COVID-19 Vaccine Efficacy Against Death Once Hospitalised in NSW Australia — Monday 31 Jan, 2022

What’s your Reaction?


Older age is a significant risk factor for serious illness and death for COVID-19, particularly when combined with significant underlying health conditions.

Today’s data shows that 100% of the deaths were people over 60; averaging out to 99% for the last 7 days.

Vaccine Efficacy Against Death Once Hospitalised

Vaccine Efficacy Against Death Once Hospitalised for the 31st of January, 2022 was calculated to be NEGATIVE at -187%.

The 7 day moving average was calculated to be NEGATIVE at -38% (250 lives lost).

Hospitalised vs Mortality With Vaccine Status


Vaccine effectiveness against death once hospitalised simply looks at the latest known hospital occupancy of the vaxxed verses the unvaxxed and the deaths associated with the same cohort.

This calculation is measuring severe cases (hospitalised patients) and then comparing them against the final outcome and the number of deaths for this cohort. Vaccination rate of the population is irrelevant for this calculation as this method does NOT allow the vaccine to receive glory for vaxxing the young and healthy. This formula is a better measuring stick as it shows the true vaccine efficacy (protection) of the vulnerable (older age groups) once hospitalised.


We know that COVID-19 disproportionately targets the elderly and sadly the publicly available data provided by NSW Health is incomplete and we do not know the age breakdown of the people in hospital hence our limitations to draw authoritative conclusions. Sometimes they mention a particular individual with all the details but this is not the standard for all. Therefore the vaccine efficacy once hospitalised against death as calculated here should be treated as a rough guide and should only be applied to the older vulnerable age groups (+50) as they are the ones that are dying and that this data is representing. I will attempt to access all the required data but at this stage these —real world— numbers are what we have to work with.


Patients in hospital:

Vaxxed 71.8%
Unvaxxed 25.8%
Other 2.4%

*Data taken from the COVID-19 Risk Management Dashboard put out by NSW Health on the 19th of January. Please see screenshot at the bottom of page with link to the original document.


Sadly, NSW Health is today reporting the deaths of 27 people with COVID-19; 17 men and 10 women.

Of the 27 people who died; five were in their 60s, six were in their 70s, 10 were in their 80s and six were in their 90s.

Eight people who died had received three doses of a COVID-19 vaccine, 16 people had received two doses and three people were not vaccinated.

Of the four people who died who were aged under 65, three were men and one was a woman. Three people had received two doses of a COVID-19 vaccine and one person was unvaccinated. All four people had significant underlying health conditions.

Triple Vaxxed 8 ppl (29.6%)
Double Vaxxed 16 ppl (59.3%)
Partially Vaxxed 0 ppl (0.0%)
Unvaxxed 3 ppl (11.1%)

*Data taken from NSW Health twitter update with links to the tweets further down this page. Partially vaccinated have been added to the vaccinated because they were either injured by the vaccine and could not take the second shot or it is a direct result of vaccinating during a pandemic which has its own risks for the first 10 days after each shot and is part of the risks attributed to mass vaccination of the whole population.

Deaths by Dose, Comorbidity And Age Breakdown

*We do not get a detailed list of vaccine status for each case and age group but we do get totals per age group and sometimes they give us the comorbidity details as well.

Please remember I currently do not have access to detail mortality data broken down by age and vaccine status so the signal reliability will be crude and perhaps should only be applied to get an indication how well the vaccine protect the vulnerable (elderly).
