You forgot to read the most important part!

Effectiveness against hospitalisation of over 90% is also observed
with the Delta variant with all 3 vaccines (3). In most groups there is relatively limited waning of
protection against hospitalisation over a period of at least 5 months after the second dose.

High levels of protection (over 90%) are also seen against mortality with all 3 vaccines and
against both the Alpha and Delta variants (7, 11, 3). Relatively limited waning of protection
against mortality is seen over a period of at least 5 months.

Cheer up! The vaccine works! Go get it!
