There are a few facts to bring into this conversation. The first is that our vaccine allocation was reduced by 38 percent, and as a result of that, we don't have as much vaccine as we did for the first shots. The second is that the immunity conferred by the first shot is 92 percent, so people who have had their first shot have almost as much immunity as the person who has had two shots. The final point that I would like to make is that there is a period of time where people can receive their second shot without any hardship to their first one, that is no loss of effectiveness, and that is up to 42 days. We have already spoken publicly about the fact that, because of the reduced vaccine shipments, some people will end up waiting longer for the second shot, but rest assured; there will be a second shot within that time.
