5 hours ago As the frontline system for vaccine safety monitoring, VAERS depends on healthcare professionals to report any health problems of clinical significance that may occur after vaccination. Healthcare providers should report suspected adverse events following vaccination to VAERS for all vaccines currently licensed for use in the United States, and all COVID-19 … >> Go To The Portal
Reactions were reported most frequently on the day after vaccination for both doses. The most frequently reported reactions after either dose were injection site pain, fatigue, and headache. Fever was more frequently reported after dose 2 (4,001; 13.4%) than dose 1 (3,350; 7.9%).
If you need additional help submitting a report, you may call the VAERS toll-free information line at 1-800-822-7967 or send an email to info@vaers.org.
If you get a COVID-19 vaccine and you think you might be having a severe allergic reaction after leaving the vaccination provider site, seek immediate medical care by calling 911.
In addition, you can report side effects to ModernaTX, Inc. at 1-866-MODERNA (1-866-663- 3762). You may also be given an option to enroll in v-safe.
The known risks of COVID-19 illness and its related, possibly severe complications, such as long-term health problems, hospitalization and even death, far outweigh the potential risks of having a rare adverse reaction to vaccination like myocarditis or blood clots.
Monitoring of the Moderna COVID-19 vaccine has found 10 cases of anaphylaxis after the administration of 4,041,396 first doses of the Moderna COVID-19 vaccine. In 9 out of these 10 cases of anaphylaxis, the recipient of the vaccine had onset of symptoms within 30 min of administration.
Symptoms of anaphylaxis often occur within 15-30 minutes of vaccination, though it can sometimes take several hours for symptoms to appear.
An immediate allergic reaction happens within 4 hours after getting vaccinated and could include symptoms such as hives, swelling, and wheezing (respiratory distress).
Delayed urticarial reactions — Occasionally, patients develop a few hives and/or mild angioedema several hours or days after administration, as with other vaccines.
Common symptoms include local pain, redness, swelling, systemic tiredness, headache, muscle pain, fever, and nausea. Regulating authorities are suggesting facial paralysis and swelling as possible orofacial adverse effects of the COVID-19 vaccine, which is assumed to occur rarely [6].
This is normal and expected, but it doesn't happen to everyone. Even if you feel worse after the second shot, the side effects should still resolve within a few days.
“Overall, severe allergic reactions to COVID-19 mRNA vaccines, including life-threatening anaphylaxis reactions such as low blood pressure and difficulty breathing, are rare, on the order of five cases per million vaccine doses administered,” noted Dr. Guerrerio.
