While anti-vaxxers are thrilled, experts warn that defunding mRNA development takes away our already-proven best weapon against future pandemics.

The US Department of Health and Human Services (HHS) plans to cancel $500m (£376m) in funding for mRNA vaccines being developed to counter viruses that cause diseases such as the flu and Covid-19.

In justifying the government's termination of $500 million in funding for mRNA vaccine projects, Health and Human Services Secretary Robert F. Kennedy Jr. falsely claimed mRNA vaccines "fail to protect effectively" against COVID-19 and suggested they are unsafe.
