Karnataka Chief Minister BS Yediyurappa tested positive for coronavirus again on April 16. This is the second time when the 77-year-old Bharatiya Janata Party (BJP) veteran contracted the contagious infection since August last year.

"Karnataka CM BS Yediyurappa tests positive for COVID-19. He'll be shifted to Manipal hospital from Ramaiah Memorial hospital where he was admitted earlier today," the Chief Minister's Office (CMO) was quoted as saying by news agency ANI.

Yediyurappa had also tested positive for the virus on August 2, 2020. He was then diagnosed with mild symptoms, and had recovered after being briefly hospitalised.

On March 13, Yediyurappa, along with State Health Minister K Sudhakar, had received the first dose of anti-coronavirus vaccine.

The Karnataka CM being re-infected with COVID-19 comes amid a nationwide surge in coronavirus cases - with experts attributing it to mutations in the virus.

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 case also indicates that the new variants of coronavirus can skip through the immunity developed by the human body against the unmutated form of SARS-CoV-2019 virus.
