Johnson & Johnson said on Wednesday that a second sound COVID-19[female[feminine vaccine eight months after the initial dose was found in a study to increase people’s immunity to the disease.

The drugmaker has tested the effectiveness of the boosters in people who have previously received an injection of its single-dose vaccine. The latest findings show that people who received an additional injection saw their antibody levels rise nine times, according to J&J. The company said the researchers observed a “rapid and robust” rise in antibodies in people aged 18 to 55 and in those 65 and older who received a lower booster dose.

While the company’s single-injection vaccine stimulates a strong immune response, “With these new data, we also see that a booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses in participants in the ‘study that had previously received our vaccine, “said Dr Mathai Mammen, global head of research and development at Janssen Pharmaceuticals of Johnson & Johnson, in a statement.

“We look forward to discussing with public health officials a potential strategy for our Johnson & Johnson COVID-19 vaccine, increasing eight months or more after primary single-dose vaccination,” he added.

J&J said he was working with the Food and Drug Administration, the US Centers for Disease Control and Prevention, the European Medicines Agency and other health agencies to roll out booster shots.

The Food and Drug Administration announced on Monday that it had granted full approval to Pfizer and BioNTech for their COVID-19[female[feminine vaccine to be administered to Americans from the age of 16.

About 13.8 million Americans have received J&J’s coronavirus vaccine. Although studies suggest that the degree of immunity conferred by the Pfizer and Moderna vaccines wanes over time, these studies have ruled out J & J’s vaccine.

Yet several studies – ranging from antibody research that have yet to be peer-reviewed to anecdotal reports of more hospitalizations in outbreaks among those vaccinated – have raised concerns. that J & J’s vaccine offers weaker protection to the highly contagious Delta variant.

The White House said last week that Americans who received injections of Pfizer and Moderna should receive booster shots eight months after their second dose, and at the same time said recipients of the J&J vaccine would eventually also need an extra shot.

With the Delta variant ravaging vast areas With Southern U.S. and COVID-19 Cases Rising in Other States, More Employers and Government Entities Are Heading To require workers to be vaccinated. Lawyers say FDA approval of the Pfizer-BioNTech vaccine this week will likely prompt many companies to compulsory vaccines.
