fainting, muscle aches, fever deemed very mild by authorities.

Problems they deem mild include “soreness, redness, or swelling where the shot was given, fainting (mainly adolescents), headache, muscle aches, fever, and nausea. If these problems occur, they usually begin soon after the shot and last 1-2 days.”

The CDC also is reporting that, “life-threatening allergic reactions to vaccines are very rare. If they do occur, it is usually within a few minutes to a few hours after the shot is given.”

If you are having a severe reaction the CDC said you may experience “high fever or behavior changes, difficulty breathing, hoarseness or wheezing, swelling around the eyes or lips, hives, paleness, weakness, a fast heart beat or dizziness.”

The CDC recommends seeking medical attention immediately if you spot any of the above symptoms.

The CDC also urges you to, “ask your doctor, nurse, or health department to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS) form. Or you can file this report yourself through the VAERS Web site at www.vaers.hhs.gov . You may call 1-800-822-7967 to receive a copy of the VAERS form.”
