The White House's top infectious disease expert warns new coronavirus vaccines could make Covid-19 symptoms more dangerous. Dr Anthony Fauci told Congress yesterday some people could end up catching the virus from vaccines and becoming "seriously ill" rather than better.
While those who already have the virus could become even more ill. In a televideo conference at a US Senate hearing, he said: "I must warn that there’s also the possibility of negative consequences, where certain vaccines can actually enhance the negative effect of the infection." He added in some rare cases people vaccinated would see their immune systems go into overdrive.
