Why vaccination is safe and important - NHS.
The belief that vaccines can cause autism has become widespread in the past few years. Parents seem to be most concerned about the MMR vaccine, which is used to prevent measles, mumps, and rubella.
No, there is no connection between vaccines and autism. Autism is a condition that affects the brain and makes communicating and interacting with other people more difficult. The cause(s) of autism is unknown. But genetics, differences in brain anatomy, and toxic substances in the environment are thought to contribute to children developing the condition. So how did the idea that vaccines play.
However, although health care professionals have much information about individual vaccines, they have much less information about the effects of administration of multiple vaccines at a single visit or the timing of the immunizations. Additionally, the cited concerns of health care professionals include efficacy of certain vaccines as well as appropriate delivery and communication regarding.
Immunizations, or vaccines as they're also known, safely and effectively use a small amount of a weakened or killed virus or bacteria or bits of lab-made protein that imitate the virus in order to.
Vaccines will involve some discomfort and may cause pain, redness, or tenderness at the site of injection but this is minimal compared to the pain, discomfort, and trauma of the diseases these vaccines prevent. Serious side effects following vaccination, such as severe allergic reaction, are very rare. The disease-prevention benefits of getting vaccines are much greater than the possible side.
But adults also need vaccines. Age alone increases the risk of potentially serious lung infections for more than 47 million Americans over the age of 65, because the body’s immune system naturally weakens with age. Vaccines work by teaching the body's immune system to recognize and defend against harmful viruses or bacteria before getting an infection, and reduce the chance of getting.
Vaccines are safe and effective. Because vaccines are given to millions of healthy people — including children — to prevent serious diseases, they’re held to very high safety standards. In this section, you’ll learn more about vaccine safety — and get answers to common questions about vaccine side effects. How are vaccines tested for safety?
