Is there is a third dose of Pfizer/BioNTech Covid-19 vaccine?

Doctors said a third dose of the Pfizer vaccine could "powerfully" enhance protection against the delta variant -- other than the protection offered by the two standard doses, new data released by Pfizer on Wednesday indicates.

These data, expected to be discussed on the company's earnings call Wednesday morning, indicates that antibody levels against the delta variant in people ages 18 to 55 who receive the third dose of corona vaccine are more than five times greater follows. The second dose.

Among people aged 65 to 85, Pfizer data indicate that antibody levels against the delta variant after receiving the third dose are more than 11 times greater than after a second dose.

In Pfizer's data slides, the researchers wrote, there is an "estimated potential for up to a 100-fold increase in delta reduction after the third dose compared to the previous three doses."

The data has not yet been reviewed or published.

Experimental research data also shows that antibody levels are significantly higher after a third dose than the second dose versus the original coronavirus variant and beta variant, first identified in South Africa.
