What just happened?
According to Australia’s own drug regulator, the , the UK has provided an “emergency use” authorisation for the Pfizer vaccine, rather than going through the usual approval process. This emergency approval is temporary and is for a limited number of specific batches of the vaccine.
Meanwhile, the TGA says it continues to assess the safety and efficacy of the Pfizer vaccine as that information is submitted, and is working with regulators around the world to discuss vaccine development.
Hunt that despite the Pfizer news in the UK, Australia’s plans have not changed: “Our advice remains that the timeline for a decision on approval is expected by the end of January 2021, and our planning is for first vaccine delivery in March 2021.”
Why the wait?
One reason Australia might be able to afford to wait is that we are not facing the same acute public health emergency as the US, UK and some European countries.
The US is recording . Here in Australia, there have only been . There are currently hardly any cases of community transmission and since the end of October only has died.
There are also differences in how drug regulators around the world assess drug safety and efficacy.
In usual times, the TGA is in approving drugs than the FDA. However, most studies show that there have been with drugs fast-tracked by the FDA compared with drugs approved via its usual regulatory process.
The TGA is planning to use its which should speed up the process, but by how much is still a guess.
How fast is too fast? This is also unclear. The European Medicines Agency the UK’s quick emergency approval and said its own procedure relies on more evidence and checks.
There are many stages ahead
Regardless of the timing of regulatory approval, COVID vaccines still need to be made (and depending on the vaccine, imported), .
While all eyes are on the Pfizer vaccine at the moment, this is for which the Australian government has agreements in place, should they prove safe and effective. Some of these vaccines are still in clinical trials.
Australia has also signed up for a shot at several other vaccines as part of the World Health Organization-backed , should these prove safe and effective. Again, many of these are still in clinical trials.
Finally, people still need to be willing to be vaccinated. An of the Facebook page of the Australian Vaccination Risks Network, one of the country’s most prominent anti-vaccination groups, shows that since the start of the pandemic its page has attracted 36,962 likes and 32,350 comments; its posts have been shared 29,429 times.
In the meantime (and even for some time after vaccination), we will still need to wear masks when appropriate, physically distance and wash our hands. No vaccine will end the pandemic instantly.
So, should Australians be worried about the delay?
We don’t yet have long-term information about how long immunity will last and how common or serious any side-effects might be. There simply hasn’t been enough time. This might be less important in an emergency situation, but Australia is no longer in an emergency.
Many of us can’t wait to open up to the world and it’s hard to remain patient. But Melburnians, with their second lockdown, have taught us a lot about patience this year.
Perhaps we owe it to them to do our bit for the health of all Australians, accepting that time is a necessary part of good decision-making and planning.
And that involves waiting for a safe and effective vaccine to help us return to something resembling normal life.
