The Karnataka government on September 19 issued orders to restrict students of class 9 to 12 from visiting schools and pre-university colleges to meet their teachers, citing a rise in COVID-19 cases in the state, news agency ANI reported.

The students were allowed earlier by the state Education Department, as per the guidelines issued by the Centre on August 29. This was after a fall in the cases of infectious disease in the state.

As of September 19 evening, cumulatively 5.11 lakh COVID-19 positive cases have been confirmed in the state, which includes 7,922 deaths and 4,04,841 discharges.


On August 29, Centre had allowed students between classes 9 and 12 to visit schools outside containment zones under Unlock 4.0.

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.

The guidelines also allowed opening of higher education institutions for research scholars (PhD) and post-graduate students of technical and professional programmes requiring laboratory/experimental works.

The Ministry of Home Affairs (MHA) on August 29 issued new guidelines under Unlock 4.0 for opening up of more activities in areas outside containment zones, as a part of Unlock 4.0, which will come into effect from September 1.
