A new study has confirmed that it’s safe to get your COVID-19 vaccine and flu shot on the same day. This finding simplifies the vaccination process and reassures people who want to protect themselves against both illnesses at once.
The research, published in JAMA Network Open, involved 335 participants from three locations in the United States. These participants, aged 5 and older, were vaccinated between October 2021 and June 2023. Most were women (63%), and their average age was about 33 years.
The study divided the participants into two groups: one group of 169 people received their COVID-19 and flu vaccines on the same day, while the other group of 166 people got the shots separately, one or two weeks apart.
Researchers monitored both groups for common vaccine side effects, such as fever, muscle aches, chills, and joint pain, during the first week after vaccination. They also checked for more serious reactions over a longer period of 121 days.
The results were encouraging. People who got both shots on the same day did not experience more side effects than those who spaced them out. Around 25.6% of participants in the same-day group reported moderate or greater side effects, compared to 31.3% in the group that received the vaccines separately.
Serious side effects, such as those requiring medical attention, were rare in both groups—8.3% in the same-day group and 12.6% in the separate-days group.
Importantly, none of the participants needed medical care for their symptoms. When asked about their overall health after vaccination, both groups reported similar levels of well-being.
The study also provided context about the participants. More than half of them (57%) had already had COVID-19 or had antibodies from a previous infection when the study began. This suggests that prior exposure to the virus did not affect how people responded to getting both vaccines at once.
These findings are significant because they offer a convenient solution for staying protected during times when both COVID-19 and flu cases tend to rise. By allowing people to get both vaccines during a single visit to the clinic, this approach could increase vaccination rates and reduce the chances of illness spreading in the community.
Vaccines are an essential tool for staying healthy, especially during seasons when respiratory viruses like COVID-19 and the flu are more active. This study shows there’s no need to make multiple trips to get protected. You can save time and effort by scheduling both vaccines together without worrying about increased side effects.
For many, this is welcome news, making it easier to prioritize health without added complications. As we prepare for seasons with higher risks of infection, the reassurance of a safe and efficient vaccination process is a step forward in managing both illnesses effectively.
