Vertigo, dizziness and nausea after Covid vaccine

In general, vertigo, dizziness and lightheadedness are considered a rather common side effect following the Covid-19 vaccine. However, very often the onset of these events following the administration of the vaccine is not directly related to it.

In fact, according to the Centers for Disease Control and Prevention (CDC), many times dizziness after COVID-19 vaccination can occasionally be a symptom of an allergic reaction ( but this is most common in the first 15-30 minutes of vaccination) or an anxiety-related response, which often occurs after many different vaccines.

According to the aforementioned Covid-19 vaccine adverse reactions report, in UK out of 77.4 million doses administered the episodes of vertigo, dizziness and nausea related to the administration of the Covid 19 vaccine were:

Vaxzevria (Astrazeneca): 2164

Clogged ears and Covid vaccine

The sensation of a clogged ear can have numerous causes, including a plug of earwax, an otitis or the presence of water in the ear. This indicates that the sensation of muffled ear is very common, however at the moment no direct link with the administration of vaccine for Covid-19 has been reported or certified.

Can Covid-19 vaccine cause otitis?

As reported for plugged ears, otitis can also have several causes and it is common for this ear pathology to appear much more often in the summer, due to the water trapped in the ear which can lead to swimmer's ear. However, at the moment no direct link between otitis and the Covid-19 vaccine has been certified.
