It’s vaccination season, which for most individuals means getting immunized for flu and COVID-19 (and RSV for infants, pregnant girls, or folks 75 and older).
Public-health officers have mentioned earlier than that getting the 2 pictures on the identical time is secure, however some folks have remained nervous about receiving each vaccines collectively. Now, a brand new research confirms that security. In what the researchers say is the primary randomized, placebo-controlled trial analyzing the negative effects of the co-administration of the vaccines within the U.S., they discovered no distinction amongst individuals who obtained the COVID-19 and flu pictures concurrently in numerous arms and those that received the pictures spaced aside by per week or two.
Dr. Emmanuel Walter, chief medical workplace of the Duke Human Vaccine Institute and professor of pediatrics at Duke College Faculty of Drugs, and his group studied 335 individuals who have been randomly assigned over two visits to obtain a COVID-19 mRNA vaccine and both a placebo flu shot or an precise flu shot. The visits have been spaced one to 2 weeks aside.
Unwanted effects, most of which have been delicate, aren’t uncommon for these pictures. Some folks reported issues like ache on the injection website, fever, muscle and joint aches, headache, chills, fatigue, nausea, and swelling beneath the arms throughout the seven days following the pictures.
However Walter and his group discovered no distinction between the 2 teams within the charges of those negative effects, and no distinction in quality-of-life surveys given to each teams.

“The underside line is that once we gave the vaccines collectively, we didn’t see a rise within the composite consequence of negative effects once we unfold them out over two visits,” says Walter.
Some consultants have speculated that activating the immune system towards two viruses concurrently may result in barely extra reactions, however that wasn’t the case within the research. The outcomes assist present suggestions from the U.S. Facilities for Illness Management and Prevention that receiving the COVID-19 and flu pictures on the identical time is secure.
The charges of negative effects have been additionally related no matter whether or not folks had had COVID-19 earlier than or not—additional supporting the protection of getting concurrently vaccinated.
The present research didn’t discover whether or not the co-vaccination impacts the effectiveness of both vaccine. There was some trace within the knowledge that individuals who received the pictures collectively may need extra COVID-19 sickness, however the affiliation wasn’t statistically important. Walter says he collected antibody data from the volunteers and plans to investigate the information extra absolutely to reply that query in a future research.
Due to the small dimension of the research, he additionally was not in a position to absolutely decide if uncommon, extra extreme adversarial occasions related to both vaccine have been additionally related amongst those that obtained the 2 pictures on the identical time vs. individually.
“When this research was designed, we didn’t have any data on the protection of giving each [of these] vaccines collectively,” he says, though the long-standing secure follow of giving younger youngsters a number of vaccines on the identical time advised there was no cause for concern. “The outcomes assist that it’s okay for folks to get each vaccines within the comfort of 1 go to fairly than splitting them up into two visits.”
