Some folks are worried about adverse reactions to flu shots and health organizations such as the Center for Disease Control and Prevention, commonly called the CDC attempt to belay these issues by stating that adverse reaction to flu shot vaccinations is infrequent. Common reactions to flu shots contain swelling, redness and soreness at the point of injection, body aches and low grade fever.

Reactions

The usual reactions to flu shots aren’t of significant concern; it’s the rare adverse reaction to flu shot vaccinations which make some people wary of taking one. Many researchers and doctors think that severe reactions to flu shots happen due to thimerosal, a preservative that’s 59% mercury. All flu shots include some thimerosal; even the ones that are preservative free include trace quantities.

Mercury is a neurotoxin, meaning it damages or destroys brain and nerve cells. Researchers believe they’ve established a connection between mercury and autism. It’s thought that an increase in autism over the past several years is a negative reaction to flu shot and other childhood vaccinations.

Good to know

Some researchers and physicians believe that an increase in Alzheimer’s is a negative reaction to flu shot vaccinations, again due to mercury and other metals which are employed in manufacturing. According to a doctor’s study, individuals who had five consecutive flu vaccines between the years 1970 and 1980 were ten times more likely to develop Alzheimer’s compared to those who had none, one or two. Since Alzheimer’s doesn’t grow immediately following a vaccination, researchers can’t show it is a negative reaction to flu shot ingredients.

The truth is the CDC claims that there is”no persuasive evidence” that mercury has caused any responses to flu shots apart from redness, swelling and soreness at the point of injection. Their view is these minor reactions to flu shots are the result of allergies in certain individuals, but that mercury in flu shots poses no threat to the general public and the benefits of the influenza vaccine outweigh any risks.

Conclusion

Still, the CDC does suggest that some individuals shouldn’t take the flu shot or the nasal spray vaccine. Anyone who’s allergic to chicken eggs may have adverse reaction to flu shot vaccinations, because chicken eggs are used to increase the flu viruses. The CDC advises that allergic reactions to flu shots will occur within the first hours after receiving the shot and might include rapid heartbeat, breathing problems, hoarseness, wheezing, hives, paleness, weakness or nausea. Any negative reaction to flu shot vaccinations should be reported to a doctor and he ought to file a Vaccine Adverse Event Reporting System form.
