The coronavirus vaccination programme continues to be rolled out at pace, and increasing numbers of people are being invited to have their vaccine. We know that people with tinnitus have concerns about the impact of the vaccine and of Covid-19 on their condition, and we have put together some information to help you decide if vaccination is right for you.

Types of coronavirus vaccines

There are three vaccines being used in the UK at the moment. Both of these vaccines have been approved by the Medicines and Healthcare Products Regulatory Agency (MHRA).

Each vaccine is given in two doses, no longer than 12 weeks apart.

Pfizer/BioNTech vaccine

The results from the clinical trial showed the vaccine to be 95% effective at protecting people against developing Covid-19 after two doses[1], and suggested it is 52% effective in the period between doses.

Oxford University/AstraZeneca vaccine

The results from the latest study, where the two doses were given 12 weeks apart, show that this vaccine is 76% effective after three weeks, and 82% effective after the second dose.[2]

Moderna

Results from the clinical trial showed the vaccine to be 94% effective at protecting people against developing Covid-19 after two doses[3]. Moderna has only recently been introduced for use in the UK, so there is less information available via the Yellow Card Scheme.

Are the vaccines safe?

The MHRA is responsible for making sure that all medicines and medical devices – including vaccines – used in the UK are safe and effective. They have to approve any new treatment or vaccine before they can be used on the public in the UK.

Although the vaccines have been developed more quickly than normal, no stages of development and testing have been rushed or missed out. The speed has been due to international effort and collaboration in the face of the unprecedented threat from Covid-19.

The MHRA will also continue to monitor the vaccines over time.

The Yellow Card scheme

The Yellow Card scheme is the system for recording any suspected side effects from medicines, vaccines or medical devices. It is a vital part of helping the MHRA monitor the safety of all healthcare products in the UK.

Reports do not have to prove that a medicine, vaccine or medical device caused the side effect, there just has to be a suspicion that it may have.

Do the coronavirus vaccines cause tinnitus or make it worse?

In the trials prior to release, no mention was made of the onset of tinnitus or worsening tinnitus for either vaccine[4] [5].

The safety update report of 29 September 2021 from the MHRA estimates that 48.8 million first doses of the vaccines had been given, and around 44.8 million second doses[6].

A total of 370,574 Yellow Cards reporting adverse effects have been received[7].

A total of 5,915 reports of tinnitus were made.

This means that fewer than 1 in 8,250 people who have been vaccinated are affected which classifies this side effect as ‘rare’[8].

Does Covid-19 cause tinnitus or make tinnitus worse?

A study by audiologists at the University of Manchester found that a significant number of patients reported a deterioration in their hearing after hospitalisation for Covid-19, with 6.6% developing tinnitus.[9]

A global study found that 40% who had Covid-19 symptoms reported that their tinnitus was more bothersome.[10]

What should I do?

The evidence appears to show that both coronavirus vaccines are safe, and that any side effects are likely to be mild. The likelihood of the vaccines causing or making tinnitus worse appears to be very low.

The MHRA state that:

‘The expected benefits of the vaccines in preventing Covid-19 and serious complications associated with Covid-19 far outweigh any currently known side effects.’[11]

However, if you are concerned, please discuss your worries with your GP or with the medical professionals at the vaccination centre, as they will be able to advise you.

If you do experience any side effects, they can be reported using the Yellow Card scheme.[12]
