FDA intends to put most serious warning on Covid-19 vaccines, CNN reports

WASHINGTON - The US Food and Drug Administration (FDA) intends to put a ‘black box’ warning on Covid-19 vaccines, CNN reported on Dec 12, citing two people familiar with the agency’s plans.

The warning is the most serious type and highlights major risks such as serious side effects and restrictions.

The plan to include the warnings for Covid-19 shots is being orchestrated by Dr Vinay Prasad, the FDA’s chief medical and scientific officer and director of the agency’s Centre for Biologics Evaluation and Research, the report added.

“Unless the FDA announces it, any claim about what it will do is pure speculation,” US Department of Health and Human Services spokesman Andrew Nixon said about the plans to include the warning.

Following the CNN report, vaccine maker Moderna pointed to a statement it issued in September about the safety of its Covid-19 shot.

Pfizer also reiterated a statement that its vaccine continues to demonstrate a favourable safety and efficacy profile supported by extensive real-world evidence.

Dr Prasad told staffers in a memo in November that Covid-19 shots probably contributed to the deaths of at least 10 children who died of heart inflammation.

The FDA is investigating

deaths potentially related to Covid-19 vaccines

across multiple age groups as part of a safety review, a HHS spokesperson said on Dec 9.

FDA Commissioner Marty Makary has previously said the agency was looking at such deaths in young people.

Health Secretary Robert F. Kennedy Jr,

a long time vaccine sceptic

, has sharply changed government policy on Covid-19 vaccines, limiting access to people aged 65 and above, as well as those with underlying conditions.

The plan to add the warning has not been finalised and may still change, CNN reported.

It was not immediately clear whether the plans for the warnings, expected to be unveiled by the end of 2025, would be applied only to mRNA vaccines or all Covid-19 vaccines, and if they would apply to all age groups, the report added.

Vaccines from Pfizer and partner BioNTech and Moderna use messenger RNA technology, while Novavax’s shot is a more traditional protein-based one. REUTERS
