Post-vaccine SARS-CoV-2 neurological complications are rare. However, due to the SARS-CoV-2 pandemic, massive vaccination has been carried out worldwide, which is why we have seen a greater report of post-vaccination neurological adverse effects.

We present 4 cases, which after receiving the SARS-CoV-2 vaccine presented 4 different neurological pathologies at the Hospital Comarcal de Vinaroz during the year 2021.

A relationship between vaccination and the onset of neurological symptoms is observed. Three patients presented clinical manifestations in relation to the BNT162b2 vaccine. The first patient after administration of the first dose of the BNT162b2 vaccine presented diplopia and palpebral ptosis, a condition compatible with ocular Myasthenia gravis. The second patient had symptoms of acute sensory motor axonal polyneuropathy after the third dose. The third patient, who after the third dose of BNT162b2 presented lethargic encephalopathy. The fourth patient presented symptoms compatible with aseptic meningitis after AZD1222 and mRNA-1273 vaccination.

Due to the worldwide mass vaccination campaign, reports of accidentally related or causally linked neurological complications are emerging. These are very varied; they could be related to immunological and/or toxic mechanisms. Physicians must be aware of these possible adverse effects and rule out other causes. Studies should be carried out that allow us to clarify the pathological mechanisms in relation to post-vaccination complications.
