According to this article from Ed Browne at Newsweek, experts believe another COVID vaccine could be needed. This additional vaccine would be tailored specifically to the Delta variant.
This suggestion comes after a study indicated the Delta variant is “eight times less sensitive to the antibodies that vaccines provide” compared to earlier versions of the COVID virus. In other words, the article explains that it would take more antibodies to block the Delta variant of the virus than the earlier versions previously seen. This extra resistance is likely the explanation for many vaccine breakthrough cases.
Although the vaccine has provided many with relief and reassurances, we must remain cautious. We encourage everyone to remember to seek out information from experts, follow various guidelines, and remain as safe as possible.
