@JeffCavanagh1 @Vanny_41 @SharkawyMD @lisa_iannattone Not 70% for long. If you want to avoid infection, you need to keep the virus out of your airway. Masks, ventilation, outdoors. Vaccine will keep you from getting as sick if it does get past the other precautions.

@JeffCavanagh1@Vanny_41@SharkawyMD@lisa_Iannatone长期以来没有达到70%。如果你想避免感染，你需要让病毒远离呼吸道。口罩，通风，户外。如果疫苗确实通过了其他预防措施，它将使你不至于生病。
