The ICMR (Indian Council for Medical Research) report on the sample of one of the two South Africa returnees, who tested COVID-19 positive with features "different from the Delta variant" of the virus is expected in the next two to three days, Karnataka Health Minister Dr K Sudhakar said on Tuesday.

He, however, said the two COVID infected people who arrived from South Africa here earlier this month were asymptomatic and did not require hospitalisation, but as a precautionary measure they were admitted to the hospital.

"The sample of one of the two infected persons is different from the delta variant. Hence, we had sent it to the Indian Council for Medical Research. It may take another two to three days to get the report," the Minister told reporters here.

Ahead of a meeting with officials here, amid growing concern over the Omicron variant, Sudhakar said he would discuss possible quarantine norms for those who come from abroad and test positive for COVID-19.

"Earlier we were allowing home quarantine for those who were asymptomatic but now we have to relook the norms following the discovery of new variant," Sudhakar said.

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.

He added that the Technical Advisory Committee has recommended a set of guidelines to the government, which will be discussed in the meeting and its outcome would be presented to Chief Minister Basavaraj Bommai to take a final call.

The minister clarified that there is no proposal before the government for imposing any restriction that could hinder the academic and economic activities in the state.

According to the health department officials, the two COVID infected persons had come to Bengaluru from South Africa on November 11 and November 20.

While the lab report confirmed that one of them was infected with Delta variant, the sample of the second person, who is a 63-year-old man, had features that is "different from the Delta variant".
