From 1st September 2023, all secondary school students in the UK are being offered Fluenz, a nasal spray vaccine for influenza.

Fluenz was formerly known as FluMist, which was found to be barely 3% effective in the 2016-17 flu season.

More worryingly, Fluenz currently has 311,999 adverse events reported on the WHO's official site.

This leads to many questions and the need for resources that I have listed below.

(the post is long so click on any question to jump to the relevant section)


Fluenz Tetra nasal spray is a vaccine designed to protect against influenza, commonly known as the flu.

Unlike traditional injections, this new style of vaccine is administered through a nasal spray. Fluenz Tetra contains weakened live flu viruses that are designed to stimulate the immune system to produce antibodies, in the hope of providing immunity against flu symptoms.



Just as if we were choosing a new car, it is worth considering the manufacturer's recent reputation.


First of all, what does the manufacturer AstraZeneca say?

¨...Like all medicines, this vaccine can cause side effects, although not everybody gets them. In clinical studies with the vaccine, most side effects were mild in nature and short-term...¨

This is the official AZ Fluenz side effect data presented on

Very common

(may affect more than 1 in 10 people):

  • runny or stuffy nose

  • reduced appetite

  • weakness


(may affect up to 1 in 10 people):

  • fever

  • muscle aches

  • headache


(may affect up to 1 in 100 people):

  • rash

  • nose bleed

  • allergic reactions

Very rare

(may affect up to 1 in 10,000 people):

  • severe allergic reaction: signs of a severe allergic reaction may include shortness of breath and swelling of the face or tongue.

They add ¨Tell your doctor straight away or seek urgent medical care if you experience any of the effects above.¨

They also add ¨You can also report side effects directly via the Yellow Card Scheme at or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.¨

This leads to three more key questions:

  • How did Astrazenca achieve the above statistics?

  • Are the statistics reliable?

  • How many reports of minor and serious side effects of Fluenz have been reported?

How did AstraZeneca achieve the above statistics?

The company performed safety trials

Are the statistics reliable?

The data from Fluenz studies have produced doubt in many.

Fluenz has been approved based partly on extremely short clinical trials using no placebo.

Serious scientists (and even Wikipedia) consider experiments without placebo and double-blinding as pseudo-science,

  • Trial PMC4796333 followed 385 participants for only 14 days

  • Trial PMC4181477 followed participants for 13 weeks. Amazingly the trial concluded:

¨Recipients of influenza vaccines had about 1.6 times more ILI episodes (Influenza Like Illness) than did unvaccinated children, and although this may be at least partly explained by a healthcare service-seeking bias, further investigations are warranted into whether influenza vaccine increases the risk of non-influenza ILI, as health-care-seeking behaviour did not predict ILI in a regression model...¨

That last paragraph is worth reading several times.

This study suggests that anyone worried about the flu and lets their children take the Fluenz vaccine, will see their children 1.6 times more likely to suffer the very influenza symptoms they were trying to avoid.

If the vaccine reduced the likelihood of flu symptoms by 1.6 times, I think it would be considered successful, so this appears to be having the wrong effect. Admittedly, the trial uses small numbers of participants making all the results not as reliable as we might hope for.

How many reports of minor and serious side effects of Fluenz have been reported?

We all know companies produce shining data to sell everything from broadband, to cars and computers. Who with a mobile phone trusts the manufacturer's claim of battery life? What car achieves the manufacturerś's fuel efficiency claims? And if anyone expects to achieve the broadband speeds advertised, I suggest monitoring them independently!

Let's take a look at the reported adverse events for Fluenz.


WHO's official site currently has 311,999 adverse events reported as of 20th September 2023 for Fluenz.

These include:

  • Facial Paralysis

  • Heart Inflammation

  • Pericarditis

  • Brain damage

  • Meningitis

  • Encephalitis

  • Guillain Barré

  • Streptococcus

This is a screenshot of the Fluenz adverse event data which you can access and check here


  • In late 2022, Fluenz was rolled out to all UK primary school children.

  • Just 4 weeks later, 19 children had died.

  • The deaths were blamed on Strep A.

  • However, Strep A is listed as one of the side effects of Fluenz.

  • The UK Government refuses to publish how many of these children took the nasal flu spray.



  • Genetically Modified Organisms (GMO)

  • Arginine hydrochloride (pituitary gland stimulator)

  • Dipotassium phosphate (can cause vomiting and diarrhoea)

  • Gelatin hydrolysate (ground up pigs bones )

These are the active strains in the 2023 concoction.

A/Darwin/9/2021 (H3N2) - like strain (A/Norway/16606/2021, MEDI 355293) / A/Victoria/2570/2019 (H1N1)pdm09 - like strain (A/Victoria/1/2020, MEDI 340505) / B/Austria/1359417/2021 - like strain (B/Austria/1359417/2021, MEDI 355292) / B/Phuket/3073/2013 - like strain (B/Phuket/3073/2013, MEDI 306444)

Manufactured using

  • Eggs

  • Chicken kidney cells

  • Pork gelatine

This is why the manufacturers say that anyone with an egg, pork or gelatine allergy should notify the vaccine team.

The schools are in a strange position where on one hand they are pushing the vaccine but on the other declining responsibility.

This is an excerpt from a recent school email to parents.

