Question
Is the flu vaccine safe? I’ve heard there are many side effects, and I’m considering whether to have my child vaccinated.
Answer
Vaccines can have some side effects, but they are usually mild, such as pain, redness, or swelling at the injection site, or symptoms like fever, fatigue, and muscle aches. These side effects typically occur within 12 hours of vaccination and last for 1 to 2 days. While there have been reports of severe reactions, these are very rare. According to current statistics in China, the incidence of adverse reactions is between 1% and 10%, mostly regional reactions, with very rare abnormal or severe reactions. Before vaccination, parents need to sign an informed consent form to ensure they understand the potential risks and benefits of vaccination.
