Know more about Diabetes, COVID-19 and  Vaccination


According to research, if people with diabetes have unsatisfactory control of their condition, such as high blood sugar, blood pressure, and cholesterol levels, obese, or suffer from complications such as heart disease, stroke, and kidney failure, he/she will have higher risk of developing serious complications during COVID-19 infection, such as using ventilator, receiving intensive care, or even death ¹.

Therefore, proper control of diabetes is extremely important to prevent complications or critical situations during disease progression. It is recommended that people with diabetes be vaccinated against influenza every year to prevent pneumonia and reduce the risk of heart disease and stroke caused by inflammation².Likewise, people with diabetes may benefit from being vaccinated against COVID-19 to reduce the risk of severe infection and damage to different organs in the body.

Professional Advice to Protect Your Health

In Hong Kong, more than 70% of deaths are caused by cancer, heart disease, stroke and pneumonia. Therefore, as many experts and officials have emphasized, the deaths that have occurred after vaccination with the COVID-19 vaccine are not directly related to vaccination.

When suffering from these diseases, many people are not diagnosed at early stage because there are no obvious symptoms, especially those with three-high risks of cardiovascular disease (i.e. high blood glucose, high blood pressure and high cholesterol).


According to a territory-wide survey from 2014 to 2015 ³, 1 in 12 adults in Hong Kong suffers from diabetes, and 1 in 3 adults suffers from obesity, high cholesterol or high blood pressure. Among them, half of them ignore their condition.


The COVID-19 pandemic and the serious consequences caused by the three-highs and diabetes have greatly reminded us of the importance of diabetes prevention. Early prevention can reduce the risk of heart disease, stroke, kidney failure and other complications and serious infections (including COVID-19)⁴.

Prevention is better than treatment – Get to Know your genetic risk for diabetes

Living with a high risk of emerging viral infections and chronic diseases, people with diabetes are a particularly vulnerable group. The risk of developing diabetes and its complications varies from person to person, in which genetics playing a key role. Although blood tests can diagnose the above conditions, they cannot rule out the possibility of future diseases.

Based on more than 20 years of clinical research and data analysis by local universities, GemVCare uses advanced patented technology and unique algorithms to help the general public assess the risk of developing diabetes or its complications in the future, so as to take early action to protect one’s health.
