One of the biggest hopes is for a new vaccine that would prevent infection no matter how the SARS-CoV-2 virus mutates. 

While current vaccines, like Pfizer’s and Moderna’s mRNA shots, are highly effective at preventing serious illness and death, they are less capable of preventing Covid from spreading. 

The recent emergence of new strains, like Omicron and its sublineages BA.4 and BA.5, have led the companies to develop new jabs specifically targeted at those variants, which should be available in the fall.
