C.D.C. Reviewing Cases of Heart Problem in Youngsters After Getting Vaccinated and AHA Reassures that Benefits Overwhelm the Risks of Vaccination

Reporter: Amandeep Kaur, B.Sc. , M.Sc.

The latest article in New York times reported by Apoorva Mandavilli outlines the statement of officials that C.D.C. agency is investigating few cases of young adults and teenagers who might have developed myocarditis after getting vaccinated. It is not confirmed by the agency that whether this condition is caused by vaccine or not.

According to the vaccine safety group of the Centers for Disease Control and Prevention, the reports of heart problems experienced by youngsters is relatively very small in number. The group stated that these cases could be unlinked to vaccination. The condition of inflammation of heart muscle which can occur due to certain infections is known as myocarditis.

Moreover, the agency still has to determine any evidence related to vaccines causing the heart issues. The C.D.C. has posted on its website the updated guidance for doctors and clinicians, urging them to be alert to uncommon symptoms related to heart cases among teenagers who are vaccine recipients.

In New York, Dr. Celine Gounder, an infectious disease specialist at Bellevue Hospital Center stated that “It may simply be a coincidence that some people are developing myocarditis after vaccination. It’s more likely for something like that to happen by chance, because so many people are getting vaccinated right now.”

The article reported that the cases appeared mainly in young adults after about four days of their second shot of mRNA vaccines, made by Moderna and Pfizer-BioNTech. Such cases are more prevalent in males as compared to females.

The vaccine safety group stated “Most cases appear to be mild, and follow-up of cases is ongoing.” It is strongly recommended by C.D.C. that American young adults from the age of 12 and above should get vaccinated against COVID-19.

Dr. Yvonne Maldonado, chair of the American Academy of Pediatrics’s Committee on Infectious Diseases stated “We look forward to seeing more data about these cases, so we can better understand if they are related to the vaccine or if they are coincidental. Meanwhile, it’s important for pediatricians and other clinicians to report any health concerns that arise after vaccination.”

Experts affirmed that the potentially uncommon side effects of myocarditis get insignificant compared to the potential risks of SARS-CoV-2 infection, including the continuous syndrome known as “long Covid.” It is reported in the article that acute Covid can lead to myocarditis.

According to the data collected by A.A.P, about 16 thousand children were hospitalized and more than 3.9 million children were infected by coronavirus till the second week of May. In the United States, about 300 children died of SARS-CoV-2 infection, which makes it among the top 10 death causes in children since the start of pandemic.

Dr. Jeremy Faust, an emergency medicine physician at Brigham and Women’s Hospital in Boston stated that “And that’s in the context of all the mitigation measures taken.”

According to researchers, about 10 to 20 of every 1 lakh people each year develop myocarditis in the general population, facing symptoms from fatigue and chest pain to arrhythmias and cardiac arrest, whereas some have mild symptoms which remain undiagnosed.

Currently, the number of reports of myocarditis after vaccination is less than that reported normally in young adults, confirmed by C.D.C. The article reported that the members of vaccine safety group felt to communicate the information about upcoming cases of myocarditis to the providers.

The C.D.C. has not yet specified the ages of the patients involved in reporting. Since December 2020, the Pfizer-BioNTech vaccine was authorized for young people of age 16 and above. The Food and Drug Administration extended the authorization to children of age 12 to 15 years, by the starting of this month.

On 14th May, the clinicians have been alerted by C.D.C. regarding the probable link between myocarditis and vaccination. Within three days, the team started reviewing data on myocarditis, reports filed with the Vaccine Adverse Event Reporting System and others from the Department of Defense.

A report on seven cases has been submitted to the journal Pediatrics for review and State health departments in Washington, Oregon and California have notified emergency providers and cardiologists about the potential problem.

In an interview, Dr. Liam Yore, past president of the Washington State chapter of the American College of Emergency Physicians detailed a case of teenager with myocarditis after vaccination. The patient was provided treatment for mild inflammation of the inner lining of the heart and was discharged afterwards. Later, the young adult returned for care due to decrease in the heart’s output. Dr. Yore reported that still he had come across worse cases in youngsters with Covid, including in a 9-year-old child who arrived at the hospital after a cardiac arrest last winter.

He stated that “The relative risk is a lot in favor of getting the vaccine, especially considering how coronavirus vaccine have been administered.”

In the United States, more than 161 million people have received their first shot of vaccine in which about 4.5 million people were between the age 12 to 18 years.

Benefits Overwhelm Risks of COVID Vaccination, AHA Reassures

The latest statement of American Heart Association (AHA)/ American Stroke Association (ASA) on May 23rd states that the benefits of COVID-19 vaccination enormously outweigh the rare risk for myocarditis cases, which followed the C.D.C. report that the agency is tracking the Vaccine Adverse Events Reporting System (VAERS) and the Vaccine Safety Datalink (VSD) for myocarditis cases linked with mRNA vaccines against coronavirus.

The myocarditis cases in young adults are more often observed after the second dose of vaccine rather than the first one, and have more cases of males than females. The CDC’s COVID-19 Vaccine Safety Technical Work Group (VaST) observed such heart complications after 4 days of vaccination.

CDC reported that “Within CDC safety monitoring systems, rates of myocarditis reports in the window following COVID-19 vaccination have not differed from expected baseline rates.”

The CDC team stated that “The evidence continues to indicate that the COVID-19 vaccines are nearly 100% effective at preventing death and hospitalization due to COVID-19 infection, and Strongly urged all young adults and children 12 years and above to get vaccinated as soon as possible.”

