The Importance of Vaccinations – familydoctor.org
Path to improved health
Everyone needs vaccines. They are recommended for infants, children, teenagers, and adults. There are widely accepted immunization schedules available. They list what vaccines are needed, and at what age they should be given. Most vaccines are given to children. It’s recommended they receive 12 different vaccines by their 6th birthday. Some of these come in a series of shots. Some vaccines are combined so they can be given together with fewer shots.
The American Academy of Family Physicians (AAFP) believes that immunization is essential to preventing the spread of contagious diseases. Vaccines are especially important for at-risk populations such as young children and older adults. The AAFP offers vaccination recommendations, immunization schedules, and information on disease-specific vaccines.
Being up to date on vaccines is especially important as children head back to school. During the 2021 school year, state-required vaccines among kindergarteners dropped from 95% to 94%. In the 2021-2022 year it fell again to 93%. Part of this was due to disruptions from the COVID-19 pandemic.
Is there anyone who can’t get vaccines?
Some people with certain immune system diseases should not receive some types of vaccines and should speak with their health care providers first. There is also a small number of people who don’t respond to a particular vaccine. Because these people can’t be vaccinated, it’s very important everyone else gets vaccinated. This helps preserve the “herd immunity” for the vast majority of people. This means that if most people are immune to a disease because of vaccinations, it will stop spreading.
Are there side effects to vaccines?
There can be side effects after you or your child get a vaccine. They are usually mild. They include redness or swelling at the injection site. Sometimes children develop a low-grade fever. These symptoms usually go away in a day or two. More serious side effects have been reported but are rare.
Typically, it takes years of development and testing before a vaccine is approved as safe and effective. However, in cases affecting a global, public health crisis or pandemic, it is possible to advance research, development, and production of a vaccine for emergency needs. Scientists and doctors at the U.S. Food and Drug Administration (FDA) study the research before approving a vaccine. They also inspect places where the vaccines are produced to make sure all rules are being followed. After the vaccine is released to the public, the FDA continues to monitor its use. It makes sure there are no safety issues.
The benefits of their use far outweigh any risks of side effects.
What would happen if we stopped vaccinating children and adults?
If we stopped vaccinating, the diseases would start coming back. Aside from smallpox, all other diseases are still active in some part of the world. If we don’t stay vaccinated, the diseases will come back. There would be epidemics, just like there used to be.
This happened in Japan in the 1970s. They had a good vaccination program for pertussis (whooping cough). Around 80% of Japanese children received a vaccination. In 1974, there were 393 cases of whooping cough and no deaths. Then rumors began that the vaccine was unsafe and wasn’t needed. By 1976, the vaccination rate was 10%. In 1979, there was a pertussis epidemic, with more than 13,000 cases and 41 deaths. Soon after, vaccination rates improved, and the number of cases went back down.
