Researchers working to develop a vaccine against COVID-19 must consider a few things.
The inevitable mutation of the virus is one of the most important considerations, says UPI.
They must also monitor its evolution to ensure that inoculations continue to prevent infection.
New vaccines could become available as early as later this year.
Researchers should use virus samples collected during testing to check for new strains.
New strains could mean that the virus may not respond to the vaccine formulation.
