Published studies show no association between COVID-19 vaccines … – Health Feedback
October 19, 2023

CLAIM

COVID-19 vaccines increase the risk of heart attacks

DETAILS

Inadequate support: Apart from a heavily flawed conference abstract and an unverifiable claim from a whistleblower, no data or evidence was provided by Malhotra to support the suggestion that COVID-19 vaccines increase heart attack risk. Cherry-picking: Several studies have already shown that COVID-19 vaccination isnt associated with a greater risk of heart attack. No mention of these studies were made in the video.

KEY TAKE AWAY

Like all medical interventions, COVID-19 vaccines can produce side effects. Most of these side effects are mild and short-lived. More serious risks, such as a rare blood clotting disorder and a type of heart inflammation have also been associated with certain COVID-19 vaccines, but are rare. The risk of heart problems and blood clotting, just to name a few, is greater with COVID-19 than with the vaccines. By reducing the risk of infection and severe disease in people, the vaccines benefit outweighs their risk.

Prior to the pandemic, Malhotra was known for promoting controversial claims about the benefits of the Pioppi diet. He also claimed that statinsdrugs used to reduce cholesterol levelsprovide no benefit to patients with high cholesterol.

In September 2022, Malhotra published an article in the Journal of Insulin Resistancea journal of which he is an editorsuggesting that COVID-19 vaccines are more harmful than helpful and that they increase the risk of cardiovascular disease.

Malhotras article was panned by other scientists, who pointed out that its argument relied on cherry-picked studies with methodological flaws, anecdotal data and anonymous sources, but excluded data contradicting the articles argument. Health Feedback wrote about the article in an earlier review.

In January 2023, during an interview with the BBC, Malhotra suggested that excess deaths linked to heart disease were linked to COVID-19 vaccines. This conduct was criticized by experts, and the BBC later aired an interview with physician and scientist Peter Openshaw, who pointed out that the risks of COVID-19 were greater than that posed by the vaccines.

Malhotras interview with Rogan took place in April 2023, during which Malhotra proceeded to air the same views as he had done before on COVID-19 vaccines. In the run-up to his whistleblower claim, Malhotra cited a conference abstract by cardiothoracic surgeon Steven Gundryhimself a controversial figureand news that Scotland had seen a 25% increase in heart attacks in summer 2021.

However, Gundrys abstract had actually received an Expression of Concern from the journal on 24 November 2021, a few months before Malhotras appearance on Rogans show.

The notice stated that there is no data in the abstract regarding myocardial T-cell infiltration, there are no statistical analyses for significance provided, and the author is not clear that only anecdotal data was used. In other words, no evidence was presented for the claims made in the abstract. The abstract was later corrected, removing its initial claim of dramatically increase[d] inflammation and clarifying that no statistical comparisons were performed.

Because the interview doesnt provide any information about the whistleblower, nor does it provide a publicly available source for the alleged data showing increased inflammation of the arteries of the heart, we are unable to verify this claim. We reached out to Malhotra for comment and will update this review with new information if available.

But we can look at whether the broader claim that COVID-19 vaccines raise heart attack risk is supported by evidence so far.

Published studies dont support this claim. A study performed in Israel and published in the New England Journal of Medicine didnt find a higher risk of heart attack in vaccinated people relative to unvaccinated people[1].

Figure 1. The relative risk of various adverse events after vaccination or SARS-CoV-2 infection. Adapted from the original figure by Barda et al. Note that the effects of vaccination and of SARS-CoV-2 infection were estimated with different cohorts: vaccinated people were compared with unvaccinated people, while those who tested positive for SARS-CoV-2 were compared with uninfected people. Thus, the risks from vaccination and that of infection cannot be directly compared.

Another study performed in the U.S. found no association between COVID-19 mRNA vaccination and heart attack[2].

Studies performed in France also didnt find a higher risk of heart attack in those above 75 years old[3] and in younger cohorts[4].

A study in Hong Kong didnt find a greater risk of heart attack in people with heart disease whod been vaccinated against COVID-19[5].

Moreover, COVID-19 vaccination is associated with a lower risk of developing a heart attack after SARS-CoV-2 infection, as one study in the U.S.[6] and another in South Korea reported[7]. In contrast, getting COVID-19 itself is a risk factor for developing cardiovascular problems, as studies have already reported[1,8].

The American Heart Association states that People with cardiovascular risk factors, heart disease, and heart attack and stroke survivors should get vaccinated because they are at much greater risk from the virus than they are from the vaccine.

In brief, numerous published studies havent found that COVID-19 vaccines increase the risk of a heart attack and their findings overturn Malhotras suggestion that theres reason to believe otherwise.

British comedian Russell Brand made a similar claim that COVID-19 vaccines caused a rise in heart attacks in young people. Health Feedback debunked the claim here.

Symptoms – COVID-19 – Government of Newfoundland and Labrador
October 13, 2023

Symptoms of COVID-19 are defined as:

If you have symptoms, stay at home until your symptoms have improved and you havent had a fever for at least 24 hours.

You may choose to use a rapid self-test if you have them on hand.

If you are at higher risk of severe disease, you should test for COVID-19 because, if positive, you may be eligible for early treatment.

Rapid Self-Testing Instructions

Repeat testing improves accuracy. If the first rapid self-test is negative, and you continue to have symptoms, do another test 48 hours later.

If you choose to get tested and you test positive, stay at home until your symptoms have improved and you havent had a fever for at least 24 hours. Contact your primary care provider or pharmacist if you think you may be eligible for COVID-19 treatments.

When you are feeling better and leave home, for 10 days after your symptoms started, you should:

Frequently Asked Questions – COVID-19 – Government of Newfoundland and …
October 13, 2023

It is recommended that individuals over the age of 60 and those with underlying medical conditions who are at increased risk for severe illness avoid going out in public as much as possible. If they have to go out in public, they are reminded to wash their hands frequently, wear a non-medical mask or cloth face covering, avoid crowds, and limit time spent outside the home.

Health care workers who are immunocompromised or have underlying medical conditions do not need to be restricted from providing care to patients who are under investigation for COVID-19, or who are a presumptive or confirmed case of COVID-19, as long as they are able to:

Health care workers who are unable to competently adhere to infection prevention and control recommendations for COVID-19 (e.g. those with a skin condition that precludes proper hand hygiene practices) should not provide care to patients who are under investigation for COVID-19, or who are a presumptive or confirmed case of COVID-19.

Health care workers who are immunocompromised should be assessed by management on a case-by-case basis.

Variants – COVID-19 – Government of Newfoundland and Labrador
October 13, 2023

Viruses such as SARS-CoV-2 naturally mutate or change over time. Most of these mutations do not change the characteristics of the virus. However, some mutations can affect virus characteristics in a meaningful way, leading to a variant of concern. We are most concerned about changes that affect these factors:
