South Africa extended tight COVID-19 rules on Sunday for another 14 days, maintaining restrictions that include a ban on gatherings, a curfew from 9 p.m. to 4 a.m. and a prohibition on the sale of alcohol.

The country, the worst-hit on the African continent in terms of recorded cases and deaths, is in the grip of a third wave of infections driven by the more infectious Delta coronavirus variant.

"Our health system countrywide remains under pressure," President Cyril Ramaphosa said in a televised address to the nation.

Early this month South Africa recorded a new record of over 26,000 daily cases, stretching hospitals to breaking point.

Ramaphosa moved the country to the fourth level of a five-tier restriction scale in late June as infections climbed, promising to review the restrictions after two weeks.

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.
