Covid-19 Vaccine and Diabetes: Can Diabetes Patient Take Covid Vaccine?

The Covid-19 crisis is an ongoing global concern that was declared a pandemic back on 11 March 2020. As of 2 July 2021, over 182 million cases have been confirmed across the world. Coronavirus is one of the most lethal pandemics in history that has ever hit humankind. The deaths due to the pandemic have mounted over 3.95 million. 

Covid-19 symptoms range from unnoticeable to life-threatening. The illness can be severe in elders who suffer from underlying medical conditions. Coronavirus transmits by breathing in contaminated air by droplets and airborne particles. Infected people remain contagious for nearly 20 days and can transmit the virus even without showing any symptoms. 

Covid-19 is caused by a virus known as the SARC-CoV-2 virus. This disease has no specific cure or treatment. The treatment, however, includes relieving symptoms, supplying oxygen, fluid therapy, and prone positioning as required. However, a safety measure in the case of coronavirus is vaccination. A coronavirus vaccine provides acquired immunity against the SARC-CoV-2 virus. The coronavirus vaccine is responsible for reducing the severity, spread, and deaths.

Covid-19 and Diabetes: Impact & Effects, Does COVID Affect Blood Sugar Levels?

The World Health Organization has declared coronavirus a health emergency of global concern. In severe cases, the coronavirus can cause kidney failure, infection in the lungs, and even death. Symptoms generally start in 3 to 7 days of being exposed to the virus. In some rare cases, symptoms might even take 14 days to appear. 

People of all varying age groups can be affected by the coronavirus, but around 80% of the cases are mild. People with underlying medical conditions like asthma, diabetes, and heart diseases appear to be more vulnerable to get severely affected by the coronavirus. If people with diabetes get infected by the coronavirus, it can get difficult to treat them. People with diabetes can have complications and fluctuations in blood sugar levels that interfere with treatments.

There are two possible reasons for this. First, the coronavirus might thrive in a body with high blood glucose levels. Second, the immune system of people with diabetes often makes it harder for the body to defend itself from the virus, leading to a long period of being sick. 

How Does the Covid-19 Vaccine Work?

How Does the Covid-19 Vaccine Work?

Different vaccines work differently to protect against coronavirus. But, what is familiar with all the vaccines is they provide the body with a supply of memory B-lymphocytes and T-lymphocytes. These memory cells remember to fight against the coronavirus in the future. It takes nearly a few weeks for the vaccine to produce B-lymphocyte and T-lymphocyte cells after vaccination. Therefore, a person might get infected with coronavirus after or before getting vaccinated as the vaccine might not have had sufficient time to provide a protective cover. Sometimes people suffer from post-vaccination symptoms as a part of building immunity. The post-vaccination symptoms are the typical signs of developing immunity. Some common symptoms include fever, body ache, etc. 

Some Coronavirus Vaccines require Double Shots

For complete vaccination, you need to take two coronavirus vaccine shots for some vaccines. 

  • Two Shots: – If you choose a coronavirus vaccine that requires double shots, you can be considered fully vaccinated fourteen days post the second shot. Vaccines that come with two shots include Moderna, Covishield, and Pfizer-BioNTech.

  • Single Shot: – If you choose a coronavirus vaccine that requires a single shot, you can be considered fully vaccinated fourteen days post the shot.
