Covid-19 is likely to become as “endemic” as the annual flu virus, according to the U.K.’s chief scientific advisor.
Some potential vaccines are in late-stage clinical trials, but Patrick Vallance said none is likely to eradicate the virus.
“We can’t be certain, but I think it’s unlikely we will end up with a truly sterilizing vaccine, (that is) something that completely stops infection, and it’s likely this disease will circulate and be endemic, that’s my best assessment,” Vallance told the National Security Strategy Committee in London on Monday.
“Clearly as management becomes better, as you get vaccination which would decrease the chance of infection and the severity of disease … this then starts to look more like annual flu than anything else, and that may be the direction we end up going,” he said.
Biotech companies and academic bodies around the world have joined forces to try to create a vaccine against the coronavirus at breakneck speed given its ferocity. On Monday, the grim milestone of 40 million confirmed coronavirus cases worldwide was reached, and the virus has caused 1.1 million deaths, according to data from Johns Hopkins University.
Historically, creating a vaccine from scratch had taken 10 years on average, Vallance said, and it had never taken under five years.
“We’re now in the extraordinary situation where there are at least eight vaccines which are in quite large clinical studies around the world. … We will know over the next few months whether we have any vaccines that really do protect and how long they protect for,” he said.
He added that a number of vaccines created an immune response and…
