Vaccine Side Effects and Adverse Events. Vaccines for Adults. Vaccines for Teenagers. To test the concern that vaccinations might bring on autoimmune conditions such as multiple sclerosis in adults, a review evaluated nine common vaccines, including tetanus, human papillomavirus, and seasonal flu. It found that cases of MS did not rise as a result of widespread vaccine use.
With COVID, regulators have added several extra pairs of eyes to watch for adverse events and report them as quickly as possible. This monitoring primarily happens via the Vaccine Adverse Reporting System VAERS , where any individual or physician can fill out a form flagging potential side effects.
Scientists then evaluate whether any reported effects occur beyond what is generally expected in the population. Massive computer power is put to use for the second leg of the stool, the Vaccine Safety Datalink.
This program is a collaboration between the CDC and nine large healthcare providers, the majority of which are part of the Kaiser Permanente system. The Datalink program flagged the febrile seizures with the MMRV vaccine, information that was brought to the public within months, Klein says.
Other programs involve long-term care facilities and large insurers tasked with flagging issues emerging in their patient populations. Experts begin this robust monitoring process with a ready list of potential side effects. Also on this list: the blood clotting condition thrombosis. Similarly, the heart inflammations myocarditis and pericarditis, which have occurred several days after vaccination in a tiny fraction of young men getting the mRNA vaccines, was already on the list.
Of course, experts say they also watch for the unexpected. Grabenstein recalls the time in when he led a smallpox vaccination effort for the U. With so many coronavirus vaccines administered in so short a time, it has actually been easier to spot incredibly rare adverse events, Yildirim says.
All rights reserved. Historically, vaccine side-effects appear right away A stroll through vaccine history confirms that even the most damaging side effects have indeed taken place within a six-week window. It is nearly twice as contagious as earlier variants and might cause more severe illness.
Children with other health conditions, such as obesity, diabetes and asthma, might be at higher risk of serious illness with COVID Getting a COVID vaccine can also help keep your child in school and more safely have playdates and participate in sports and other group activities.
After you are fully vaccinated, you can return to doing activities that you might not have been able to do because of the pandemic. You can also stop wearing a mask or social distancing in any setting, except where required by a rule or law. However, if you are in an area with a high number of new COVID cases in the last week, the CDC recommends wearing a mask indoors in public and outdoors in crowded areas or when you are in close contact with unvaccinated people.
If you are fully vaccinated and have a condition or are taking medications that weaken your immune system, you may need to keep wearing a mask. You also will still be required to wear a mask on planes, buses, trains and other public transportation traveling to, within, or out of the U.
Fact: There is no vaccine microchip, and the vaccine will not track people or gather personal information into a database. This myth started after comments made by Bill Gates from The Gates Foundation about a digital certificate of vaccine records. The technology he was referencing is not a microchip, has not been implemented in any manner and is not tied to the development, testing or distribution of COVID vaccines.
According to the CDC, mRNA vaccines work by instructing cells in the body how to make a protein that triggers an immune response. Human cells break down and get rid of the mRNA soon after they have finished using the instructions. In two animal studies, researchers performed laboratory testing of the vaccines using historically harvested fetal cell lines. However, both animal studies were conducted after these vaccines were already in phase 3 clinical trials.
Fact: It's recommended that you get a COVID vaccine if you are trying to get pregnant or might become pregnant in the future. A small number of women have reported experiencing temporary menstrual changes after getting a COVID vaccine. A small study has also shown that some women experienced temporary menstrual changes after getting COVID Further research is needed. Keep in mind that many things can affect menstrual cycles, including infections, stress, sleep problems and changes in diet or exercise.
Vaccination can also help pregnant women build antibodies that might protect their babies. Learn more about v-safe.

To maximize protection from the Delta variant and prevent possibly spreading it to others, get vaccinated as soon as you can and wear a mask indoors in public if you are in an area of substantial or high transmission.
