CDC: Some people may need the third dose of COVID-19 vaccine
CDC: Some people may need the third dose of COVID-19 vaccine. The CDC COVID-19 expert team said on Wednesday that there is not enough data to prove that it is necessary for ordinary people to inject COVID-19 booster needles, but the elderly or people who have received organ transplants may need it.
The COVID-19 Working Group of the CDC Advisory Committee on Immunization (ACIP) said that it has not safely ruled out the possibility of boosting needles. They said that if the vaccine’s immunity is weakened or the mutated virus reduces the effectiveness of the current vaccine, the general population may eventually need a booster.
A study recently published by Johns Hopkins University researchers in the Annals of Internal Medicine showed that booster injections may be beneficial for people with weakened immune systems. Sarah Oliver, a medical epidemiologist at the CDC’s National Center for Immunization and Respiratory Diseases, said that residents of long-term care facilities, the elderly, medical staff, and people with weakened immune systems need special monitoring.
Panel member Sharon Frey, clinical director of the Vaccine Development Center at St. Louis University School of Medicine, said: “I very much agree with the working group’s explanation that there is currently no data to support the recommendation to strengthen the needle.”
But Frey said she recommends a third injection for patients who have had organ transplants. Another situation is that if there is a significant increase in the number of breakthrough cases in the general population, that is, the number of infections after the vaccine has been completed, then a third injection is also required. According to CDC data, so far, there have been 3729 breakthrough infections in the United States, leading to hospitalization or death.
Grace Lee, chair of the ACIP safety team and professor of pediatrics at Stanford University School of Medicine, also said that she hopes to see more evidence of breakthrough cases before discussing intensified needles. She said that if you see a serious breakthrough case, then it’s time to start a discussion of intensified needles.
