Just following up - checking around for relevant studies on this connection - most of the large scale studies I can find are assessing data in 2020 (e.g., Munro December 2020 is cited by many sources) when we were dealing with more dangerous variants. I hope there will be some more up to date accurate and reliable data available. It may be that the picture has changed somewhat.
On the tinnitus.org.uk website - a study cited (University of Manchester 31.7.2020) claimed that 6% of hospitalised cases developed tinnitus. Another study cited on the same website (MRHA 2022) found that the vaccine risk was 1 in 7000 overall which they rated at rare - this is based on the yellow card self reporting system - so we are assuming that all those who had the vaccine and subsequently got tinnitus - followed through and reported it.
So approx 1 in 20 hospitalised cases resulted in tinnitus.
And 1 in 7000 vaccinations resulted in tinnitus.
Even on the basis of these results - it is nowhere near 1000 times more likely to get tinnitus through COVID-19 infection compared with getting the vaccination. It is more like 300x IF we accept that mild COVID-19 cases result in the same % of tinnitus outcomes as hospitalised cases - something which is really probably very unlikely. Bear in mind - only a small percentage of overall covid19 confirmed infections end up in hospital.
Therefore the true figure could be way below 300x and could even be below 100x. Taking into account that the hospitalised cases are based on the Alpha and Delta variants - and the Omicron variants seem to be more transmissible but less dangerous - and the picture is far from clear. Therefore - I personally would not make any claims about whether there is more risk for tinnitus from taking the vaccine - or not. I would be neutral. And I have only presented this little study of the stats because the relative risk was brought up.
These risks could be useful to know - when someone with a good health profile and under 40 (for example) - is weighing up the relative risks. If you have a 1 in 2000 chance of being hospitalized from COVID-19 as an unvaccinated person (or had 2 vaccines and contemplating the booster) - and a further risk of just 1 in 20 of getting tinnitus - that would equate to an overall risk of 1 in 40,000 of getting tinnitus from COVID-19. Or take the vaccination and be subject to a 1 in 7000 risk.
I am not saying that I have a high level of confidence that any of my calculations are correct. I am moderately confident that my approximations are fair. But neither am I highly confident that declining the vaccination poses more risk of tinnitus than accepting it - based on my review of the stats - and it would vary depending on the individual.
I appreciate that there are other studies and I have used those from tinnitus.org.uk as they are a respected organisation providing - on a non-profit basis - the best possible information they can find for tinnitus sufferers.
