Emergence of Omicron was inevitable, says President Cyril Ramaphosa as cases increase five-fold in South Africa

The President said the number of daily infections has increased five-fold in the past week, with nearly a quarter of all COVID-19 tests now returning positive. Two weeks ago, only two per cent of tests were positive.

South Africa's fourth COVID-19 wave was anticipated and the emergence of the new Omicron variant was inevitable, President Cyril Ramaphosa has said, terming the surge in infections a matter of "great concern".

The President said the number of daily infections has increased five-fold in the past week, with nearly a quarter of all COVID-19 tests now returning positive. Two weeks ago, only two per cent of tests were positive.

"While the surge in infections is of great concern, we should remember that we anticipated it. Disease modellers in our country have told us that we would likely experience a fourth wave around this time and that it was almost inevitable that new variants of the virus would emerge," Ramaphosa said in his weekly newsletter to the nation on Monday.

"As the country heads into a fourth wave of COVID-19 infections, we are experiencing a rate of infections that we have not seen since the pandemic started. The Omicron variant that was brought to global attention by South African scientists nearly two weeks ago appears to be dominating new infections in most provinces," he said.

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.