Dear Parent/Carer Please find below and email from the immunisation team. Please note that xxxxxxx school act as a host for the immunisations to take place however any questions you may have relating to consent need to be directed to the immunisation team and contact details can be found below: Dear Parent/Guardian, Your child's flu vaccination is now due. This vaccination is recommended to help protect your child against flu. Flu can be an unpleasant illness and can cause serious complications. Vaccinating your child will also help protect more vulnerable family and friends by preventing the spread of flu. Please complete the consent form using the following link: xxxxxx

Please ensure you complete your child's consent 48 working hours before your school session to ensure your child receives their vaccination. We are visiting your child's school on xxxxxxxxxxxx The vaccination is free and is a quick, simple and painless spray up the nose. Even if your child had the vaccine last year, the type of flu can vary each winter, so it is recommended to have it again this year or they won't be protected. A leaflet explaining the vaccination programme for secondary-aged young people can be accessed below and includes details about the small number of children for whom the nasal vaccine is not appropriate. The nasal spray vaccine contains a very small amount of purified porcine gelatine as an essential ingredient to keep it stable and able to work. For those who may not accept medicines or vaccines that contain porcine gelatine, a flu vaccine injection is available. Since the programme was introduced, most children offered the vaccine in schools have had the immunisation. Yours sincerely,



The title UK Health Security Agency infers gravitas for something once thought of so lightly that any kid with a sniffling nose was sent to school not to miss an important lesson.

This is from their website. Fascinating the way they mention infectious diseases next to germ and nuclear warfare.

The UK Health Security Agency (UKHSA) is responsible for protecting every member of every community from the impact of infectious diseases, chemical, biological, radiological and nuclear incidents and other health threats.

We provide intellectual, scientific and operational leadership at national and local level, as well as on the global stage, to make the nation’s health secure.

UKHSA is an executive agency, sponsored by the Department of Health and Social Care.

Is this a moment to remember how pre-2020 we teased Skivvers for having what we called man-flu? ;)

Here are screenshots of the school leaflet

The leaflet is glossy and persuasive.

Let me provide some alternative reasons to the last page.

1. Protect yourself.

The vaccine will help protect you against flu and serious complications such as bronchitis and pneumonia

- Research shows the vaccine makes the subjects 1.6X more likely to suffer flu symptoms The leaflet is glossy and persuasive.

- where is the evidence suggesting the vaccine protects against complications such as bronchitis and pneumonia?

2. Protect your family and friends.

Having the vaccine will help protect more vulnerable friends and family

- This is ignoring the established risk of shedding meaning the unvaccinated, and vulnerable are at risk from the live attenuated virus

3. No injection needed.

The nasal spray is painless and easy to have

- True enough

4. It’s better than having flu.

The nasal spray helps protect against flu, has been given to millions worldwide and has an excellent safety record

- The safety record can be seen here by looking at reported adverse reactions. Of course, this needs to be weighed against the total number of subjects, but we must also take into consideration the CDC and other official bodies admit only 1-10% of adverse reactions get reported. This means the injury data must be multiplied considerably by a factor of 1-100 to get a true idea of the risks

5. Avoid lost opportunities.

If you get flu, you may be unwell for several days and not be able to do the things you enjoy

- If you get the nasal spray studies indicate you are 1.6X more likely to get flu symptoms.

- If you are unvaccinated and in school for the days after the flu nasal mist has been used you are likely to suffer from shedding and to experience flu symptoms.


Shedding is a widely accepted and understood side effect of using live virus in vaccines.

When the vaccinated cough, sneeze, or detox via their breath or skin, they will pass the virus on.

It means that unvaccinated children, parents, and grandparents catch the live weakened virus from those who have been vaccinated.

i.e. the vaccinated spread the virus to the unvaccinated.

Many studies have set out to measure shedding

  • Study PMC6695509 seen on pubmed here, found that up to 67 % of vaccinated participants were shedding vaccine particles.


The standard has always been to take the children out of school on vaccination days and keep them out for at least 3 days.

Many now believe this should be 2 weeks.

Of course, this presents the issue of childcare for many.

I asked a well-informed mother what she had done in the past.

This was her reply.

¨...It all depends on risks to child or other family members.
When my friend´s father in law was undergoing chemo she pulled her two children out for a week.
I’ve removed xxxxxxxx for a week, 5 days, 3 days and last year just the vaccination day.
xxxxxxxx has never experienced shedding symptoms with the exception of last year, so in my book is deffo do 3 days off....¨

However, if we take a closer look at the above leaflet focusing on page 6, there is a more revealing clue.

It indeed looks like 2 weeks is the official 'unadmitted' expected window of shedding.

I imagine the risk from shedding moves in an exponential decline as in this graph.

So after three days, the risk will be significantly lower, and near negligible at 2 weeks.


  • Carry out your own research

  • Double-check the above data and information understanding some of it might be hard to find.

  • Be aware sites like Wikipedia and YouTube and search engines like Google are controlled by industry and agendas

  • As a starting point NEVER let your child (or anyone) have a vaccination when ill or off-colour. I have lost count of the parents who have told me their jab-injured child was not well on the day of the procedure.

  • If in doubt, wait. A child can always have the vaccination later if you so decide. Safer to Wait have an excellent website based on the concept

  • Remember to be kind to headmasters and teachers who are doing their best, but are limited by their knowledge.

  • Decline consent for your child to have the vaccine.

  • Use a template letter as seen below.

  • Take them out of school for the shedding period, requesting home-schooling lessons so they don´t fall behind.

  • Request that these days are not counted as absence,

  • Present uninformed teachers with key information.

  • Remind them attempting to use Gillick's competency could result in prosecution.

  • Inform other parents of the risks at your child's school so they can make informed choices.

We all want simple conflict-free lives.

Of course, it needs courage to stand against the flow of the majority.

My father often reminded me when in similar situations, such as being slower to cross a busy road than my friends...

¨It is better to appear a fool for a minute, than be one for a lifetime.¨
