Is it safe to inoculate the influenza and new corona vaccines at the same time?

Influenza pandemic is predicted in winter, but many people are worried about the overlap between vaccination against the new coronavirus infection (COVID-19) and influenza vaccine. In this regard, a British research team has published findings such as side reactions and effects when two vaccines are given at the same time.

A study of co-vaccination with influenza and COVID-19 was led by a research team at the University of Bristol, and the results were published in the medical journal The Lancet. At the time of writing the article, the treatise has not been peer-reviewed.

The research team conducted a survey of 679 subjects in 12 locations in the United Kingdom between April and June 2021. According to the New York Times, all subjects had been vaccinated with the first COVID-19 vaccine, and the vaccine type was Pfizer / Biotech or AstraZeneca. Subjects received a second COVID-19 vaccination during the study period. At this time, the research team randomly divided the subjects into two groups, one group receiving the influenza vaccine at the same time as the COVID-19 vaccine, and the other receiving the placebo injection instead of the influenza vaccine. The two injections were given to another arm on the same day.

A total of three flu vaccines were given, but observations showed that side reactions such as fever and pain were 'mild to moderate,' the researchers said. In addition, even when comparing the case where the two vaccines were inoculated at the same time and the case where the two vaccines were inoculated separately, there was no difference in the effect.

The Centers for Disease Control and Prevention (CDC) has previously recommended that the COVID-19 vaccine and influenza vaccine be given at intervals of 14 days, but at the time of writing the article, the content was revised and 'can be given at the same time.' It explains .

2020 was also effective against the infection control influenza for COVID-19, the onset number of influenza that was less than in previous years has been reported . However, in 2021, the progress of vaccination with COVID-19 has eased infection control measures, and there is concern that influenza will explode.

The Japanese Society of Infectious Diseases also said, 'Because the number of people who got influenza in the previous season was small, there is a possibility that the herd immunity of the whole society has not been formed, and if the virus is brought in from overseas in that state, it will cause a big epidemic. There is a possibility, 'he said, and it is recommended that he be actively vaccinated against influenza. If COVID-19 and influenza spread at the same time and an unprecedented 'twindemic' occurs, it is expected that the medical system will be overloaded.
