These days, the Coronavac vaccine of Sinovac, which is imported from China, has started to be given to health workers. With the introduction of the vaccine, questions began to emerge in each of our heads about the side effects, risk and efficacy of the vaccine.
Head of the Allergy and Asthma Association, Child Allergy Specialist Prof. Dr. Ahmet Akçay gave information about the side effects of the Coronavac vaccine and the risk of allergic reactions.
What is the Coronavac vaccine?
Coronavac vaccine is a dead vaccine inactivated with formaldehyde and used aluminum as an adjuvant. The virus is broken down and neutralized, stimulating our immunity without interruption to our body. It is thought to be safer because it is a dead vaccine.

Is It Effective?
According to the data of the study conducted in Brazil, 50.38% of the activity was reported. 91.25% and 65.3% according to Indonesian data were reported in the study conducted in Turkey. The vaccine has been reported to be 100% effective in protecting against serious and moderate infections. Although different results have been reported, it is thought that this vaccine, which has a minimum efficacy rate of 50%, will provide full efficacy in serious and fatal reactions. It is expected that much clearer information will be obtained by increasing the number of vaccines made with this data. How long the effectiveness of the vaccine will continue will be revealed according to the data of the vaccine results.

Does your vaccine have any allergy side effects?
According to phase 1 and II studies for coronavac vaccine, no significant allergic reactions have been reported. In only one case, urticaria (hives) was reported in the body 48 hours after vaccination, manifesting itself in the form of itchy, red plaques. In addition, the risk of allergic rash and allergic shock is rare, as is the case with any vaccine. Although there is no risky vaccine for drug allergies such as germany’s vaccine, there is still no risk of allergies. Adrenaline medication is available against allergy risk in vaccinated health institutions. As a result, the data obtained is a report of a small number of vaccine applications. Since the polyethylene glycol substance in biontec’s vaccine is not present in this vaccine, it can be said that the risk of developing allergies is less. There are no preservatives in the Chinese vaccine. The vaccine contains dysodium hydrogen phosphate, aluminum hydroxide, sodium dihydrogen phosphate, sodium chloride as an auxiliary substance. Those with a history of allergies to these substances should not be vaccinated.
Do you mind if the vaccine is given to people with allergic diseases?
This vaccine should be applied especially in risky groups. It is more beneficial to vaccinate those over 65, who have diabetes, who have heart disease. There is no harm in vaccinating those with allergic diseases such as asthma, allergic fever, eczema, food allergy. Only after vaccination, as with any vaccine, it is useful for them to wait under observation at the health institution for 30 minutes. In order to intervene urgently against the risks that may occur for those with allergic diseases, vaccination in hospital conditions will be beneficial against the risk of allergies. As the consequences of the side effects of vaccinations on health workers emerge, clearer recommendations will be made.
Can the vaccine be given to those with immunodeficiency?
- In patients with immunodeficiency, it is recommended to make the vaccine even if the vaccine creates a limited antibody response. In case of an immunodeficiency at the acute stage, treatment can finally be recommended. However, the patient needs to be well protected against coronaovirus. As the number of vaccines is increased, clearer information will emerge
Who Should Not Be Vaccinated?
- To people who are known to have any allergy to the components of the vaccine,
- Fever should not be given to those with acute disease and those in the acute initial stage of chronic disease.
Who should be careful?

What should be done if the vaccine has side effects?
Pain, swelling or redness in the vaccinated area; First of all, it is appropriate to raise your vaccinated arm. Instead of vaccination, you can apply towels soaked with cold water. Do not apply the ice directly. You can use painkillers containing paracetamol.
