The COVID-19 vaccine could consist of two shots says Edwards
A vaccine against the coronavirus may not be as simple as one jab and you’re immune.
There’s a high likelihood an eventual vaccine will require a two-dose series, a month or so apart, with the possibility of a booster several years later, adding to the complexity and cost of administration and distribution.
“The MERS serology data suggest that by about three years, it could fade,” said Dr. Kathryn Edwards, a professor of pediatrics at Vanderbilt University and scientific director of the Vanderbilt Vaccine Research program.
Whether the same will be true of SARS-CoV-2 isn’t yet known. If it is, a booster injection might be needed after a couple of years.
“Only testing will tell,” Edwards said.
