Clinical narrative: On March 24, 2021, I received the first dose of the Moderna vaccine against Covid-19. The next day, I present double vision when trying to focus at medium distance, it seems important to mention that this problem had never been presented before. On the third day of receiving the vaccine, I was hospitalized. At the hospital they performed different blood and imaging tests without finding a cause for my double vision problem, but I was diagnosed with paralysis of the cranial nerve VI of the right eye. Following, I describe in more detail day by day how I have felt after receiving the Moderna vaccine. My main interest in representing this report is to know if there are cases similar to mine, to know if there is information about whether this problem is temporary or permanent, if there is information about any treatment that can help me counteract the paralysis of the cranial nerve IV of the right eye and the most important, know if I should get the second dose of Moderna vaccine.   On March 24, 2021, I received the first dose of Moderna against Covid-19 intramuscularly in my left arm. Vaccine lot 003B21A at store pharmacy. The vaccine was given to me at approximately 4:19 p.m. After the application I returned home, had dinner and slept.   On March 25, 2021 at approximately 8 a.m. and while I was doing my normal activities, I realize that I see double objects that are at a medium distance. When discussing it with my relatives, they tell me that my left eye deviates towards my nose, which they had not observed before. I had this problem all day with no apparent change.   On the same day in the afternoon, I went to the pharmacy where they gave me the vaccine to ask if my double vision problem was among the side effects of the vaccine. The local pharmacist tells me no, but a report would be put up, and advised me go to the doctor if the vision problem does not disappear.   On March 26, 2021 I woke up with the same double vision problem. At 4 p.m. approximately, I went to the emergency services of the hospital. After asking me a couple of questions they referred me to the emergency service without doing any tests.   On March 27, 2021 and seeing that the problem did not improve I called the Moderna, Inc customer service number when not being attended by a person I left a voicemail describing my problem. and asking if my double vision problem is within the effects of the vaccine. A few hours later, I received a call from a representative of Moderna, Inc. Asking me to describe my vision problem and asked me a series of questions about where and when I received the vaccine, lot number, medications that I currently take among other. I agreed, and gave me a case number. Since then no one has contacted me. Asked me for my permission to contact me again, which I accepted, and gave me case number. Since then no one has contacted me.   Since my vision problem did not improve, I went to the emergency service of the hospital and where they performed several diagnostic tests including blood tests, electrocardiogram, x-rays, computed tomography, among others. The doctor told me that the blood studies were found in normal ranges and that the imaging tests did not report abnormalities. But he requested an MRI of the head to rule out a cerebrovascular problem or tumor. As a result of the above, I am transferred and hospitalized in the main building.   On March 28, 2021 at 8 a.m. I had blood tests done, and at 11 a.m. approximately I had an MRI of my head and nerves in the eyes. At 2 pm. approximately Dr. tells me that blood tests and imaging tests did not report abnormalities ruling out cerebrovascular diseases or tumors. She checks me again and she discharges me saying that I presented a problem in the cranial nerve IV of the right eye which should be checked by an ophthalmologist and she recommends eye clinic.   On March 29, 2021 I presented the problem of double vision, my relatives continue to observe that my eyes deviate when trying to focus.   On March 30, 2021 I presented the problem of double vision, my relatives continue to observe that my eyes deviate when trying to focus.   On March 31, 2021 at 9:20 a.m. I went to eye clinic where Dr. diagnosed me with  paralysis on the cranial nerves IV of the right eye and tells me that the problem should be resolved without intervention in a couple of weeks. Otherwise I must go to the neurologist and he refers me with Dr.   April 1, 2021 I presented the double vision problem.   April 2, 2021 I presented the double vision problem.   April 3, 2021 To this day I still presenting double vision.   Until this moment, I do not know if the damage is temporary or permanent, if there is any treatment to counteract the paralysis of the sixth cranial nerve of the right eye and most important, if I should apply the second dose of the Moderna vaccine against Covid-19. This last point seems to me of utmost importance since in different sources I have read that the side effects of the second dose are stronger than those experienced in the first dose.
