New Zealand to trial new Covid-19 vaccine

New Zealand has been chosen to be part of a late-stage trial for a new European Covid-19 vaccine.

The VLA2001 vaccine, created by French biotech company Valneva, has already been trialled on approximately 4000 volunteers in Europe.

The company is now looking for 300 adults across New Zealand.

The participants must be older than 56 and not have previously had Covid-19 or received a Covid-19 vaccine.

Director of Southern Clinical Trials Christchurch Dr. Simon Carson is the lead coordinating investigator for the New Zealand trial.

He says New Zealand's low case numbers and slower vaccine rollout is a large part of the reason for the trials being conducted here.

"The trial began in the UK but it requires people who a) haven't had Covid them self and b) haven't had a Covid vaccine and with the rapid rollout and with the state of Covid in the UK, they were basically running out of people, and pretty much the only place in the world to come to was New Zealand."

The New Zealand clinical trial is being managed by PharmaSols and will take place at eight Pacific Research Network sites across the country.

Carson says the VLA2001 vaccine is different from the Pfizer vaccine, in that it is a traditionally developed vaccine compared to some of the newer mRNA vaccines.

"It's thought that rather than just creating antibodies for the spike proteins, like the Pfizer one does, this may create a slightly larger range of antibodies and may give you more protection against other strains."

The vaccine is two doses, taken four weeks apart.

Participants will keep electronic diaries of any symptoms and undertake blood tests to monitor their antibodies.

He says the risks involved in participating in the trial are outlined in a patient information sheet.

"No vaccine is entirely safe, there is a range of side effects including local side effects such as a slightly sore arm, swelling and there are more generalised side effects such as raised temperature, feeling a bit off-colour for a few hours or slightly more.

"The side effects are looked at constantly through the trial and accessed by a safety committee and they appear to be no more than any other vaccine."

The company has been advertising the trial on several channels and Carson said it has received a good response so far.

"It's coinciding with the national rollout of the Pfizer vaccine so quite a few people have already had the Pfizer vaccine and people have contacted us saying 'Oh I would've come on this if I'd known about this slightly earlier', but with the timelines we've been given it is what it is."

He says he is excited to be a part of the global effort in fighting the virus.

"We continue to need new types of Covid vaccines, just the make sure population groups can access safe and effective vaccines. we're doing this not just for New Zealand but it's really a global endeavour if you like."

Vaccine Alliance Aotearoa New Zealand clinical evaluation director Dr Frances Priddy says she is supportive of the trial, and of increasing New Zealand's involvement in new Covid-19 vaccine studies.

"New Zealand needs to continue to contribute to the global effort to develop Covid-19 vaccines. This study gives New Zealanders an opportunity to be involved at a personal level. The participation of older adults is critical to help evaluate new vaccines for this population."

Valneva chief medical officer Juan Carlos Jaramillo adds, "The fight against Covid-19 continues and it's extremely important that we continue to gather as much data as possible in all age groups across the population.

"Everyone should have access to technology best suited to protect them against this virus. We have also been working on variants of concern as part of our continued efforts to stay ahead of the virus causing Covid-19 especially since we believe that our inactivated, whole-virus platform will be adaptable across variants.

"Hence we are extremely pleased to be able to invest in this very important additional clinical trial".

New Zealand is the only country outside of Europe where the VLA2001 vaccine is being trialled.

The UK government has already ordered 100 million doses of the vaccine. Production began at a factory in Scotland in January.

If all goes well the vaccine will be approved by regulators overseas and could be available in the UK by the end of the year.

You are right that the "old style" vaccines DO work, but the modern mRNA ones have not been given a fair crack yet. Personally, I’d rather have a serum that disables the critical part of the virus (mRNA), than have dead virus injected into me ("old style"), but I agree it is arguable. The only serious large scale studies that have been confirmed to date show 95% effectiveness for Pfizer. There are other results which are much lower, but these are not officially confirmed and may be due to other factors. Until we have 3 years of mRNA in the community, it will be impossible to draw a fair and sensible conclusion. All we can know at the moment is that vaccination ("old" or "new") is way better than not vaccinating.

So, choose a vaccine.

French or German? Having lived in both countries it’s a no-brainer for me... (Besides, I already had my first shot of Pfizer, so I don’t have the option. I am due for my second shot but I pushed it out by a month to give a 7 week gap, rather than 3. They were helpful, friendly, and efficient, and it was no problem.) You are FAR less likely to infect anybody else if you are vaccinated. (That’s leaving aside the personal protection you will get...) Try to imagine how you would feel if you were responsible for someone (maybe a family member or a child) getting infected and dying. It isn’t just about protecting ourselves; it is about protecting everybody. Whether you go French or German, it is still WAY better than remaining unvaccinated.

No Thanks

The French have been desperate to get in on this since the Pasteur Institute abandoned their Covid vaccine efforts.

I think we are starting to see the experimental Phizer vaccine unravel a bit with these new variants. The old tried and trusted methods, like with this vaccine and the Oxford AstraZeneca one, will prove to be the best and most effective. Seems to have worked a treat in the UK. People no longer need to isolate if positive. All totally normal. Track and trace? Lockdowns? Forget it.
