The J&J vaccine deals with the delta mutation. Pfizer and Moderna also report success


In addition, the latest company data show that humans are protected from dangerous variants of coronavirus for at least eight months after vaccination. An added benefit is that the Johnson & Johnson vaccine is only a single dose, so you only get one vaccination once.

“Current data from the eight months studied have shown that Johnson & Johnson’s single-dose coronavirus vaccine produces a strong antibody response that does not weaken, but improves over time,” said vaccine chief doctor Mathai Mammen, adding that the immune response against the dreaded delta and beta mutations is similar to the original virus.

Pfizer also announced strong efficacy of the delta vaccine at the end of June. “The data we have today, including from those where the Indian delta variant has replaced the British variant, shows that our vaccine is very effective. It protects about 90 percent of coronavirus,” said Alon Rappaport, director of research at Pfizer in Israel.

In June, the biotechnology company Moderna announced the effectiveness of its vaccine against coronavirus mutations. Recent research has shown that the vaccine is effective against all 16 known mutations. However, the number of antibodies in the delta is 2.1 times lower than in the original virus variant.

In contrast, the AstraZeneca coronavirus vaccine is less effective against the delta, according to some delta surveys, mainly in terms of virus transmission. According to surveys, AstraZeneca protects against the onset of symptoms in the delta variant by 60 percent. In any case, the British Ministry of Health states that the vaccine reduces the risk of hospitalization by up to 92 percent.

According to the Minister of Health Adam Vojtěch (for YES), the delta mutation is a big problem. “The delta mutation has reproduction number eight, which indicates a very infectious variant,” the minister warned.

The delta variant, formerly known as the Indian mutation, was captured by hygienists in Prague, Hradec Králové, Moravian-Silesian, Liberec and Ústí regions and in the Vysočina region. In total, laboratories have already detected 120 cases of this mutation in the Czech Republic. Mutations are currently most prevalent in India and the United States.
