Coronavirus pandemic | No visitors at Australian zoo, but animals train for when lockdown ends

Australia has largely avoided the high numbers of casualties which have beset other countries as the coronavirus officially called COVID-19 leaves a path of destruction around the world, with about 6,600 infections and 71 deaths.

There are no visitors at Australia's biggest zoo due to the coronavirus restrictions, but training and feeding times must keep to schedule, keepers say, particularly for animals that perform in live shows like sea lions and birds of prey.

"Animals don't seem to react differently, however, they would definitely notice that there are no crowds out here when we are doing training sessions on stage," said Danielle Fox, supervisor of marine mammals at Sydney's Taronga Zoo.

Australia has largely avoided the high numbers of casualties which have beset other countries as the coronavirus officially called COVID-19 leaves a path of destruction around the world, with about 6,600 infections and 71 deaths.

That has been put down to heavy restrictions on public movement including border closures, shuttering most businesses that rely on paying visitors - like zoos - with no end date given.

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.
