COVID-19 Vaccine Efficacy Against Death Once Hospitalised in NSW Australia — 20 Jan, 2022

What’s your Reaction?


Vaccine Efficacy Against Death Once Hospitalised for the 20th of January, 2022 was POSITIVE at +21.4%. The 7 day average was calculated to be NEGATIVE -85%.


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).


We know that COVID-19 disproportionately targets the elderly and sadly the data publicly made available by NSW Health is incomplete and we are unable to do this for each age group. We get information of the totals with age group but not an exact breakdown of vaccine status for each deceased individual or age group. Sometimes they mention a particular individual in detail hence the vaccine efficacy once hospitalised against death is only a rough indicator and should only be applied to the older vulnerable age groups only. I will attempt access all the required data but at this stage these —real world— numbers is what we have to work with.


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.


Of the 25 people who died; 16 people had received at least two doses of a COVID-19 vaccine, one person had received one dose and eight were not vaccinated.

Double Vaxxed 16 ppl (64.0%)
Partially Vaxxed 1 ppl (4.9%)
Unvaxxed 8 ppl (32.0%)

*Data generally taken from NSW Health Daily update from twitter with links to the actual tweet a bit further down this page.


*Above data table shows the percentage of death by vaccination status and the percentage of hospital occupancy by vaccination status for the same period. Partially vaxxed excluded from this calculation.

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).
