@tiggerbluedevil @mskathleenquinn @andyaschmidt Measles vaccines are very effective against transmission, covid vaccines are not. Measles is also more responsive to contact tracing and ring vaccination due to longer incubation period. The response to each pathogen is going to be different.
@tiggerbluedevil@mskathleenquinn@和Yaschmidt麻疹疫苗对传播非常有效，而新冠疫苗则不是。由于潜伏期较长，麻疹对接触追踪和环形疫苗接种也更敏感。对每种病原体的反应将是不同的。
