Pfizer's COVID vaccine has been widely applied to people. But you know what they say there is no such thing as perfection in this world. Albert Burla, CEO of Pfizer, makes a claim that will irritate many people.

According to CNBC, the CEO of Pfizer says that the effectiveness of the company's COVID vaccine will steadily drop to about 84% six months after a person gets their second dose.

Burla's comments came during CNBC's "The Exchange." It's based on the conclusions of a new study that peers have not yet revived.

The same study concluded that the Pfizer vaccine was most effective between one week and two months after receiving the second dose. The maximum effectiveness was 96.2%.

We've also seen data from Israel that there is an immunity warning, which starts to affect what was once considered 100% against hospitalization. Now, after six months, it's low in the '90s and from the mid-'80s.

The good news now is offering a third dose, a booster, which will take the immune response to levels that would be sufficient to protect against the delta variant.

Burla also said Pfizer aims to provide official data to US regulators regarding the benefits of a third dose of the COVID vaccine by mid-August.

According to the Centers for Disease Control and Prevention, clinical trials in people at least 16 years old showed that the vaccine developed by Pfizer-BioNTech was 95 percent effective for those who received two doses and were not previously infected with the COVID virus.
