How do we know that COVID-19 vaccines are safe?
There are strict protections in place to help ensure the safety of all COVID-19 vaccines. Before receiving validation from WHO and national regulatory agencies, COVID-19 vaccines must undergo rigorous testing in clinical trials to prove that they meet internationally agreed benchmarks for safety and effectiveness.
Unprecedented scientific collaborations have allowed COVID-19 vaccine research, development, and authorizations to be completed in record time – to meet the urgent need for COVID-19 vaccines while maintaining high safety standards. As with all vaccines, WHO and regulatory authorities will continuously monitor the use of COVID-19 vaccines to confirm that they remain safe for all who receive them.
What are the side effects of COVID-19 vaccines?
Like any vaccine, COVID-19 vaccines can cause mild side effects, such as a low-grade fever or pain or redness at the injection site. Most reactions to vaccines are mild and go away within a few days on their own. More serious or long-lasting side effects to vaccines are possible but extremely rare. Vaccines are continually monitored to detect rare adverse events.
Reported side effects to COVID-19 vaccines have mostly been mild to moderate and short-lasting. They include: fever, fatigue, headache, muscle pain, chills, diarrhoea, and pain at the injection site. The chances of any of these side effects following vaccination differ according to the specific COVID-19 vaccine.
What is the link between COVID-19 vaccines and allergic reactions?
WHO is aware of reports of severe allergic reactions in a small number of people who received a COVID-19 vaccine. A severe allergic reaction – such as anaphylaxis – is a potential but rare side effect with any vaccine. In persons with a known risk, such as previous experience of an allergic reaction to a previous dose of the vaccine or any of the known components in the vaccine, precautions may need to be taken.
WHO recommends that healthcare providers assess patient medical history to determine if a patient is at risk for severe allergic reaction to a COVID-19 vaccine. All immunization providers should be trained to recognize severe allergic reactions and take practical steps to treat such reactions if they occur.
COVID-19 vaccine use will be closely monitored by national authorities and international bodies, including WHO, to detect serious side effects, including any unexpected side effects. This will help us better understand and manage the specific risks of allergic reactions or other serious side effects to COVID-19 vaccines that may not have been detected during clinical trials, ensuring safe vaccination for all.
What happens if an adverse event is reported?
As with any vaccine, it is essential to closely monitor the safety and efficacy of COVID-19 vaccines as they are delivered. If a problem is reported following vaccination, a thorough investigation should take place.
During these investigations, it is extremely rare that health problems are found to be caused by the vaccine itself. Adverse events are most often found to be coincidental and may be entirely unrelated to vaccination. Sometimes they are related to how the vaccine has been stored, transported, or administered. Such errors can be prevented by better training health workers and strengthening supply chains.
In the very rare cases where a genuine adverse reaction is suspected, the vaccine may be suspended from use. Further investigations will take place to determine what exactly caused the event, and corrective measures will be put in place. WHO works with vaccine manufacturers, health officials and other partners to monitor any safety concerns and potential side effects on an ongoing basis.
Is Corona Vaccine Safe?
Guidance says there are no safety concerns about giving jabs to people with "long" Covid either. But people who are currently unwell with Covid-19 should not receive the vaccine until they have recovered.
Is Corona Vaccine Safe? What do we know about its safety?
The U.S. vaccine safety system works to make sure that all vaccines are as safe as possible. Safety has been a top priority as federal agencies work with vaccine manufacturers to develop and authorize a COVID-19 vaccine. Here are some key areas that are part of a COVID-19 vaccine development, review and authorization:
You can learn more from the CDC about the safety steps in place for the COVID-19 vaccine.
Safety of COVID-19 Vaccines
The U.S. Food and Drug Administration (FDA) has granted Emergency Use Authorizations (EUA) for two COVID-19 vaccines which have been shown to be safe and effective as determined by data from the manufacturers and findings from large clinical trials. These data demonstrate that the known and potential benefits of this vaccine outweigh the known and potential harms of becoming infected with the coronavirus disease 2019 (COVID 19).
Clinical trials are being conducted to evaluate additional COVID-19 vaccines in many thousands of study participants. These trials will generate scientific data and other information that will be used by FDA to determine vaccine safety and effectiveness. Clinical trials on all COVID-19 vaccine candidates are being conducted according to the rigorous standards set forth by FDA in their June 2020 guidance document, Development and Licensure of Vaccines to Prevent COVID-19external icon. If FDA determines that a vaccine meets its safety and effectiveness standards, it can make these vaccines available for use in the United States by approval or through an EUA.
After FDA determines that a COVID-19 vaccine candidate is safe and effective, the Advisory Committee on Immunization Practices (ACIP), a committee comprising medical and public health experts, reviews available data before making vaccine recommendations to CDC.
