A research team at the University of Michigan Medical Center has found that people who are taking certain specific drugs will not be able to make antibodies after being vaccinated. Because these specific drugs weaken the body’s immune system and prevent the vaccine from working.
According to the Daily Mail, the team at the University of Michigan Medical Center analyzed 3.2 million US private insurers who have been vaccinated. All were adults under the age of 65. They found that about 3% of these people, or 90,000 people, had a very weak and slow response to the vaccine, or even no response. These people were all taking steroids or other immunosuppressive drugs, or some chemotherapy.
This is the metric discovered by the team, representing only a small fraction of the entire US population. Currently, the rate of first dose Covid-19 vaccine for adults in the US is about 60%, the rate of complete vaccination is about 50%. If calculated according to this percentage of the population who have been vaccinated, then after vaccination, there will be many people who have been vaccinated but the vaccine will not work. After this group of people are vaccinated, it does not mean that their body will produce antibodies to prevent infection.
Before vaccines began to be widely vaccinated, some experts questioned what to do if people did not make antibodies after vaccination. However, the expert explanation is that no vaccine is 100% effective. It seems that the vaccine’s failure to work for some people was also anticipated. Currently, the number of people studied by the University of Michigan Medical Center includes adults under age 65. Therefore, the antibody response of adolescents under 18 years of age and those over 65 years of age, after vaccination is still unknown.
Dr Deepali Kumar, head of the Infectious Diseases Clinic of Canada, said: “We know that after people are vaccinated, some people will have lower antibody production than the general population. But now we don’t know how much antibodies these people can produce after being vaccinated.”
As reported by the University of Michigan team, people who do not develop antibodies or have weak antibodies after vaccination, usually because they have the following diseases, and receive treatment or take the following drugs:
Cancer patients and patients with autoimmune diseases being treated, eg multiple sclerosis, lupus erythematosus, rheumatoid arthritis, Crohn’s disease (some inflammatory bowel diseases), etc.
People who are already taking certain steroid medications for arthritis, inflammatory bowel disease, etc. These people should also be especially aware that these drugs can inhibit antibody production. If you have been vaccinated, you should still prevent infection. If not vaccinated, it is best to consult your doctor first.
According to the research team, the above-mentioned people have very low resistance, are susceptible to infectious diseases, colds, etc. Therefore, everyone should note, if a loved one has this disease or takes this medicine at home, must pay attention to the prevention of epidemics.
