“COVID-19 deaths in California among vaccinated rose sharply with omicron”
Yes it is true. This is why they were pushing the boosts so heavily; what was fully vaccinated against Delta was less effective in Omicron because of the mutations requiring the booster.
Had people listened during Delta and not continued advocating AGAINST public health recommendations and actively fighting against it, it’s likely that Omicron might not have occurred in the manner it did.
The difference between Boosted and vaccinated and unvaccinated is very clear: 436 deaths of boosted vs 2999 deaths of unvaccinated is a huge difference.
