2 jabs of AZ vaccine give zero immunity after 15 weeks to omicron variant, page-135

The vaccine was good for the Alpha variant.

We have since had Delta and now Omicron.

But within a few months boosters will be designed for Delta and Omicron.

Getting a new vaccine roll out in 3 months is impressive.

First antivaxxers complained that not enough trials were done for years and now new boosters are too slow to arrive.
