The World Health Organization has called on nations to delay their plans for booster shots till countries with lower vaccination rates can vaccinate more of their population. Just over 14 million individuals have received the Johnson & & Johnson vaccine, the smallest share among the three vaccines being used in the U.S., according to the Centers for Disease Control and Prevention. The Pfizer vaccine has been administered to more than 205 million people, and almost 144 million have gotten the Moderna shot, the CDC said.

Several independent researchers said the finding would probably support giving people boosters with the Johnson & & Johnson vaccine. “It would be sensible to say that yes, have at least 2 doses of J&J, or have at least one more dosage for those who had a single dosage, including the option of having another J&J,” stated Saad Omer, a vaccine scientist at Yale. “It is pointing toward the utility of a 2nd dose.

The Biden administration has actually already announced strategies to start rolling out boosters in September for people who got the Moderna and Pfizer vaccines. Individuals 18 years and older who got the Pfizer or Moderna vaccines will be eligible for a booster dose 8 months after their second dosage.

Johnson & & Johnson says it has evidence that people who got its one-shot COVID-19 vaccine might take advantage of a booster shot after 6 months. The pharmaceutical giant said in a news release Wednesday that when it gave individuals in a study a 2nd jab of its coronavirus vaccine after six months, their antibody levels were 9 times higher than 28 days after their very first dosage. If the vaccines efficiency starts to wane, the data suggests that an additional shot may serve as a booster.

” We have developed that a single shot of our COVID-19 vaccine produces strong and robust immune reactions that are durable and relentless through eight months,” said Mathai Mammen, international head of Janssen Research & & Development, Johnson & & Johnson, in a statement. “With these new data, we also see that a booster dosage of the Johnson & & Johnson COVID-19 vaccine additional boosts antibody responses among study individuals who had actually previously received our vaccine,” he added. The information have not yet been published in a scientific journal or reviewed by other researchers.
