Since December 2020, the application of the Covid-19 vaccine began in the world. Since then, millions of doses have been supplied that have helped prevent serious illness. In the end, it has positioned itself as the best strategy to offer protection during the current pandemic. Although the truth is that various reactions have also been identified when receiving the biological from any manufacturer. In fact, paresthesia is the most recent side effect to be recognized.

In this sense, it should be noted that never before had a project of this type been developed in such a short time. Usually the creation of a new vaccine requires up to 10 years for all that it implies. You must start from the preclinical stage and advance with the other phases until your authorization is obtained.
On the other hand, on this occasion everything took place in just under a year and it was thanks to the sum of various factors. First is the global emergency caused by this new infection. SARS-CoV-2 immediately spread from the city of Wuhan to the rest of the planet. Therefore, a solution was needed as soon as possible.
Similarly, it also helped that there were various previous investigations. The analysis of coronaviruses began several years before, so there was a reference. While another aspect to consider was the enormous amount of money that pharmaceutical companies allocated for each of their projects. In the end, everything served to obtain not only one but several options that are the ones that apply.
If anything has become clear, it is that all biologicals against Covid-19 offer good results. Although the effectiveness varies between each one, in the end they meet their objective, which is to generate antibodies to avoid serious illness. For the same reason, it is a strategy that has worked to prevent millions of deaths around the world.
On the other hand, it cannot be ignored that all vaccines, and not just those that have been manufactured against Covid-19, usually cause immediate discomfort. In the vast majority of cases, these are minor aspects that disappear in a short time. While so far very few serious cases have been reported compared to the billions of doses applied.
In this vein, paresthesia is now added as a new side effect recognized by health authorities. All part of the more recent report published by the Spanish Agency for Medicines and Health Products (AEMPS). The document indicates that this nuisance is associated with Moderna’s biological and therefore must be added to the label to inform the population.
And what does it consist of?
Based on the US National Institutes of Health (NIH) refers to a burning or prickling sensation that is usually felt in the hands, arms, legs, or feet, and sometimes in other parts of the body. In most cases it occurs without warning, it usually does not cause pain but is described as a tingling or numbness, like something walking on the skin or itchy.
Based on clinical trial information and global case reports, paraesthesia has been identified as a potential adverse reaction that may occur with rare frequency following administration of Spikevax. Similar adverse reactions have been previously described for this vaccine, such as hypoesthesia.
As of June 30, 2021, 1,425 cases of paresthesia had been identified as of the third day after vaccination with Spikevax, with more than 180 million doses administered worldwide.
In Spain, until January 9, 2022, 158 notifications of paresthesias have been registered after the administration of Spikevax. Until that date, about 14.2 million doses of this vaccine had been administered.
But although paresthesia is already a new side effect of the Moderna vaccine, the AEMPS adds that it is not dangerous. In fact, it is a transitory annoyance that disappears after a few hours. Therefore, there is no reason to withdraw the license for this immunization.
