What are the symptoms of an allergy to a flu vaccine?

Doctor's Answers 1

Hi there,

The signs of a severe allergic reaction can include difficulty breathing, hoarseness or wheezing, swelling around the eyes or lips, hives, paleness, weakness, a fast heart beat or dizziness.

Life threatening allergic reactions to the flu shot are rare. Moreveor, should there be one, these signs would most likely happen within a few minutes to a few hours after the vaccine is given.

Otherwise, receiving the flu vaccine is a fairly uncomplicated process. The common side effects that one might attribute to an allergic reaction include soreness, redness, swelling from the shot, headache, fever, nausea and muscle aches.

The Gardasil 9 vaccination provides protection against cervical cancer as well as warts. When a medication or injection is approved by the government, it relies on research to support the claims made by the medications. In this case, the claim is that: In the few thousands of patients that the company gave the vaccine to, these girls were between 9 to 26 years old. And according to the research, the injection did reach the outcomes that it claims. And hence, this is called the "label indication".
