Multiple Choice

¿Cuál de las siguientes afirmaciones sería la más acertada sobre qué estrategia es más efectiva para generar una protección duradera contra el Virus X y por qué?

• La vacunación es la estrategia más efectiva para una protección duradera porque estimula al sistema inmune del individuo a producir sus propios anticuerpos y células de memoria, lo que permite una respuesta rápida y robusta ante futuras exposiciones al Virus X.

• Ambas estrategias son igualmente efectivas para la protección a largo plazo, ya que en ambos casos el cuerpo tiene anticuerpos circulantes que reconocen al Virus X.

• La inyección directa de anticuerpos de caballo es superior porque proporciona una inmunidad inmediata y más potente, ya que los anticuerpos ya están formados y listos para actuar.

• La vacunación es mejor porque los anticuerpos generados por el propio cuerpo son intrínsecamente más fuertes y pueden reconocer otros virus similares.
