COVID: WHAT ARE THE SIDE EFFECTS OF THE VACCINE and HOW LONG DO THEY LAST? Let’s be clear
VACCINE SIDE EFFECTS AND DURATIONGoes on coronavirus vaccination in Italy at a fast pace thanks to the four vaccines currently in use: Pfizer, with 37 million doses delivered, AstraZeneca (10 million), Modern (5 million) e Janssen (almost 2 million).
In the latest report on pharmacovigilance, the Italian drug agency talks about 204 reports of adverse events per 100 thousand doses administered, regardless of the type of vaccine and the severity of the disorder.
But then, what exactly are the side effects of the vaccine?
The most common, as reported by the newspaper Corriere della Sera turn out to be temperature, tiredness, headache, joint muscle pain, pain at the injection site, chills e nausea: they are more frequent after the second dose of mRna vaccines e after the first dose of AstraZeneca. The latter vaccine is also related to i very rare cases of intracranial venous thrombosis (1 case per 100,000 first doses administered, no cases after the second dose), mainly in people with less than 60 years old. That is prompted the Ministry of Health to decide to do not use AstraZeneca in some age groups.
When symptoms occur? As for the mild-moderate and therefore non-serious events, which are 90% of the total, the reaction occurred in most cases, on the same day as the vaccination or at most the following day, only more rarely beyond the following 48 hours. After mRna vaccines, Pfizer e Modern , the most frequent reactions are temperature, arm pain, tiredness, weakness, chills e general malaise. The effects of viral vector vaccines such as AstraZeneca e Janssen.
The arm pain is not felt by everyone and it is also common to other non-COVID vaccines. It can develop a few hours after the injection and last up to a few hours or even days: this is due to theactivation of the immune system. The intensity of this activation can depend on various factors: age, sex, stress. The inflammation may go beyond the injection site arm and spread to other parts of the body, primarily causing a temperature increase, until fever and to widespread pains.
It usually occurs within two days of the vaccine, and disappears within 48 hours. All these reactions they are absolutely normal and should not cause concern.
In addition to these effects, however, we must also add suspicious deaths.
