A novelty that has led many people to wonder how the Moderna vaccine worksas well as if there are any side effects and if there is a thrombosis risk.
After what happened with AstraZeneca and Johnson & Johnson, citizens want to know exactly what they will encounter if they are given the vaccine: below is all the information to answer these doubts.
Modern vaccine, 400,000 doses in Italy: how it works
The “COVID-19 Vaccine Modern”Is produced by Moderna Biotech, a US company: it uses the same principle as Pfizer, as it is a mRNA vaccine.
Slightly lower, however, the effectiveness of the Moderna vaccine compared to Pfizer: we are al 93,6%, starting 14 days after the administration of the second dose. The coverage, from the administration of the second vaccine, is at least 6 months.
As anticipated, as for Pfizer and AstraZeneca, one is required double inoculation, at a distance of at least 28 days one from the other; as explained by the Aifa leaflet, subjects with severe febrile illness or acute infection vaccination must be postponed (while there are no problems in case of mild febrile symptoms).
Also for the conservation of the Moderna vaccine there are similarities with Pfizer: this one, in fact, goes into the freezer for one temperature between -25 ° and -15 °.
Modern vaccine: there are side effects
For the side effects we are along the same lines as other mRNA vaccines. In detail, the leaflet tells us that for the vaccinations administered the most frequent adverse reactions are:
- pain at the injection site (usually in the upper arm muscle) in 92% of cases;
- fatigue in 70% of cases;
- headache: in 64.7% of cases;
- myalgia in 61.5% of cases;
- arthralgia in 46.4% of cases;
- chills in 45.4% of cases;
- nausea and vomiting in 23% of cases;
- axillary swelling in 19.8% of cases;
- fever in 155% of cases;
- redness in 10% of cases.
The side effects of the Moderna vaccine have usually been of mild intensity O moderate and they resolved in a few days; sobering is the fact that in most cases the incidence of some adverse reactions was higher in the younger age groups than in the elderly.
Modern vaccine: is there a risk of thrombosis?
Until now, the Moderna vaccine has been widely used in the United States (where it is produced). To understand if there is a thrombosis risk, therefore, we must look at the data communicated by the FDA (Food and Drugs Administration).
In detail, right on the day of the precautionary stop for the Johnson & Johnson vaccine due to 6 cases of rare thrombosis, the FDA explained that regarding the Pfizer and Moderna vaccines, for which over 180 million doses have been administered to date, no cases of rare thrombosis associated with thrombocytopenia have been recorded.
For the moment, therefore, for the Moderna vaccine it seems there are zero risk of thrombosis. In this regard, it seems that Moderna and Pfizer have rejected Johnson & Johnson’s request to join efforts for research on the risks of blood clots related to serum: according to the two companies, in fact, the vaccine is 100% safe and there is no reason to jeopardize their reputation. Instead, it seems that AstraZeneca has accepted this invitation.
