Coronavirus: Breakthrough Cases Part 3

Are United States breakthrough cases going to grow in numbers? If this Politico (Sep 14) article correct, the answer might be yes:

The Biden administration’s push to roll out coronavirus vaccine booster shots this month has largely been shaped by unpublished data from Israel’s vaccination campaign, according to two individuals familiar with the matter.

The Israel data, which is set to be made public as soon as this week, shows that the Pfizer vaccine’s ability to prevent severe disease and hospitalization is waning over time — as is the shot’s protection against mild and moderate disease, the two sources said. 

. . . Although the CDC has published a series of targeted studies that suggest Covid-19 vaccines’ effectiveness against infection is decreasing, particularly in the elderly, the Israeli data is more comprehensive and more alarming, three sources who have reviewed the data told POLITICO on Monday.

If the Israel data is accurate -- and why wouldn't it be -- we're going to start seeing cases among the vaccinated rise. 

Could that explain why (LA Times - Sep 15) "Los Angeles county plans to require proof of vaccination at indoor bars, nightclubs, breweries, wineries." Of interesting note, this plan was announced the day after the California governor recall election.
