Schedule both 1st and 2nd vaccine at the same time. I am not able to get the second vaccine scheduled for the elderly members of my family. They never received the email. They will be showing up during the week of the due date. Be prepared to see a flock of old people on the evening news. Feel free to contact me, Terry 602-568-4400. I know of at least 20 young people who received "walk up" vaccines..... These elderly people are not to be messed with.....
