FDA chief addresses reports Covid vaccine to get strongest warning as it investigates adult deaths

The US Food and Drug Administration (FDA) has responded to reports that they were planning on putting their strongest possible warning on the Covid vaccine.

CNN had reported that the FDA had been intending to put a warning on the vaccine in a move which would shock experts, since there would be no scientific basis for the warning.

Many medications do come with a boxed warning, including ones which contain opioids and some antidepressants, though a serious warning does not mean that a drug or medication is banned from use.

Concerns were raised over a possible link between the vaccine and side effects of myocarditis and pericarditis, conditions involving inflammation of the heart's muscle and wall respectively which can occur after the body has fought off a viral infection.

It is believed to be a very rare side effect of the Covid jab affecting up to one in 10,000 people vaccinated, and when it comes to a warning going on the box, FDA Commissioner Marty Makary told Bloomberg 'we have no plans to put that on the Covid vaccine'.

"It may be different today than it was in the first year of Covid when the shot came out," he said, explaining that due to a changing understanding in the possible risks they wouldn't be putting a strong warning on the box.

"When you have those two doses three months apart, that’s when you the see side effects go way up, like myocarditis in young people.

"Now that’s annual, you may not see that same prevalence. So we don’t want to extrapolate findings to today if it’s not transferable."

The FDA is also investigating whether the Covid vaccine caused deaths in adults after their Chief Medical and Scientific Officer Vinay Prasad claimed with no evidence that the vaccine had killed 10 children.

"FDA is doing a thorough investigation, across multiple age groups, of deaths potentially related to COVID vaccines," US Department of Health and Human Services press secretary Emily Hilliard said in a statement to The Guardian.

She said there would be more information 'soon' and claimed that 'previous FDA leadership failed to properly investigate' deaths which may have been linked to the vaccine.

Studies on the health effects of the Covid vaccine on around 40 percent of France's population found that people who took the vaccine had a 74 percent lower chance of dying from the deadly disease.

Research from the American Heart Association found that the risk of myocarditis from the Covid vaccine was much lower than the risk of getting it from actually having had Covid.

The Covid vaccine is still available for people in the form of booster shots, and in the UK the NHS says 'it's important to top up your protection' as 'viruses change and protection fades over time'.
