Can We Stop COVID-19 From Out-Evolving a Vaccine?
The first drug against HIV brought dying patients back from the brink. But as excited doctors raced to get the miracle drug to new patients, the miracle melted away. In each and every patient, the drug only worked for a while.
It turned out the drug was very good at killing the virus, but the virus was even better at evolving resistance to the drug. A spontaneous mutation in the virus' genetic material prevented the drug from doing its work, and so the mutant viruses were able to replicate wildly despite the drug, making the patients sick again.
It took another decade before scientists found evolution-proof therapies.
Could the same thing happen to a COVID-19 vaccine?
Could the SARS-CoV-2 coronavirus mutate into a form that is resistant to the COVID-19 vaccines being developed?
