We view all three as highly effective in preventing serious disease, hospitalization and death from COVID including disease caused by the very contagious delta variant of the coronavirus , and we believe that their benefits outweigh their risks. Most of these incidents occurred in women under age Read more about side effects related to a rare blood clot. Most of these myocarditis events happened in teens and young adults, and the majority of the cases were mild and cleared up on their own.
Read more about side effects related to myocarditis. There are several reasons why the COVID vaccines were developed faster than other vaccines: The technologies used to develop the COVID vaccines have been in development for years to prepare for outbreaks of infectious viruses.
Governments gave money to vaccine developers in advance, so the companies had resources they needed. Social media enabled companies to reach out to and enroll study volunteers, and plenty of people wanted to help, so there were enough research participants to test the COVID vaccines. We live in a crowded, fast-moving world, and disease travels easily. The data are clear: failure to immunize a child comes with a much more formidable risk—leaving children vulnerable to contracting a potentially debilitating or lethal illness.
Some children are too sick or too young to receive inoculations, so they remain at risk. If those children or other unvaccinated kids come into contact with someone else who was not protected against certain microbes, that can set off a wave of disease such as the measles outbreak in the U. Maladies that have become uncommon, such as polio and measles, can also quickly reappear if we stop vaccinating against them, particularly when they are unintentionally imported across geographic borders.

Side effects The overwhelming medical evidence finds that most vaccine side effects among newborns and young children are mild—swelling, redness and a small, hard lump at the site of the injection—and typically pass within a couple of days. What's in a vaccine?
Why do vaccines cause any side effects? Is such a high number of shots dangerous? Do vaccines cause autism? Vaccines contain ingredients that cause the body to develop immunity. Vaccines also contain very small amounts of other ingredients.
All ingredients play necessary roles either in making the vaccine, or in ensuring that the final product is safe and effective. Babies may get some temporary immunity protection from mom during the last few weeks of pregnancy, but only for diseases to which mom is immune.
Breastfeeding may also protect your baby temporarily from minor infections, like colds. These antibodies do not last long, leaving your baby vulnerable to disease. Some vaccine-preventable diseases, like pertussis whooping cough and chickenpox, remain common in the United States. On the other hand, other diseases vaccines prevent are no longer common in this country because of vaccines.
However, if we stopped vaccinating, the few cases we have in the United States could very quickly become tens or hundreds of thousands of cases.
Even though many serious vaccine-preventable diseases are uncommon in the United States, some are common in other parts of the world. Even if your family does not travel internationally, you could come into contact with international travelers anywhere in your community.
Your child needs a chickenpox vaccine because chickenpox can actually be a serious disease. In many cases, children experience a mild case of chickenpox, but other children may have blisters that become infected.
Others may develop pneumonia. Before vaccine was available, about 50 children died every year from chickenpox, and about 1 in children who got chickenpox was hospitalized. Natural immunity occurs when your child is exposed to a disease and becomes infected. It is true that natural immunity usually results in better immunity than vaccination, but the risks are much greater. A natural chickenpox infection may result in pneumonia, whereas the vaccine might only cause a sore arm for a couple of days.
The protection antibodies you passed to your baby before birth will give him some early protection against whooping cough and flu. However, these antibodies will only give him short-term protection. It is very important for your baby to get vaccines on time so he can start building his own protection against these serious diseases.

CDC and FDA take many steps to make sure vaccines are very safe both before and after the public begins using the vaccine. Mild side effects are expected Like any medicine, vaccines can cause side effects such as a low-grade fever, or pain and redness at injection site.
Severe, long lasting side effects are extremely rare. This was the greatest number of cases reported in the U. Top of Page. Get Email Updates.
