New Negative: Delta Plus

South Korea has reported its first 2 cases of the “Delta plus” COVID-19 variant—both had been fully vaccinated with the AstraZeneca jab, officials said Tuesday, The Korea Herald reports.
 
Delta plus was first discovered in Europe in March and has also been spotted in several countries including the UK, the US, and India, The Washington Post reports.
 
Take note: South Africa halted use of the AstraZeneca shot in February after the Beta variant was shown to evade some of the vaccine’s powers. mRNA shots fared better against Beta.
 
South Korea needs to keep a close eye on Delta plus—but breakthrough cases should not be used to discredit vaccines, warns Korean Vaccine Society’s vice president Chun Byung-chul. 
 
While it’s too soon to know whether Delta plus could evade vaccines and whether it is more infectious, its emergence is yet another reminder that vaccines are the best defense to stop mutations.  
 
The Quote: “The virus is not going to wait around for us to get our act together,” said James E.K. Hildreth of Meharry Medical College.
