Can this new mutation make the vaccine ineffective?
Again, in the absence of scientific data, caution is in order. But there are many voices that say the vaccine will remain effective. Explanations. “The antibodies developed by the two main vaccines that are arriving do not target this mutated area of the virus. So, a priori, there is no reason to think that vaccines would be less effective, which is still good news.
On the other hand, the WHO questions the "effectiveness of certain diagnostic methods" without further clarification. The new strain of the virus does not call into question the effectiveness of PCR tests.
