These boosters are designed to protect against disease caused by the original strain of the SARS-CoV-2 virus, as well as the Omicron subvariants BA.4 and BA.5 (although experts are still learning about their effectiveness against the latest Omicron subvariants). A major reason is Omicron has accumulated over 50 mutations, including about 30 in the spike protein, the part of the coronavirus that mRNA vaccines teach our immune systems to attack.
