COVID-19 Vaccine

In order to prevent the spread of the COVID-19 virus and to protect individuals against the disease, some measures should be taken. It is of great importance that vaccination is done correctly, especially in order to improve immunity against the virus.

Developed vaccines not only help increase immunity, but also help reduce the risk of individuals contracting the virus and transmitting the virus to patients.

What are the COVID-19 Vaccine Types?

COVID-19 vaccines are produced by several different methods. However, all vaccines aim to make individuals immune to this virus.

Inactivated vaccines stimulate the immune system to render the virus ineffective or weak. This type of vaccine obtained from dead viruses should be stored at 2-8°C. Since traditional methods are used in the development of these vaccines, the production time is longer and slower. The CoronaVac vaccine of the Sinovac company belongs to the inactivated vaccine class.

mRNA vaccines allow artificial mRNAs produced in laboratories to stimulate the immune system. mRNAs, which take part in protein synthesis, are then excreted from the body like normal molecules. Pfizer-BioNTech and Moderna vaccines fall into the mRNA class. The biggest disadvantage of these vaccines is that they need to be stored at very low temperatures.

Viral vector vaccines are produced with genetically modified adenoviruses. These types of vaccines also carry the RNA of the COVID-19 virus at a level that does not cause disease. After vaccination, it is aimed that individuals become immune to the disease with the immune response of the body. These vaccines, produced with modern technologies, are stored between 2°C and 8°C.

Which Vaccines are Used for COVID-19?

Phase III studies of vaccines developed to protect public health against the COVID-19 virus continue. However, some approved vaccines have started to be implemented in many countries of the world. Vaccines that are also applied and planned to be applied in Turkey are Pfizer-BioNTech and CoronaVac mRNA vaccines. It has been stated that the protection level of vaccines is between 90-95% on average.


Pfizer-BioNTech uses the genetic material of the virus in its vaccine. (Genetic code encoding the spine protein) As it is an mRNA vaccine, it aims to synthesize the COVID-19 virus protein in the cells of individuals. In this way, the immune system that recognizes the virus can produce antibodies against the virus. 2 doses are administered with an interval of 21 days.


The CoronaVac vaccine produced by the Chinese company Sinovac is also produced from dead viruses. The purpose of this vaccine is for the immune system to recognize the COVID-19 virus. After the administration of this vaccine, the immune system produces antibodies to protect against the COVID-19 virus. CoronaVac vaccine is administered as 2 doses 28 days apart.

Who are COVID-19 Vaccine Could be?

In our country, the COVID-19 vaccine is administered in 4 stages determined by the Ministry of Health. The order in which the vaccine will be administered to individuals is determined according to whether there is a high risk, age, occupation, and whether there is a chronic disease.

1. Stage

  • Employees in healthcare institutions and pharmacies
  • Elderly, disabled and people living in protection homes and those working in these institutions
  • Individuals over the age of 65

2. Stage

  • Employees working in priority sectors for the continuation of the service, such as the Ministry of Interior, Ministry of National Defense, Ministry of Justice, municipal police, private security, prisons, education sector, food sector and transportation sector.
  • Individuals between 50-64 years of age

3. Stage

  • Individuals aged 18-49 years with a chronic illness
  • Other individuals between the ages of 18-49

4. Stage

  • Individuals who miss the vaccination order

What are the Side Effects of the COVID-19 Vaccine?

Laboratory studies show that approved vaccines have no serious side effects. The side effects seen are generally mild. Some of the side effects that can be seen after vaccination applications are as follows:

  • Shivering
  • Tiredness
  • Muscle and joint pain
  • Headache
  • Fever
  • Pain, redness, or swelling at the injection site
  • Vomiting
  • Diarrhea

Side effects, especially those who have an allergic structure, affect more. For this reason, it is necessary to inform the individuals before the vaccination and to check them for allergenic substances in order to avoid serious allergic reactions.

How Long does the COVID-19 Vaccine Protect?

It is thought that the protection of COVID-19 vaccines is valid for a certain period of time. Individuals who have had the disease are at risk of contracting COVID-19 again, as their antibody levels drop over time. In this sense, there is a low probability that individuals can be reinfected even if they are vaccinated.

High immunity to the virus means less chance of contracting the disease. For this reason, vaccines are administered as 2 doses at regular intervals. Clinical studies are ongoing to clarify how long the protection period these vaccines provide.

Can those with COVID-19 Get Vaccinated?

Patients who already have COVID-19 are considered immune to this disease. However, it is not known exactly how long this immunity will last. People who survived the disease can become infected again. At the same time, the duration of this natural immunity varies from patient to patient. In this sense, individuals who have had the disease should also be vaccinated. Depending on the type of treatment received, it may be necessary for people who have had the disease 90 days to be vaccinated.

Can Children Get the COVID-19 Vaccine?

There is no application for children in the COVID-19 vaccine calendar of the Ministry of Health. Vaccination applications worldwide are made only to young people and adults over the age of 16.

Do You Have to Follow Social Distancing Rules After Could the COVID-19 Vaccine?

Attention should be paid to hygiene and distance rules. At the same time, the use of masks after vaccination is an extremely critical measure to minimize the risk of contamination or contamination.

Can Alcohol be Taken After Biontech Vaccine?

Although there is no study on alcohol consumption, it is recommended not to drink alcohol for a day before vaccination and especially for 7-14 days after vaccination.
