Jakarta, CNBC Indonesia – The Covid-19 vaccine booster has proven to be a valuable contribution so that the world can return to normal activities.
Research published August 11 in the journal eBioMedicine reveals the secret of a powerful booster vaccine that strengthens antibodies and kills viruses in the body. The study found that the vaccine booster would have a stronger immune response because it was injected in the same hand.
Study co-author Martina Sester who is also a biologist and head of the department of the Institute of Infectious Medicine at the Saarland University Hospital in Germany also researched the new version of the vaccine using data on 303 people who received the mRNA vaccine as well as a booster shot as part of the German vaccine campaign.
The result, two weeks after the booster, those who got the second injection in the same hand experienced a higher increase in the number of killer ‘T cells’ significantly. 67% of people after using the new booster vaccine now have cells that attack and destroy the ‘T virus cells’ they target.
As for immune strength with booster injections in different hands, only 43% of the objects are successful.
Professor in the Division of Infectious Diseases at Vanderbilt University Medical Center in Nashville, Dr. William Schaffner describes stronger immune efficacy if the booster is injected in the same hand.
According to him, the cells that provide an immune response are in the local lymph nodes. Lymph nodes are located all over the body including the neck, chest, abdomen and armpits. If the immune cells in the lymph nodes are stimulated again in the same place, a greater immunological response will occur.
The study also showed that antibodies in people using boosters on the same hand were better at binding to the virus’ spike protein. The spike protein is responsible for the entry of the coronavirus into cells, according to the National Institutes of Health.
While the study suggests a greater immune response, the researchers can’t say for sure that giving a booster to the same hand will result in better or longer-lasting protection.
“We won’t know unless we do a larger clinical study with a follow-up of the actual infection,” said Schaffner.
