Ontario recommends adults 18-24 receive Pfizer COVID-19 vaccine over Moderna due to increased risk of rare heart disease – .

Ontario now recommends that young adults only receive the Pfizer vaccine because of an apparent increased likelihood of developing rare heart disease after vaccination with Moderna.

The new ‘preferred recommendation’ for the age group was issued on Wednesday following a review of data indicating a higher rate of myocarditis and pericarditis in young adults who received the Moderna vaccine for their second dose. , especially men.

Officials say about one in 5,000 men between the ages of 18 and 24 developed the disease after receiving Moderna for his second dose, compared to about one in 28,000 men who received Pfizer instead.

About one in 17,000 women who received Moderna for their second dose also developed myocarditis or pericarditis.

“As we make this recommendation, it is important to note that myocarditis / pericarditis remains a rare adverse event after vaccination, even among the age groups with the highest observed rates,” said the Chief Medical Officer of Health. , Dr. Kieran Moore, in a briefing on Wednesday afternoon.

“The majority of reported cases have been mild, with individuals recovering quickly normally with anti-inflammatory drugs, such as ibuprofen. “

The Department of Health said people between the ages of 18 and 24 will still be able to receive the Moderna vaccine with “informed consent,” but the default will now be to administer Pfizer to this age group.

At his press conference, Moore conceded that the new recommendation “may make some people nervous” and contribute to “increased concerns about receiving COVID vaccines,” but he said it is important to remember that people who contract COVID-19 are 18 times more likely to develop inflammatory heart disease like myocarditis.

“I have three young boys, two of which are 20-24 years old and they both received Moderna and I had no fear that they would have this product,” he said. “Moderna is an excellent product, it has very good immune absorption and has achieved a very good prolonged immune response and very good protection. I have complete confidence in him.

Speaking on the merits at a technical briefing on Wednesday, ministry officials said there had been fewer than 10 cases of individuals admitted to intensive care after developing myocarditis or pericarditis after vaccination and no death.

Moore also pointed out that many people who were admitted to intensive care after developing a case of vaccine-induced myocarditis were released within days of admission once the condition was confirmed by testing.

“It is a very small number of people who had to be admitted to the intensive care unit and most of the time it is for investigation so take a blood test, a cardiogram or an ultrasound and then they are quickly sent home” , he said.

Myocarditis involves the inflammation of a heart muscle while pericarditis involves the inflammation of the thin layer of skin surrounding the heart. The most common symptoms associated with the disease include chest pain, shortness of breath, irregular heart rate, and fatigue.
