Market Research Biz News: A fourth COVID booster shot may be required for immunodeficiency: new CDC guidelines

Washington-According to the latest guidelines from the US Centers for Disease Control and Prevention, people in certain health conditions that cause moderate or severe immunodeficiency may get a fourth mRNA COVID-19 shot.

The CDC approved a third dose in August for certain immunocompromised patients over the age of 18. He said that immunodeficiency may not have shown a complete immune response from the first two doses, so a third dose (CDC distinguishes between the two) is needed instead of a booster.

According to a Johns Hopkins University study this summer, people vaccinated against immunodeficiency will eventually be hospitalized or die of COVID-19 compared to most vaccinated people. It was shown to be 485 times more likely to do. In a small study, fully vaccinated immunocompromised people accounted for about 44% of breakthrough cases requiring hospitalization, according to the CDC. People with immunodeficiency are also more likely to infect those who have close contact with them.

The US Food and Drug Administration has also approved booster shots of all three vaccines available for certain people, including weakened immunity, the CDC said.

Studies have shown that booster doses enhance the antibody response to vaccines in certain immunocompromised people.

It will be the fourth inoculation at least 6 months after completing the third mRNA vaccine. At this time, CDC has no recommendations for the fourth shot. According to the CDC, people need to consult a doctor to determine if it is necessary.

For people with moderate to severe immunodeficiency, those who are actively treating blood cancer or tumor cancer, recipients of specific organ transplants or stem cells, advanced or untreated HIV patients, high Includes people taking doses of corticosteroids and other medications. It may suppress their immune system. The CDC estimates that about 9 million people in the United States, or about 2% of the population, fall into this category.

People with immunodeficiency who receive a single Johnson & Johnson vaccination should receive boost immunization at least two months after the first vaccination. According to the CDC, anyone who chooses the Moderna vaccine as a booster must receive a half-dose size injection approved as a booster for the Moderna vaccine, even if they receive another vaccine as the first vaccine.

The CDC recommends that people with a weakened immune system, even if vaccinated, avoid crowded and poorly ventilated areas and wear masks in indoor public spaces.
