United States is considering a way to get the Modena and Pfizer vaccines three times to maximize the effectiveness of the vaccine. I think a conclusion will come out around this fall. The decision to resume use in the U.S. for Janssen vaccine, which was temporarily suspended due to a blood clot side effect, will soon be decided.

Dr. Pouch, the highest authority on Corona 19 in the United States,

said that

judgments on additional vaccinations and booster shots will be made at the end of this summer or at the beginning of autumn.



He explained that the US health officials would decide for themselves, not the pharmaceutical company.



Earlier, Modena and Pfizer entered a boostershot clinical trial to maximize the effectiveness of the vaccine as concerns over the mutant virus grew.



[Jax/Modena Chief Medical Officer: By the end of this year, we expect that preparations will be over to supply booster shots for building the immune system we need.] As the



US sweeps away both Pfizer and Modena vaccines There is growing concern that the vaccine shortage in countries around the world will be further aggravated once the decision is made for a booster shot.



The Janssen vaccine, which had been discontinued in the United States due to a blood clot side effect due to an overwhelming attack, is expected to resume use soon, conditionally.



[Pouch/U.S. National Allergy and Infectious Diseases Research Center: It is expected that the Janssen vaccine can be reused in any form. If there is a decision to cancel, it's a serious situation, and that won't happen.]



With more than half of all adults over the age of 18 in the U.S. getting vaccinated at least once, the U.S. health authorities have planned to ensure that children of all ages will be vaccinated by the first quarter of next year.
