You're not comparing apples with apples though, 38 people were ill enough to be admitted into hospital during a lockdown where people were told to only leave their homes for the most essential reasons. This summer there is likely to be much more social mixing, and much more virus circulating mean all of these vaccinated and all of the unvaccinated people will be far more likely to come into contact with the virus so sadly that figure will shoot up.
...and you're missing the point as yet again you seek to find any hint of doom and gloom in all things Covid-related. The data is in relation to vaccinated people, and the EXTREMELY SUCCESSFUL results shown from just a single vaccination on preventing serious illness and death. We already know the young and otherwise not vulnerable are highly unlikely to get seriously ill, and the data (which will be fully exposed later this week - possibly today) is going to show that virtually everyone who has been vaccinated (with even a single jab) is unlikely to go into hospital, let alone die.
