A new study shows two doses of the Pfizer vaccine appears to offer high protection against combating the delta variant.

The study published in the New England Journal of Medicine says the Pfizer vaccine is 88% effective against preventing symptomatic disease from the strain.

Researchers did say that one shot of the vaccine is not nearly as effective at stopping the virus.

Moderna's, which also uses mRNA, is said to be more effective against delta when compared to the one-dose shot from Johnson & Johnson.
