Older age is a significant risk factor for serious illness and death for COVID-19. For the 23rd of January 97% of the deaths were people over 50; averaging out to 98% for the last 7 days.

Vaccine Efficacy Against Death Once Hospitalised for the 23rd of January, 2022 was calculated to be NEGATIVE at -64%.

The 7 day average was calculated to also be NEGATIVE at -84%.

About

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.

Disclaimer:

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. I will attempt to access all the required data but at this stage these —real world— numbers are what we have to work with.

Data:

Patients in hospital:

Vaxxed 70.2%
Unvaxxed 27.6%

*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.

Deaths:

Sadly, NSW Health is reporting the deaths of 34 people with COVID-19; 26 men and eight women.

Two people had received three doses of a COVID-19 vaccine, 23 people had received two doses, three people had received one dose and six people were not vaccinated.

Triple or Double Vaxxed 25 ppl (73.5%)
Partially Vaxxed 3 ppl (8.8%)
Unvaxxed 6 ppl (17.6%)

*Data taken from NSW Health twitter update with links to the tweets further down this page. Partially vaxxed were excluded from this calculation and were not added neither to the vaxxed or unvaxxed.

Calculation:

NOTE:

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).
