Here you will find everything you need to know about how Pfizer-BioNTech works.

How effective is the Pfizer-BioNTech vaccine?

Phase 3 studies showed that Pfizer-BioNTech’s BNT162b2 vaccine was 90 percent effective in preventing infection.

The phase 3 clinical trial involved 43,538 participants.

According to documents published by the US government’s Food and Drug Administration (FDA), the vaccine works similarly for people of all racial and ethnic groups.

The FDA’s opinion is independent of the statements made by the Pfizer-BioNTech team.

How long does it take for the vaccine to work?

It seems to work quickly.

The Pfizer-BioNTech vaccine begins to work approximately two weeks after the first dose, with indications of effectiveness at 10 days.

The vaccine is safe and effective, according to the FDA, which has stated that there are no serious safety concerns with the injection.

How about a second dose?

Most of the participants in the Pfizer-BioNTech trials received a second booster injection.

The second dose is essential for protection beyond the short term.

What does the second shot do?

It acts as a booster, activating the immune system to produce durable memory cells that stick around to protect against the virus in the future.

When does someone get the reinforcement?

In the trial, the gap between doses ranged from 19 to 42 days.

The trial only followed people for two months, so at this stage there is no firm data on how long a person who has been vaccinated will be protected.

When could Australians get the vaccine?

The government wants regulatory approval to be completed in January and implemented in March.

How many doses of vaccine will Australia get?

To start with, there will be 10 million doses of Pfizer-BioNTech available starting in early 2021.

That means one dose and one booster for 5 million people.

Other candidate vaccines are in advanced stages, which could bolster this number.

Who will get it first in Australia?

1. People at higher risk (elderly, people with certain health problems, aboriginals and islanders of the Torres Strait).

2. Individuals at increased risk of exposure (health and elderly care workers, group residential care workers and disabled care workers, those employed in correctional and detention facilities and meat processing plants).

3. People who work in emergency services, defense forces, public health personnel, personnel who manage quarantine facilities, and workers employed by the main infrastructure and public services companies.

If I am vaccinated, can I still transmit the virus?

The trial was not designed to test this theory.

What this could mean is that someone who has been vaccinated can still get the virus, but will be asymptomatic.

If that is the case, a vaccine will not stop the spread of the virus.

So are masks and social distancing still key?

Health officials have urged people not to relax, even once vaccines have become widespread.

These measures are likely to remain in effect until the critical health threat is removed.

Digital vaccine passports are likely to be essential for international travel.
