The quadrivalent vaccine requires a total of 3 injections, and the preventive effect will only be played clinically after the 3 injections are completely administered. 2. Pain will occur at the injection site, which will generally improve on its own in about 2 days. 3. It is recommended to drink more water during this period. 4.
