Doing vaccine against Covid and flu together? It could increase the side effects

EMA’s decision to extend the fourth dose of the anti-Covid vaccine to the over 60s and frail subjects is recent. The vaccination campaign began on July 13 and will continue after the summer. And from September, as every year, we will also start talking about the flu vaccine: the age target is more or less the same. According to a new study conducted in the United States, however, we should try not to overlap the two injections.
