A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic (to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen), or therapeutic (to fight a disease that has already occurred, such as cancer). Some vaccines offer full sterilizing immunity, in which infection is prevented completely.

http://en.wikipedia.org/wiki/Mumps

Mumps is a "viral" disease caused by the mumps virus. Initial symptoms are non-specific and include fever, headache, malaise, muscle pain, and loss of appetite. These symptoms are usually followed by painful swelling of the parotid glands, called parotitis, which is the most common symptom of infection.

http://en.wikipedia.org/wiki/Measles

Measles is a highly contagious infectious disease caused by measles "virus". Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than 40 °C, cough, runny nose, and inflamed eyes.

In simpler language (could be inaccurate) vaccines educate the body about viruses (rather than bacteria) by exposing the immune system to the (RNA) virus code that fingerprints the virus (also see CRISPR Gene / DNA editing- TED Talk by Jennifer Doudna is good).

http://www.ted.com/talks/jennifer_doudna_how_crispr_lets_us_edit_our_dna

Viruses are usually constructed of a cellular envelope containing hostile RNA code that injects into it's target to reproduce.

An RNA chain is half a DNA chain (or ladder- the code are the rungs of the ladder- with the rails being Carbon chains) made up of the DNA alphabet ACGT (compare with the machine language alphabet of 01/ or the English alphabet of a-z)

DNA is essentially a duplicated (dual RNA) computer code that defines the cells of the body.

The immune systems of mammals are fairly similar as I understand- and is based on White Cells which kill bacteria and T-Cells that kill viruses. T-Cells include T-Helper Cells that detect the virus and trigger the immune system, T-Killer Cells that kill the virus, T-Suppressor Cells that turn down the immune system.

From looking at bacteria (procaryotic cells- no nucleus), human cells (eucaryotic cells- has a nucleus), viruses, etc you can start to understand how life might have developed over time.

Hopefully this is useful JBowyer.

Thank you Canem for the trouble you went through but what about "The current jabs, first two, now four I am assured will not stop me getting or of passing on Covid. It is claimed though that I will get it less severely though."
That was the real question that oppresses us daily and I am unaware of it ever even being asked but Martin Foley said after the jabs etc. That made me very surprised and still no questions?

I finally accessed that database today.
Found an article about Craig Kelly texting everyone, they're not happy.
http://www.sbs.com.au/news/why-craig-kelly-has-been-allowed-to-send-you-texts-about-covid-19-vaccines/

As it turns out Craig Kellys giving out false information.
http://uap-media.com.au/tga-full-report-of-covid-vaccine-adverse-events-and-deaths/
The link to his site gives out the following info:

Number of reports (cases): 46438
Number of cases with a single suspected medicine: 45778
Number of cases where death was a reported outcome: 448

So I checked again myself and finally got access
- I noticed the Moderna Spikevax listing has been removed.
The data I got was this:

Number of reports (cases): 52318
Number of cases with a single suspected medicine: 51556
Number of cases where death was a reported outcome: 485

44 PAGES OF OF DIFFERENT KINDS OF ADVERSE REACTIONS
http://apps.tga.gov.au/PROD/DAEN/daen-report.aspx

I saw another page of medical conditions from the CDC on a video once as well, if I come across the list of conditions again I'll share it.

- And where can I get some Ivermectin, Hydrochloriquine, Prednisone, Anti-virals etc.
Surely I don't have to go to the doctor and pretend I've got lice and worms...

Vaccines are no guarantee of full immunity and some vaccinated people will inevitably still be affected. That's what the term "efficacy" means.

However even AZ is more effective than the typical annual Flu vaccine and 80% or something is better than 100% of nothing.

That's why masks and social distancing will need to be used until the pandemic eases.

The crazy use of Ivermectin may be a handy way of Nature flushing some people out of the gene pool.

In answer to your questions JBowyer-

1. The Corona virus changes every four months or so through mutation- so the body can't recognize it- it also can change how poisonous it is- and how quickly it spreads. This relates to different strains such as the Delta and Lambda strains.

2. Apparently the vaccine will protect a vaccinated person for the four months from developing symptoms but they will still act as a carrier and a transmitter- I'm not sure of the mechanism here. Based on this a high percentage of vaccinated people probably keeps ICU cases lower and people actually dying- if the ICU gets overwhelmed then more people die- but the new strains moving across the world probably mean that the crisis will never end without much greater national border controls. The Lambda strain only hit Australia in July 2021 seemingly from South America- now we have the new Mu strain. In my view the state politicians can do more to seal the national borders but the conflict between the Labor State Government of Victoria and the Liberal Federal Government has undermined this. I blame the Labor Victorian Government. Of course the Federal Government often relies on state police for enforcement.

3. I'm not sure whether you will get Corona less severely with vaccination. There seems to be a balance between theory and statistics to quantify risks. Of course there are other secondary-order socio-political risks alongside the first-order Corona ones that can and are just as concerning. One day I saw the death figures- 12 people died, 1 was 30-40 years old, 1 was unknown, 10 were over 60, 8 were over 70, 3 were over 80- from memory.

With LRTI's pneumonia and death is a risk- older people have reduced lung capacity. Without a vaccine you treat the symptoms. Keep the patient warm, calm, bed rest, give oxygen, etc, etc.

I find the Spanish Flu of 1918 as a useful comparison.
