Although medical experts believe that vaccination will be the most effective way to block COVID-19's group, many people are worried about the effects of the vaccine because they are not worried about the side effects of the vaccine.
According to foreign media reports, a recent study published by Israeli scientists on the medical preprint server pointed out that Pfizer / biontech vaccine does not have a substantial impact on sperm, but the new coronavirus often causes some neuropsychiatric symptoms.
In this study, 43 male volunteers who were vaccinated with Pfizer / biontech vaccine were invited to collect sperm before and one month after vaccination for analysis and comparison. It turns out that,After vaccination, the sperm parameters (including concentration, size, motility, etc.) did not change substantially.
The researchers said that although the study has yet to be peer-reviewed, it is good news for everyone, especially in the United States, where the birth rate has fallen to its lowest level in more than a century.
But in another study novel coronavirus pneumonia patients are prone to develop some neuropsychiatric symptoms. The study collected and analyzed data from 51 different studies, involving nearly 19000 patients. All patients were followed up for up to 6 months, and the follow-up action generally started 77 days after the diagnosis.
After analysis, it was found that,27.4% of the patients had sleep problems, 24.4% felt tired, and 20.2% had low scores in cognitive tests. In addition, 19.1% reported anxiety symptoms and 15.7% reported PTSD.
Neuropsychiatric symptoms caused by the new coronavirus are common, but neurotic episodes of dizziness / vertigo are uncommon, the researchers said. In the next step, longer follow-up will be needed to understand the duration of these symptoms and to determine whether the mental health-related symptoms are caused by common virus infection or coronavirus.
