Covid vaccines have side effects but benefits outweigh risks: study | Lifestyle Health

New Delhi: Even though COVID-19 vaccines save lives, there are serious side effects, causing inflammation of the heart as well as other premature non-communicable diseases (NCDs), according to several post-vaccination reports.

However, new research now claims that reported adverse events are few. According to the WHO, over 850 million cases and over 6.6 million deaths from COVID have been reported worldwide.

Currently, the mortality rate has been reduced due to the reduced pathogenicity of new SARS-CoV-2 variants, but the main factor in the reduction in mortality rates is “the administration of more than 12.8 billion doses of vaccine in the world”.

According to a paper published in the open-access scientific journal MDPI, the scientific community needs to investigate the full spectrum of COVID-19 vaccine-induced complications so that the necessary safety measures can be taken and current vaccines can be redesigned to avoid or minimize their side effects.

“We describe serious adverse events in depth for premature metabolic, mental and neurological disorders; cardiovascular, kidney, and autoimmune diseases, and reproductive health issues detected after COVID-19 vaccinations and whether these are causal or accidental,” the researchers wrote.

In any case, “it has become clear that the benefits of vaccinations far outweigh the risks,” they added. However, pre-existing conditions in vaccinated individuals should be considered in the prevention and treatment of adverse events.

Diabetes and COVID-19 have a two-way relationship. In addition to causing new onset or worsening of pre-existing diabetes, diabetes and high blood sugar are linked to a poorer prognosis in COVID-19 patients.

However, despite the likelihood that severe hyperglycemia is extremely rare in those vaccinated against COVID-19, “it is essential that clinicians be aware of these side effects and anticipate severe hyperglycemia in people with post-vaccination symptoms such as as excessive urination, excessive thirst, vision problems and fatigue,” the team wrote.

In the setting of cardiovascular disease (CVD), as a causal relationship has not been demonstrated between COVID-19 vaccination and the onset of hypertension, and patients in hypertensive crisis rarely require hospitalization , COVID-19 vaccinations show substantial benefits over its risks.

“Regarding arrhythmia, although one case of paroxysmal ventricular arrhythmia was reported for the BNT162b2 vaccine, no causal association was found,” the researchers said.

Additionally, exposure to COVID-19 poses a significantly higher risk of developing an arrhythmia. The pattern of COVID-19 vaccine-related myocarditis, on the other hand, is comparable to that of other viral infections, with a higher prevalence in adolescents and young adult men.

Most notably, the risk of myocarditis and hospitalization in this group of vaccinated individuals is lower than in unvaccinated COVID-19 patients, the paper states.

Regarding neurological disorders, mass vaccinations have confirmed that the risks of contracting serious neurological complications are by far much lower for people vaccinated with COVID-19 vaccines than for people who test positive for COVID-19, he added.

NCDs, also called chronic diseases, are often long-lasting non-communicable diseases. Examples of NCDs include mental health issues, stroke, heart disease, cancer, diabetes, and chronic lung disease.
