We need a NZ version of this

The Immunisation Coalition in Australia has an excellent data tool which gives you relative chances of catching Covid-19, dying from it and also the chance of getting myocarditis from the vaccine. It would be great to have such a tool in New Zealand.

You enter your age (54 for me), your vaccinated status (triple) and the level of community transmission (high) and it gives you simple clear data. Mine is:

• Chance of catching Covid-19 in next two months: 1 in 190 (1 in 69 if unvaccinated)
• Chance of dying from Covid-19 if I get it: 1 in 25,000 (1 in 2,900 if unvaccinated)
• Chance of getting myocarditis from the vaccine: 1 in 140,000 for first dose, 1 in 1,000,000 for further doses. Background chance of myocarditis generally is 1 in 23,000 over two months.
• Chance of dying of myocarditis from the vaccine: 1 in 85 million for first dose, 1 in 600 million for third dose. Background chance of dying from myocarditis generally is 1 in 880,000 over two months.

So if you are 54 years old and unvaccinated you have a 1 in 200,000 chance of getting Covid-19 and dying from it in the next two months. If you take the vaccine your chance of getting myocarditis and dying from it is around 1 in 66 million.

If someone is 20 years old and triple vaccinated, the stats are:

• Chance of catching Covid-19 in next two months: 1 in 66 (1 in 24 if unvaccinated)
• Chance of dying from Covid-19 if I get it: 1 in 440,000 (1 in 51,000 if unvaccinated)
• Chance of getting myocarditis from the vaccine: 1 in 59,000 for first dose, 1 in 17,000 for further doses. Background chance of myocarditis generally is 1 in 25,000 over two months.
• Chance of dying of myocarditis from the vaccine: 1 in 35 million for first dose, 1 in 10 million for further doses. Background chance of dying from myocarditis generally is 1 in 2.1 million over two months.

So if you are 20 years old and unvaccinated you have a 1 in 1.2 million chance of getting Covid-19 and dying from it. If you take the vaccine your chance of getting myocarditis and dying from it is around 1 in 4.4 million.
