The answer to all these questions is no. The vaccines worked for months, they work now and everything indicates that they will continue to work at least in the near future.
Vaccinated people are going to be more protected than unvaccinated people and there is no sign of RDW.
In fact, what all this means is that we are vaccinating a lot and that you always have to read beyond the headline.
Why do they say that there are more hospitalized vaccinated than not vaccinated?
The first thing we have to keep in mind is that most of the people hospitalized for covid-19 are people who belong to risk groups, mainly people over 60 years old. In fact, this is the main reason why these groups are precisely the first to receive the different vaccines.
