The United States has approved a booster dose of Corona Ticker

Desk report:  The US Food and Drug Administration (FDA) has approved the use of coronavirus ticker booster or third dose. The approval was given last Thursday (August 12), local time, CNBC reported.As a result, Pfizer Bioentech and Modern will make the third dose of the vaccine. However, in the fight against corona, only those who have a weakened immune system will be given this dose.The United States is approving a booster dose of corona vaccine for those with weakened immune systems, CNN reported Wednesday. The FDA may make the announcement in the next 48 hours. The third dose was approved 48 hours later.Doctors in the United States say it is becoming increasingly clear that many people are at risk even after being vaccinated. This is because their immune system is not strong enough to protect against corona. According to the CDC, 2.8 percent of vaccinators in the United States have had their coronary immune system weakened or damaged. Pfizer has been researching ticker booster doses for several days. Last July, Pfizer Bioentech was producing more antibodies against the third-dose corona variant, the beta variant, and the variant identified in South Africa, the company said. Two to three doses of coronary vaccine produce 5 to 10 times more antibodies than the third dose. At the time, Pfizer also said it would be necessary to take a third dose within 6 to 12 months after taking two doses of the vaccine. The reason, they said, is that a high level of protection is available for up to six months after taking two doses of the vaccine or a full vaccine. After that, the effectiveness of the ticker decreases over time.
