New Zealand keeps curbs until next week to beat Delta; Auckland shut for longer

New Zealand had been largely virus-free, barring a small number of cases in February, but that changed last week after an outbreak of the Delta coronavirus variant erupted, prompting Prime Minister Jacinda Ardern to order a nationwide lockdown.

New Zealand on Friday extended pandemic restrictions by four days after which they will be eased slightly, although businesses and schools will remain shut and the biggest city Auckland will be locked down for longer.

The outbreak, which has so far infected nearly 350 people, may be reaching its peak, Ardern said at a news conference.

"We may be seeing the beginning of a plateau of cases," Ardern said. "But caution is still required."

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.
