Why should we still get the quadrivalent vaccine if there are free vaccines available?

There are several reasons for choosing the quadrivalent vaccine even when free vaccines are available, including reduced side effects, more comprehensive protection, and time savings. The specific analysis is as follows:

1. Reduced side effects

Receiving multiple separate vaccines increases the likelihood of injection site reactions or other adverse effects. In contrast, using the quadrivalent vaccine directly can reduce such side effects.

2. More comprehensive protection

The quadrivalent vaccine not only protects against diphtheria, tetanus, pertussis, and pediatric encephalitis, but also helps prevent influenza.

3. Time savings

Receiving free vaccines typically requires multiple visits to hospitals or clinics, consuming considerable time. The quadrivalent vaccine is more convenient and saves significant time.

In addition, receiving the quadrivalent vaccine also helps reduce infection rates, prevent complications, and enhance immune function. It is recommended to complete the full vaccination course correctly under the guidance of a healthcare professional.
