LONDON : Will one dose of a two-dose COVID-19 vaccine protect me? Yes, but not nearly as much as if you had both doses.
Experts recommend getting fully vaccinated, especially with the emergence of worrisome coronavirus mutations such as the delta variant first identified in India.
The Covid-19 vaccines rolling out globally were developed to target the original version of the virus detected in late 2019.
While they seem to work against newer versions, there's a concern the shots eventually might lose their effectiveness if variants evolve enough.
