This relates to the vaccine. By all accounts, the Pfizer mRNA vaccine is safe and effective, isolating an essential functional component of the virus: the surface-level spike protein. However, it presents this protein in isolation; the immune response is not as comprehensive as in actual infection. The protein's location at the surface makes it a convenient therapeutic target, but also prone to mutation. Overall, the vaccine is relatively susceptible to genetic variation.
