COVID-19: drastic increase in incidence of severe vaccine reactions

In the USA, the Florida Health Department published new data on reported severe reactions as of February 2023. The numbers are surprising.

Study investigates why vaccine reactions increased

More vaccine reactions reported

Both physicians and patients in the USA can report possible vaccination reactions via VAERS. The data is then analysed and classified according to mild, moderate, or severe reactions. The latest figures are now available from Florida. The Department of Health reports that since the introduction of the mRNA vaccination against COVID-19, there has been a significant increase in the number of reported vaccination reactions - an increase of 1,700 percent.

Cardiac and cardiovascular complications are the most frequent

The number of life-threatening side effects is even greater: here the number increased by about 4,400 percent compared to the period before COVID vaccination. The data the Floridian authorities are observing is consistent with the findings of several studies.

For example, three different papers describe an increase in clotting disorders, cardiac arrests, cardiovascular events, thromboembolism, and general heart disease. The experts emphasise that such a development is new and unknown to this extent. It did not occur in this way during the vaccination wave for H1N1 infection in 2009.

Further studies needed to provide more clarity

Although the data are quite alarming, further studies are absolutely necessary to assess the short- and long-term consequences of COVID vaccination. In particular, the relationship between the vaccine and severe or even life-threatening cardiac complications should be further investigated. 

Conclusion for medical practice

Like any vaccination, the COVID-19 vaccine is not entirely free from side effects. This article is not a plea for or against vaccination. Rather, it is intended to highlight the possible adverse effects associated with vaccination, so that physicians can educate their patients and monitor them appropriately. Further studies will hopefully clarify in the future whether there is actually a connection between cardiac complications and the mRNA vaccine.
