COVID-19 Delta variant likely to become dominant U.S. strain, Gottlieb says - CBS News Gottlieb says the mRNA vaccines are sufficient to protect us from the Delta variant. I'm vaccinated, but will probably start taking vitamin D again and wearing a mask in crowded spaces. "The mRNA vaccine seems to be highly effective, two doses of that vaccine against this variant. The viral vector vaccines from J&J and AstraZeneca also appear to be effective, about 60% effective. The mRNA vaccines are about 88% effective," he said, referring to the vaccines developed by Moderna and Pfizer/BioNTech. "So we have the tools to control this and defeat it. We just need to use those tools."
