Which vaccine is used to prevent varicella infection?

Explanation:
The key idea is matching a vaccine to the disease it prevents. The Varicella vaccine is specifically designed to protect against varicella-zoster virus, which causes chickenpox. It primes the immune system to make antibodies so you’re less likely to get varicella or have a milder illness if you’re exposed. The other vaccines protect against different diseases—DTaP targets diphtheria, tetanus, and pertussis; the meningococcal vaccine targets meningococcal disease; the HPV vaccine targets human papillomavirus. So the Varicella vaccine is the one that prevents varicella infection.
