Tis theseasonto get vaccinated ! We in the Northern Hemisphere are rapidly approach the shortest day of the year , and that means it ’s time to think about protect yourself against the flu and COVID-19 . It would be convenient to get both shots at the same time , but is it secure ? Yes , is the resounding determination from a young work .

Both flu and COVID-19 vaccinum are currently commend in the US – where the survey was conducted – for adults and kid over the eld of 6 months .

The optimal time to get your seasonalflu shot , according to theFood and Drug Administration(FDA ) , is right now : flu activeness peak between December and February , so it ’s definitely not too previous to get protect .

COVID-19 , as we live , does n’t follow the sameseasonal patternas the influenza – but during the year of the pandemic , we ’ve reliably seenpeaksin infections in the winter . If you have n’t yet had an updated 2024 - 25 COVID-19 shot , theCenters for Disease Control and Prevention(CDC ) say you may get one – for most people , you just have to look two months since your last promoter .

To get as much coverage of these two vaccines as potential , clinicians in the US are permit to administer both of them at the same time , but the authors of the new written report point out that when they planned their enquiry , there was limited hard scientific data around this access .

As such , the authors lead a clinical trial during two flu season – 2021 - 22 and 2022 - 23 – at three site : Cincinnati Children ’s Hospital Medical Center , Duke University , and The Johns Hopkins University .

In the end , they obtained data point from 334 masses who received both an mRNA COVID-19 vaccinum and an inactivated grippe vaccine formulated for that particular season . The subjects were randomize to meet the two shots either consecutive or simultaneously .

The primary outcome the researchers were look at was reactogenicity – did the participants experience vernacular reading of an immune reaction like fever and musculus pains , and did this happen more often in those getting both stroke together ? They also looked at other inauspicious effect occurring in the seven day immediately travel along each vaccine , as well asserious adverse eventswithin the following 121 24-hour interval .

“ Approximately 10.7 percentage to 26.8 percent of participants in the trial reported restrained or severe injection site pain , fatigue , myalgia , cephalalgia , or chills after receipt of mRNA COVID-19 vaccinum , ” the authors write , which they take down is what you would carry to see ground on examination of these vaccine prior to licensing . The incidence ofside effectsfrom the grippe vaccines was also within expectations .

After analyzing the data , the team found that reactogenicity was comparable across both the sequential and simultaneous radical . There was no evidence of any refuge concerns with giving both vaccine at the same clock time , and the participants did n’t react any worse , on average , than those whose shot were space out .

One key limitation they note is that the survey was underpowered – due to logistical issues , they were n’t able-bodied to recruit as many participant as they would have like . They also note that they contrive a future study focusing on meaning people , who were excluded from this research .

Overall , though : “ This trial lends support to the choice of simultaneous governing body of these vaccinum , ” the authors conclude , “ which is a scheme to achieve eminent levels of vaccination insurance coverage during anticipated periods of increased grippe and SARS - CoV-2 computer virus transmission . ”
