Can I get the COVID vaccine as I have a food allergy?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 48-year-old female. My height is 5'3, and my weight is 119.05 pounds. My symptoms are hives, itchiness, and sleeplessness. I used Zyrtec and Aquasoft moisturizing lotion.

After a mosquito bite, hives are formed, and now without mosquito bites, also have hives and itchiness. I started to have these symptoms for the last three weeks. After consuming Zyrtec, the symptoms stopped, and after two or three days, the symptoms reappeared.

Please help.

Hello,

Welcome to icliniq.com.

Hives can be triggered by a variety of insults. A detailed history and check-up will be needed to find out the exact cause of the same. Apart from mosquito bites, food, clothes, other insects, etc., can cause hives. Some medicines can also cause hives. If it is not subsiding in four weeks,

I suggest you undergo an expert evaluation. Till then, you can continue Zyrtec 10 mg one tablet for four weeks, then half a tablet for four weeks, alternate days, and stop. Avoid sudden stopping. Continue skin lotion also. You can also do CBC (complete blood count), ESR (erythrocyte sedimentation rate), AEC (absolute eosinophil count), Total IgE, TSH (thyroid-stimulating hormone), etc.

I hope this helps.

Thank you.

Patient's Query

Hello doctor,

I am going to take the vaccination. Since I have an allergy to mosquito bites and certain foods, is it safe? Now I am taking only half a tablet of Zyrtec once every three days.

But if I eat the forbidden foods, an allergy does appear, but it is only very mild, unlike earlier. Which one to take, Covaxin or Covishield? Will I develop any symptoms immediately following the vaccination shot? Please go through my attached medical summary.

Hi,

Welcome back to icliniq.com.

As of the latest guidelines, it is not advised to administer any COVID-19 vaccine to people suffering from prior drug allergies or food allergies. Since you have a history of food allergy, it is possible to get a reaction to the COVID-19 vaccine (rare possibility, still). This is just a possibility since you have multiple allergy triggers. We are concerned about the possible immediate severe allergic reaction like anaphylaxis.

Moreover, when you visit a vaccine booth, they will surely be asking if you have any allergy history so that they can cancel your vaccination schedule. So, it is better to continue with personal protective measures. I hope I am clear. If you have any doubt, you can message me back.

By the way, Covishield should be a better choice for anyone than Covaxin as per recommendations.

I hope this helps.

Thank you.

Patient's Query

Hi doctor,

I am not suffering from anaphylaxis, and I heard asthma patients have also gone through the vaccination shot and are doing fine. Is it true? I heard that allergy patients had consumed allergy drugs just before the shot and the next day also to avoid a reaction. Are these true?

Hi,

Welcome back to icliniq.com.

I know you are not having any anaphylaxis. But unfortunately, this is the current instruction received by the vaccinators. Asthma patients can receive the COVID-19 vaccine. No contraindication. They can receive. However, food allergy and drug allergies are not indicated. In my personal opinion, if you are getting vaccinated in a hospital setup, you may receive the vaccine if the concerned doctor in charge is willing to accept the risk.

This is my personal view. But usually, the concerned medical officer will follow the government guidelines only. Even if you take allergy tablets, anaphylaxis can occur in a severe allergic response. But simple itching and hives can be prevented. I hope it is clear. You can further contact your concerned medical officer to know what procedure they are following.

I hope this helps.

Thank you.
