Covid Vaccines: The Good, The Bad, The Ugly

 

From Swiss Policy Research:

It is starting to look like any benefits from the mRNA shots disappear after 6 months. But does the Bell’s Palsy?

The latest data from Israel, which has used primarily the Pfizer mRNA vaccine, indicates that vaccine effectiveness against Delta coronavirus infection and symptomatic (“mild”) disease has dropped from about 95% to about 40%, whereas effectiveness against hospitalization and severe disease (i.e. low blood oxygen levels) remains at 80% to 90% (see chart above).

Importantly, in people who got vaccinated already in January 2021 (primarily the elderly), protection against infection and mild disease may already have dropped to near 0% (see chart above). Moreover, since the Delta covid outbreak is still accelerating in Israel, the effectiveness against hospitalization and severe disease may further decrease (due to lags in hospitalizations).
