have been currently approved for restricted emergency use in India.

Frequently Asked Questions

How does a vaccine work?

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.

How many types of vaccines are there?

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.

What does it take to develop a vaccine of this kind?

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.

Replying to a question by NCP MP Supriya Sule on whether the government is aiming at universal immunisation of COVID-19 vaccine, Vardhan said it is not scientifically necessary to administer the vaccine to each and every person in the country.

"Not each and every person in the world will be vaccinated. The prioritisation process is a dynamic process.

"The behaviour of the virus is also dynamic. All things are based on scientific facts, scrutiny and vision of the overall scientific and health community," he said.

The minister said under India's present universal immunization programme, free vaccines are provided against 12 vaccine-preventable diseases, including Diphtheria, Pertussis, Tetanus, Polio, Measles, Rubella, severe form of Childhood Tuberculosis, Hepatitis B and Meningitis, among others.

Replying to a question by Congress MP Ravneet Singh Bittu about the fear in people that the COVID-19 vaccine will harm them in the future, Vardhan asserted that taking vaccines is the way to get rid of vaccine-preventable diseases.

"We got victory over polio and chicken pox due to the vaccination," he said.

There are detailed pre-clinical and clinical trials, which get thoroughly studied by the experts before a vaccine gets the nod, the minister said, adding that "There should not be any misconception regarding the COVID-19 vaccines and the people should avail the facilities given by the government get themselves vaccinated."

Vardhan further noted that there is a well-defined group of experts called the National Expert Group on Vaccine Administration (NEGVAC)).

"What you are seeing today is the hard work of the people in the ministry and this group, which was set up by the prime minister in August.

"Since then, they have been working closely regarding all scientific developments related to this," he said.

The minister also pointed out that the Subject Expert Committee has cleared two Indian vaccines (Covishield and Covaxin) after examining data provided by these companies.

Data provided by two Indian companies was also examined by the World Health Organisation, he added.

Replying to questions on Thalassemia, Vardhan, "Not a single thalassemia patient was deprived of blood during the COVID-19 pandemic period," he noted and said blood is provided free of cost to these patients.

Thalassemia major and the severe form of Thalassemia Intermedia (TI) constitute the major burden of disease and both are commonly managed by regular lifelong blood transfusions and iron chelation.

These syndromes are caused by inheritance of abnormal (beta) thalassemia genes from both parents or abnormal beta - thalassemia gene from one parent and abnormal variant haemoglobin gene (HbE, HbD) from the other parent.

The minister said in the last one year, 75 medical colleges have been sanctioned by the government.

"A total of 30,000 Health and Wellness centres were opened under the Ayushman Bharat scheme in the last one year during the COVID-19 pandemic period," he said.

Vardhan also said during the last six years 24,000 new post graduate medical seats have been created.