Even though the analysis of myocarditis reports related to coronavirus vaccine is in progress, the AHA/ASA stated that “myocarditis is typically the result of an actual viral infection, and it is yet to be determined if these cases have any correlation to receiving a COVID-19 vaccine.”

Richard Besser, MD, president and CEO of the Robert Wood Johnson Foundation (RWJF) and former acting director of the CDC stated on ABC’s Good Morning America “We’ve lost hundreds of children and there have been thousands who have been hospitalized, thousands who developed an inflammatory syndrome, and one of the pieces of that can be myocarditis.” He added “still, from my perspective, the risk of COVID is so much greater than any theoretical risk from the vaccine.”

After COVID-19 vaccination the symptoms that occur include tiredness, muscle pain, headaches, chills, nausea and fever. The AHA/ASA stated that “typically appear within 24 to 48 hours and usually pass within 36-48 hours after receiving the vaccine.”

All healthcare providers are suggested to be aware of the rare adverse symptoms such as myocarditis, low platelets, blood clots, and severe inflammation. The agency stated that “Healthcare professionals should strongly consider inquiring about the timing of any recent COVID vaccination among patients presenting with these conditions, as needed, in order to provide appropriate treatment quickly.”

President Mitchell S.V. Elkind, M.D., M.S., FAHA, FAAN, Immediate Past President Robert A. Harrington, M.D., FAHA, President-Elect Donald M. Lloyd-Jones, M.D., Sc.M., FAHA, Chief Science and Medical Officer Mariell Jessup, M.D., FAHA, and Chief Medical Officer for Prevention Eduardo Sanchez, M.D, M.P.H., FAAFP are science leaders of AHA/ASA and reflected their views in the following statements:

We strongly urge all adults and children ages 12 and older in the U.S. to receive a COVID vaccine as soon as they can receive it, as recently approved by the U.S. Food and Drug Administration and the CDC. The evidence continues to indicate that the COVID-19 vaccines are nearly 100% effective at preventing death and hospitalization due to COVID-19 infection. According to the CDC as of May 22, 2021, over 283 million doses of COVID-19 vaccines have been administered in the U.S. since December 14, 2020, and more than 129 million Americans are fully vaccinated (i.e., they have received either two doses of the Pfizer-BioNTech or Moderna COVID-19 vaccine, or the single-dose Johnson & Johnson/Janssen COVID-19 vaccine).

We remain confident that the benefits of vaccination far exceed the very small, rare risks. The risks of vaccination are also far smaller than the risks of COVID-19 infection itself, including its potentially fatal consequences and the potential long-term health effects that are still revealing themselves, including myocarditis. The recommendation for vaccination specifically includes people with cardiovascular risk factors such as high blood pressure, obesity and type 2 diabetes, those with heart disease, and heart attack and stroke survivors, because they are at much greater risk of an adverse outcome from the COVID-19 virus than they are from the vaccine.

We commend the CDC’s continual monitoring for adverse events related to the COVID-19 vaccines through VAERS and VSD, and the consistent meetings of ACIP’s VaST Work Group, demonstrating transparent and robust attention to any and all health events possibly related to a COVID-19 vaccine. The few cases of myocarditis that have been reported after COVID-19 vaccination are being investigated. However, myocarditis is usually the result of a viral infection, and it is yet to be determined if these cases have any correlation to receiving a COVID-19 vaccine, especially since the COVID-19 vaccines authorized in the U.S. do not contain any live virus.

We also encourage everyone to keep in touch with their primary care professionals and seek care immediately if they have any of these symptoms in the weeks after receiving the COVID-19 vaccine: chest pain including sudden, sharp, stabbing pains; difficulty breathing/shortness of breath; abnormal heartbeat; severe headache; blurry vision; fainting or loss of consciousness; weakness or sensory changes; confusion or trouble speaking; seizures; unexplained abdominal pain; or new leg pain or swelling.

We will stay up to date with the CDC’s recommendations regarding all potential complications related to COVID-19 vaccines, including myocarditis, pericarditis, central venous sinus thrombosis (CVST) and other blood clotting events, thrombosis thrombocytopenia syndrome (TTS), and vaccine-induced immune thrombosis thrombocytopenia (VITT).

The American Heart Associationrecommends all health care professionals be aware of these very rare adverse events that may be related to a COVID-19 vaccine, including myocarditis, blood clots, low platelets, or symptoms of severe inflammation. Health care professionals should strongly consider inquiring about the timing of any recent COVID vaccination among patients presenting with these conditions, as needed, in order to provide appropriate treatment quickly. As detailed in last month’s AHA/ASA statement, all suspected CVST or blood clots associated with the COVID-19 vaccine should be treated initially using non-heparin anticoagulants. Heparin products should not be administered in any dose if TTS/VITT is suspected, until appropriate testing can be done to exclude heparin-induced antibodies. In addition, health care professionals are required to report suspected vaccine-related adverse events to the Vaccine Adverse Event Reporting System, in accordance with federal regulations.

Individuals should refer to their local and state health departments for specific information about when and where they can get vaccinated. We implore everyone ages 12 and older to get vaccinated so we can return to being together, in person – enjoying life with little to no risk of severe COVID-19 infection, hospitalization or death.

We also support the CDC recommendations last week that loosen restrictions on mask wearing and social distancing for people who are fully vaccinated. For those who are unable to be vaccinated, we reiterate the importance of handwashing, social distancing and wearing masks, particularly for people at high risk of infection and/or severe COVID-19. These simple precautions remain crucial to protecting people who are not vaccinated from the virus that causes COVID-19.
