According to the World Health Organization as of April 26, 102 scientific teams across the world are working on developing a coronavirus vaccine.
Some have already begun testing their experimental Covid 19 vaccines on people.
Historically it’s taken years to do human clinical trials and get vaccines approved.
For example it took about three years to develop a polio vaccine in the 1950s.
It took about that long for the rubella vaccine in the 1960s.
And it took two years for mumps.
But no one wants to wait years for a vaccine for the novel coronavirus.
Researchers are moving with lightning speed with more than $1 billion in projected investments already pouring into the effort.
And the US FDA, which will need to approve the vaccine, has been moving faster since the pandemic began.
Which scientific team finishes first is anybody’s guess.
Doctor Anthony Fauci says getting a vaccine on the market by January could happen.
Fauci suggested that to save time, the US could manufacture some vaccines even before they have full results of clinical trials.
He admits it could be risky but it’s a risk worth taking given what’s at stake.
However vaccine trials are notoriously unpredictable.
It might turn out that a promising vaccine doesn’t work or worse, that it causes harm.
